How It Works

 

Q: Can Watts up? measure a clothes dryer, hard wired lights or a central heating/cooling system?

A: Watts up? only measures devices that can be plugged in. However, in Q4 2008 (possibly beginning of Q1 2009) we will introduce a hard wired version for permanent applications, and for larger loads.

Q: Can Watts up? be used with solar systems?

A: Yes, Watts up? accurately measures the power, even with inverters (many power meters cannot). For systems that are connected to the grid, the meter will show just how much the utility owes the consumer! One customer using solar energy discovered how his usage capacity declined as clouds rolled in.
*Some inverters have extremely fast rise times and can damage the electronics. The .Net is recommended if using with an inverter.

Q: Can Watts up? be used as an educational tool?

A: Many schools use Watts up? to educate students about electricity. Lessons are designed for 5th grade all the way through high school. In fact, numerous advanced placement courses, as well as colleges, use Watts up? for educational purposes. Many educators find Watts up? is a great way to link classroom concepts to real world solutions.

Q: How does Watts Up? work?

A: Both the Watts Up? and the Watts Up? Pro display 18 measurements and values, including the wattage being used by an appliance, as well as the cost in dollars and cents. The difference between the models is that the PRO is a data logger, which means it records the data and can download it to a PC. The included software provides a data table and easily manipulated graphs of all the data. Also included is the Payback Calculator, which determines just how long it will take for a new, more energy efficient appliance, to pay for itself. This information can prove invaluable when considering the purchase of a new major appliance.

Q: Does Watts Up? save electricity?

A: The new .Net model introduced in October 2007 actively saves electricity. With an internal switching relay, the .Net can turn off power to the end load based on user configurable rules. These rules and their associated application include:

Time of day- Effective when your utility has TOU (time of use) rates, where they charge a higher rate during peak times

Peak usage (watts)- For commercial accounts, which are typically charged a surcharge if their consumption ever surpasses a peak threshold during the billing month. Having multiple .Net meters can enable you to simply and economically "shed power" and keep you under the threshold.

Cumulative usage (wh)- Use for tiered pricing rates, when higher usage is billed at a higher rate.

Manual on/off - For security reasons, rebooting servers, or while on vacation.


In addition, all Watts up? models certainly help you determine where electricity is being wasted in your home and/or business. For example, one Watts Up? user discovered that his freezer compressor was running 19 hours a day! A repairman was brought in to recharge the Freon and the freezer's power drain was cut in half!

Meter operations - USB versions

 

Q: When I plug in the meter it needs to “warm up” for an extended period of time before a computer will recognize it.

A: The reason the meter goes through the warm up period is that the meter once re-powered; will do a line by line search to find the last data point in memory – so that it can automatically resume recording data upon re-powering. This was written this way to ensure that if power was disrupted in the field due to power outage, brown-out, or someone accidentally un-plugging the unit – that the meter would resume logging with our needing someone to initiate it. The downside is that it must go through this search loop prior downloading.

So, if you collect 100 LINES of data with 3 parameters or all 18 parameter – the warm up period and download time will be the same. However – if you collect 200 LINES or Samples of data – this would take twice as long (than a 100 LINES). This being said – in some extreme circumstances we have seen up to 15 minutes of warm up.

Q: My meter shows EE on the screen, what does this error mean?

A: A: This indicates a software error. It might be that the firmware is old. You can check the firmware by unplugging the meter then plugging it back in. The version of your software will flash on the screen. Please contact customer service at orders@wattsupmeters.com or call 1-877-928-8701. The error can also be caused by bad calibration. Try unplugging the meter andplugging it back, which will reinitialize the meter. It the problem contiues, contact us at customer service for further information.

Q: My watt hours seem to start over at 0 after logging 24,000 – 25,000 watt hours.

A: The meters record the cumulative watt hours. The resolution is maintained and the number is not truncated to show only kilo watt hours. This means the number eventually gets very large. Depending on the model, the largest number allowed is either 25,000 watt hours or 250,000 watt hours. For most plug loads, this will never be reached. If your meter does reach the maximum number, the counter will reset to zero and continue incrementing. To get the actual total, simply add the largest number recorded to the remaining values.

Q: Is the USB software compatible with 64 bit operating systems?

A: Yes, it is, however, you will need to install the drivers that are compatible with the 64 bit system. This also applies to XP and Vista systems if you have an issue. Please go to the following link for instructions on installing the correct driver version http://www.ftdichip.com/Drivers/VCP.htm. Currently the driver should be 2.08.24. Download the driver and save it to a folder. Then plug in your meter and go to Device Manager. Select the USB port that has your meter. It will say it is not working. Select update driver. Browse to the location that you saved the driver above. Unplug the meter and plug it back in. Select the USB port in Device Manager a second time (yes, windows requires you update the driver 2 times). Update the driver again. The meter should now work correctly.

Q: I get an error saying I need a 64 bit driver.

A: With Windows 7, some users experience an error message upon installation that says they need a 64 bit driver. This is typically installed automatically even though the error is displayed. So as long as the USB data logger software downloads data, everything is working normally, and the error message can be ignored.

Q: I purchased a meter from another store or website, and not directly from you, however it is not working correctly. What should I do?

A: If you are having problems with a meter you have purchased from another store or website, and not directly from us, please contact us at orders@wattsupmeters.com or 1-877-928-8701, for technical assistance or repair within the 12 month warranty period from time of purchase.

Q: Why does my calibration data seem corrupt on certain loads?

A: Some loads and environments cause excessive noise, which can corrupt calibration data thus leading to erroneous data. This is typically not a problem. But especially for industrial studies where the data is critical, we highly recommend the .Net. This model has significant hardware and software improvements to reduce the likelihood of errors. In addition, physically separate the load from the meter by using a 5-10 foot (1-3 meter) extension cord. This often resolves the issue. If you already have a PRO or ES, and don’t want to upgrade to a .Net model, then using a line filter may help.

Regarding the line filters, we suggest:

Q: I tried to clear the memory by holding the select button down but the memory is not clear.

A: A very small number of meters (less than 1%) display a very large number for kilowatt hours, and cost when the meter is first plugged in. Erasing or clearing the memory has no affect. However, once an appliance is plugged into the meter the value will reset to zero and the meter will operate normally. In October 2008 firmware version 4.57 solved this issue. If your meter has the older firmware version and you experience this problem, you can contact customer service at orders@wattsupmeters.com or by calling at 1-877-928-8701 to request the new firmware version be installed on your meter.

Q: What do I do if my Mode or Select button sticks?

A: Look on the back of your meter. You will see 4 rubber feet. Remove the two bottom rubber feet (the two feet under the mode button on the front of your meter) and loosen the screws about a half of a turn. Replace the rubber feet. You may have to press the mode or select button a couple times to cause it to release.

Q: I tried to download the USB software but my computer says it can't find the WinZip file, what do I do?

A: If your computer is running Windows XP or newer it is already in the system, but if not google Winzip and download the program onto your computer.

back to top

 

Q: My computer says meter not found, what do I do?

A: The driver probably did not install correctly. Download the latest Data logging software from our SUPPORT page. As of July 2008, our installation wizard should install it automatically but sometimes it does not. To correct it, navigate to:

C:/program files/eed/wattsupUSB

Double click on "DPInst.exe" This is a Microsoft application and according to Microsoft, the primary purpose of "DPInst.exe" is to install device driver without the necessity of having the hardware plugged in.

Alternately, with the meter plugged in and connected to the PC, click

START > CONTROL PANEL > ADD HARDWARE

A big list will populate. Scroll down and look for something called "FTDI or FT232 ........."

Select it and then go through the screens, selecting the option to manually select the location for the driver. When you have the option to browse, go to:

C:/program files/eed/wattsupUSB

Do this entire process twice (there are two drivers) and then see if it works.

If you have problems with this procedure, or if you don't see something called FTDI,:try:

1. Open Device Manager (Start button > Control Panel > System > Hardware tab> Device manager button).
2. Expand PORTS
3. Look for USB Serial Port (Com XX). If you cannot find it, check both ends of the cable connections and ensure the meter is plugged into a working AC outlet.
Try a different USB port on your PC. If still nothing, contact us.
4. Highlight it, and right mouse click > select properties
5. Click Driver tab. Verify it says FTDI as manufacturer. Select update driver or install driver.
6. Hardware update wizard starts.
7. Asks to connect to Windows update ‚ say NO
8. Select ‚ "Install from a specific location"
9. Browse to C:/program files/eed/wattsupUSB

Q: PC error: USB device has malfunctioned and exceeded the power limits of its hub port.

A: Try using a different USB cable. Our cables are standard cables, similar to most camera download cables. They are type "mini-USB to USB".

back to top

 

Q: What is the accuracy, and what are "counts"?

A: The meter is accurate to 1.5% of the load, plus 3 counts. Counts refers to the least significant digit. So for instance, on a 100 watt load, the meter displays tenths of a watt. So the least significant digit in this case is a tenth. 3 counts = 0.3 watts in this case. Therefore, the meter should display 100 +/- 1.8 watts (1.5% = 1.5 watts, plus 3 counts = 0.3 watts, for a total of 1.8 watts), or between 98.2 - 101.8 for a 100 watt load.

back to top

 

Q: Why does only the amps accuracy degrade?

A: For loads less than 60 watts, the current and power factor displays will have lower accuracy. However, the wattage and other displays will still be within 1.5% . So for instance, the meter should display 1.0 +/- 0.3 watts (1.5% = 0.0 watts, plus 3 counts = 0.3 watts, for a total of 0.3 watts), or between 0.7 - 1.3 for a 1 watt load. However, the meter will likely display 0.010 amps, which would be off considerably if the actual load had a low power factor and the actual current was 0.040 amps.

The amps lose accuracy even though the wattage does not because we utilize a power metering chip that is specialized for watts. Watts are integrated over 1 second intervals which helps eliminate some error, whereas amps are discrete RMS values for single sine waves.

back to top

 

Q: Why does the USB connection say "com 17?"

A: The meter uses a USB converter chip internally. This allows it to have a USB connector and port. However, the PC actually "sees" the meter as a serial port and thus assigns it a sequential port number. This number will vary depending on the specific configuration of your PC.

back to top

 

Q: How do I know if the meter is logging?

A: The "LOG" icon in the lower right corner of the LCD flashes off momentarily every time the meter logs data into memory. So if the LOG icon flashes off every second, then the meter is storing data to memory every second. If the LOG icon stays on all the time but momentarily turns off once a minute, then the meter is recording data to memory once per minute.

back to top

 

Q: I only want to log watts and volts

A: In the PC application, select METER SETTINGS > LOGGING tab, then check the watts and volts boxes.

back to top

 

Q: Can I measure 240 volts?

A: Yes, all meters manufactured starting in Jan 2007 are worldwide compatible. They will operate on 100-250v, 50/60 Hz, 15 amps. The label and rating is 120 volts because it has a NEMA USA style power cord. Beginning in November 2007, each model is available with IEC 320 universal outlets (UO) instead of integrated USA style cords. Universal outlet versions are rated at 100v - 250v, 15 amp, 50/60 Hz, and are also CE marked. Cord sets are sold separately, with country/voltage specific ends. Be sure to order the UO model when completing your shopping cart.

back to top

 

Q: Can I operate my UO version meter at 277 volts?

A: This exceeds the meter specifications of 100-250v, 50/60 Hz, 15 amps so it is not covered under warranty, but since it is only 10% higher than spec, in most cases it will be fine.

back to top

 

Q: Logging indicator (why is it blinking?)

A: The "LOG" icon in the lower right corner of the LCD flashes off momentarily every time the meter logs data into memory. So if the LOG icon flashes off every second, then the meter is storing data to memory every second. If the LOG icon stays on all the time but momentarily turns off once a minute, then the meter is recording data to memory once per minute.

back to top

 

Q: Memory full indicator

A: If the memory option is set to either FULL or OVERWRITE, then the "MEM FULL" icon will illuminate on the LCD whenever the memory is full. To clear the icon, erase the memory. The memory can be erased by holding the SELECT button down when the meter is initially powered up, or the memory can also be erased from the PC.

back to top

 

Q: CLR MEM? Indicator

A: The CLR MEM? Icon flashes for 5 seconds when the meter is powered up. This reminds the user to erase the memory if they are starting a new log of data. The icon can be ignored and it will stop flashing after 5 seconds.

If your meter is new and does not flash CLR MEM? when first plugged, you need to connect the meter to your PC. Install the Download software, install the driver, and then connect the meter. The initial communication between PC and meter configures the meter so that it "knows" it is a PRO.

back to top

 

Q: How is the min / max calculated?

A: Watts are displayed as an average reading over one second, so the minimum and maximum watts is highest and lowest watts the meter has measured for one second since the meter was last reset (unplugging the meter resets all of the min/max's. In addition, each individual min/max value can be individually reset .)

The amps and volts are displayed on a per cycle basis, in contrast to watts which is a one second average as explained above. So the min/max represents the highest and lowest measurement the meter has measured for a single sine wave cycle since the value was last reset.

back to top

 

Q: Can the PRO and ES do real-time logging?

A: Yes, the Watts up? Pro is capable of real time logging. You can order the optional Realtime Logging software on our order form.

back to top

 

Q: What is auto-sampling, and how is the sample rate figured?

A: Auto-sampling refers to the unique way the sample rate is handled for data logging in the Watts up? PRO. Some data loggers require the user to set or program in the desired sampling interval. This is often confusing and cumbersome. Instead, Watts up? PRO automatically provides the user with the highest resolution of data possible, regardless of how long they have been logging. In addition, nothing is required to be setup or programmed in advance.

Watts up? PRO always starts logging at a one second interval. When the data is filled, every other record is deleted, and the meter starts logging again at two second intervals. When the data fills up again, every other record is again deleted, and the meter starts logging again at four second intervals. This doubling of the sample rate continues indefinitely. So the meter could record for a years time, and the sample rate would be approximately every eight hours. The chart below shows an example.


Time logged Sample rate
0 - 17 minutes 1 second
17 - 34 minutes 2 seconds
34 - 68 minutes 4 seconds
Etc.

Q: Can the timestamp be automatically updated when I download?

A: Yes, the new revision of the software includes this feature. Go to the download section, and download a new version.

Wireless

 

Q: What wireless adapters can be used?

A: Connect a wireless adapter (for example the ASUS WL330GE Wireless pocket access point or the TrendNet TEW430APB (configured in client mode) into the Smart Circuit or .Net's ethernet port, and the unit can be used wirelessly. If using wifi with multiple meters, use a 'wireless bridge' - for example Dlink DAP-1522. Our customers have also recommended: The ECB 3220 – Engenius http://www.engeniustech.com/datacom/products/details.aspx?id=170 The UBIQUITI Nano - http://www.ubnt.com/products/nano.php

back to top

 

Q: How do I program the password for wireless?

A: The SSID and password (if used on the WFI network) is programmed into the WIFI adapter or wireless bridge. Nothing changes on the meter.

back to top

 

Q: Can I use the Smart Circuit or .Net with WIFI?

A: Yes. To WIFI enable one SC or meter, connect a wireless adapter (for example the ASUS WL330GE Wireless pocket access point or the TrendNet TEW430APB (configured in client mode) into the ethernet port, and the data will be transmitted wirelessly. If using wifi with multiple meters in the same location, use a 'wireless bridge' - for example Dlink DAP-1522 (connecting a switch directly to the DWL-G730AP will NOT work. The DWL-G730AP will only support one meter or SC). A switch can be used with a wireless bridge and then many units can transmit over the one wireless bridge.

Meter operations .Net

 

Q: When streaming data over the internet, what is the reliability of the data packets being received? Does any get dropped?

A: The .Net and SC20 Meters transmit data packet via Ethernet connected over http on Port 80. These raw data packet are then received by the our host / web server; or a client custom web application. The success rate for packet delivery ranges from 94% to 99% reliable. Loss or blocked packets are typically the result of firewalls and / or ISP (Internet Service Provider) reliability, or heavy internet traffic condition. Loss data packets do not effect the integrity of the data or study as the data and associated energy formulas are all computed within the meter's internal processing chip.

back to top

 

Q: How do you configure a .Net meter to a privately hosted web server?

A: First, you must write you own custom code; server-side application that can receive the data packet sent out by our .Net meter. Using the API, you can then parse and interrupted the data; as well as send commands to the meters. Secondly, you must change the basic setting in your meter. Using our free USB software, goto >Options>Network Setup (.Net Only). Here you will have 3 tabs; Basic Setting; Extended Settings; and Local Network. Under Extended Settings, you need to change the "Post Host" to the IP address where you want the data send to. This can be a host address or an actual IP address. Second, you will need to each the "File" to the desired post file. Lastly, if needed, the Post Port can also be assigned here; however most likely you will want to communicate over port 80. Finally, hit the "Send Extended Setting to the Meter" button to save you setting to the meter. You should un-connect and reconnect to the meter – to ensure your new setting have been written to the meter.

back to top

 

Q: Why are some columns not logging data for online meter information?

A: This means that your meter settings are configured to only log certain data. This can be fixed easily buy configuring the meter using the free USB software downloadable from our website.
Once connected to the meter select the "Meter Settings" drop-down button. Once the "Meter Settings" window has opened select the"Logged Items" tab. Push "Set All Checks" button. This will allow the meter to log all data. Lastly push the "Send Setting to Meter" button.
You should see all data points begin to update on you online meter data page.

Q: How do I view all 250,000 records in the downloaded zip file? I only see 55,000 in excel.

A: Excel limits the number of rows. To view all the records, you must use a database program such as Microsoft Access, Filemaker, mysql, or other database. In Access, take the following steps:
1. Download the zip file from the account on wattsupmeters.com
2. Extract the csv file from the zip file
3. Open MS access, and click new table
4. Select import table, and browse to the csv file. Delete the characters after the period in the file name, otherwise access will not find it
5. Go through the import wizard. When prompted, select the date/time column, and import it as text (not date/time)

Q: Will my .Net meter work with a dial up modem?

A: The meters work with any kind of internet connection; they are designed to stream data continuously and the meters work best with a broadband, or always on, connection since data will be lost when the modem is off. Generally, a dial-up modem is not always on; therefore, the meter will reestablish a connection each time the modem is activated, so it will work fine.

Q: Can I use my .Net meter with a wireless adapter?

A: Yes, Connect a wireless adapter (for example the Dlink DWL-G730AP or the TrendNet TEW430APB, both configured in client mode) into the meter's Ethernet port, and the meter can be used wirelessly.

Q: All of your products spec 2000m max altitude, per UL. What happens above 2000m?

A: The meters will work just fine at 3,000 meters. The UL certification only goes up to 2,000 meters, however the components of the meter work fine at higher altitudes.

Q: Why is the time stamp wrong on my data?

A: By default, the time stamp will be in Mountain Time zone. To change it so it is correct for where you live, select your time zone in your profile just below the address fields. Be aware, if your time zone is earlier than mountain (for example Pacific zone), then the next records will come in at an "earlier time" than the existing records. The records in the table are sorted by time, not record ID #, so you may not see new records until the local time is after the last records in your table.

Q: My meter does not display "kilo watt hours"

A: November 25, 2008 we discovered that the "kilo" symbol on the LCD was not turning on appropriately. The meter utilizes a "floating decimal" system, so that the highest resolution possible is always displayed. For example, in the watt hour display, the meter may display 6.70 watt hours after first being plugged in. After many days though, the display might show 3.72 kilo watt hours. The numbers are very close, but the "KILO" symbol indicates a difference of 1000 between the two values. The symbol is often used in the "Monthly Average watt hour" display, because when the watt hours are pro-rated to a month's period, the value is often in kilo watt hours. This bug caused the "KILO" symbol to never come on, making it difficult to discern the correct value. This was fixed in meters shipping in Dec 2008 with v5.01. If you have an older version and would like your meter upgraded, contact us at contact@wattsupmeters.com.

Q: Why does my meter have strange data?

A: Some loads plugged into the meter will cause data corruption and other problems, which can result in incorrect measurements. This is very rare. Elaborate filtering within the meter suppresses most noise before it causes a problem. However, the filtering works best when the meter is plugged into a grounded 3-prong receptacle, so please ensure you've plugged the meter into a proper outlet if you are experiencing problems. Power cycling the meter (unplugging it and plugging it back - yes, a reboot just like with a PC) will reinitialize the internal workings and should resolve the issue. It is also a good idea to verify if your meter needs a firmware upgrade. Please let us know if you are experiencing issues- send an email to contact@wattsupmeters.com .

Q: My LCD has strange segments or seems to "hang".

A: As of Nov 2008, we have received several (< 5%) reports of the LCD screen having all "1's", be very dim, or the meter being unresponsive as if it is "hung". This is caused by the TCP stack crashing. This can happen whether a cable is plugged into the ethernet jack or not. The stack we are using is from Microchip, who is the manufacturer of the microprocessor we use. If the stack crashes, it can cause lots of issues:
· Relay clicks once or repeatedly
· LCD dims or has all 1’s or something else weird
· Meter hangs
· Measurements are incorrect


New meter firmware v5.00 was released Nov 18 and includes an upgraded stack from Microchip. This firmware is more robust and more fault tolerant. If you are experiencing the problems listed above, EED will upgrade the firmware in your meter at no charge. Unfortunately the firmware can not be upgraded in the field, so it will require you to return the meter to the factory. Turn around time is just a day or two though. Sorry for the inconvenience. Send an email to contact@wattsupmeters.com if you are interested.

Q: Why does my meter make a "clicking" sound?

A: Inside the .Net model is a relay, which is used to turn power off to the end load. As of Nov 2008, we have received several (< 5%) reports of this, and also of the LCD screen having all "1's", be very dim, or the meter being unresponsive as if it is "hung". This is caused by the TCP stack crashing. This can happen whether a cable is plugged into the ethernet jack or not. The stack we are using is from Microchip, who is the manufacturer of the microprocessor we use. If the stack crashes, it can cause lots of issues:

Q: How do I verify if my meter is sending data on the internet (public or private network)

A: In debug mode, the meter will echo out the USB port all the communications. This output can be viewed using an emulator such as hyperterminal. The meter can be put in debug mode by sending it a #T,D,1,1; command (see API document on the SUPPORT page), or by pressing down the MODE button when it is first powered up. The post as constructed will be seen, and also the reply back from the webserver. If a timeout happens with no post, then contact was not made with the webserver. If a reply was received, it is possible to verify the current content and format.

Q: Can I access the meter from a web browser?

A: The meter sends and receives data over port 80 but it can’t output web pages. It is possible to assign the meter a static IP address, but it is not possible to enter that address into a web browser and communicate directly with the meter as many routers do for configuration purposes. The data packet the meter sends is raw data and needs to be parsed and formatted. Therefore, a web server application is needed to collect the information. We provide this functionality on our website and both free and paid accounts are available at https://www.wattsupmeters.com/secure/products.php?pn=2.

If you want to have the data remain on an internal private network, we recommend installing a server side application to collect the data. Use our API https://www.wattsupmeters.com/secure/support.php to develop an appropriate application for your needs, or to integrate our data into an existing application. We plan to offer an enterprise version of our web server application sometime in 2009.

Q: I have lots of meters. Can they all come up as the same com port number?

A: Yes, by default Windows will assign a new com port # for each meter. This will allow you to monitor several meters in real time separately over the USB but on the same PC. However, if you simply want to download data from lots of meters, or just configure them over the USB, it might be better if they all were assigned the same com port. To do this, you need to Set IgnoreHardwareSerialNumber in the registry. This is explained in chapter 7.1 (pg 20) in the following manual: http://www.ftdichip.com/Documents/AppNotes/AN_AdvancedDriverOptions_(FT_000073).pdf . Use Start > Run>regedit to access the registry editor.

Smart Circuits

 

Q: When using the Real Time Logging Software, why does the application freezes when I turn on the load

A: Some loads create extreme noise on the line. This noise may go through the meter, through the USB cable, and into the PC causing the USB port to crash and thus locking up the software. Physically moving the load away from the meter can dampen the noise so it is not a problem. To do this, plug the load first into a 10-20’ extension cord, and then plug the extension cord into the meter.

Q: How do I send the data to a different website?

A: By default, the SC will send data to www.wattsupmeters.com. The data is password protected so only you have access to the data. However, you can configure the SC to send the data to any IP address. The host, file, user agent, etc is configured using the PC application via the USB connection: options > network setup > extended settings

Q: How will Smart Circuit save me money?

A: -Reduce Costs Effective when your utility has TOU (time of use) rates, where they charge a higher rate during peak times. Smart Circuits can automatically "load shift" so loads are used during off peak times.
       -Reduce Peak Charges Commercial accounts are charged a "peak charge", which is based on the maximum amount of kilowatts used during the month, even if it was only for half an hour. Lowering your peak usage directly lowers your monthly bill. Smart Circuits can automatically "shed loads" to keep your peak usage under a threshold. For example, connect 25 Smart Circuits to your account, and configure our website to automatically turn off specific loads when the total power across all 25 Smart Circuits exceeds a threshold you designate.
       -Lower Consumption Many utilities now have tiered pricing rates, where higher usage is billed at a higher rate. This often happens toward the end of a billing cycle, which might be daily, weekly or monthly based. Smart Circuits keep track of total consumption and can automatically turn off non-critical loads once the high rate tier is activated.

Q: Do Smart Circuits have plugs like the Watts up? meters?

A: No, Smart Circuits are designed for permanent hard-wired applications. Smart Circuits are ideal for lighting circuits, outlet circuits with lots of vampire or leaker loads, large hard-wired appliances such as electric hot water heaters, washer/dryers, HVAC systems, pumps, blowers, and refrigerator/freezers. Smart Circuits are also ideal for home automation projects where it is important to remotely turn things on or off.

Q: I sometimes lose the connection between the PC and meter

A: Some loads and environments cause excessive noise, which can corrupt calibration data thus leading to erroneous data. This is typically not a problem. But especially for industrial studies where the data is critical, we highly recommend the .Net. This model has significant hardware and software improvements to reduce the likelihood of errors. In addition, physically separate the load from the meter by using a 5-10 foot (1-3 meter) extension cord. This often resolves the issue. If you already have a PRO or ES, and don’t want to upgrade to a .Net model, then using a line filter may help.

Q: Why do I get a "No Response" error when I try to download data?

A: A "No Response" error message indicates the software is not receiving any signal from your Watts Up? meter. Therefore, you should try the following:

1. Verify the meter is plugged in. It should display ~120v in the volts mode.

2. Make sure the cable is attached; it should snap into the connector on the meter. Verify the cable has been securely plugged into the computer.

3. Select a different Communications (COM) port.

back to top

 

Q: Why do I get an "Improper Response" error when I try to download data?

A: If you are given an "Improper Response" error message, you should first check to see that you do not have any additional applications, such as Palm Sync, using the same serial port to communicate with the devices. Even if these devices are not connected, they are often running in the background and cause communication errors.

Secondly, verify that all settings are correct on your Com port. Then, under the View tab, select Communications Log. Confirm that the data is being communicated back and forth.

Q: How do I get the sample rate to become one second again?

A: Unplug the Watts up? meter from the outlet, wait a couple of seconds, and then plug the meter back in. The meter will flash "RESET? LOG" for approximately ten seconds. Now, simply press and hold the Select button for one second. Once the "RESET? LOG" symbol stops flashing, release the Select button. The meter will now resume normal operations.

Q: I have the ES version, but it stopped logging?

A: The ES version stops logging when the memory is full. You can tell that the memory is full because the "RESET?" symbol will be flashing every few seconds. To restart logging, download the data if you want to save it, and then erase the memory from the PC application or by pressing the SELECT button down after first plugging the meter in.

Q: When I export to Excel, the time stamp is messed up?

A: Excel likes time represented in days, whereas the Watts up? software represents time in hours. To fix the time in Excel, insert a column next to the time column. Divide the Watts up? time by 24. Format the new cell as a "date" with day and time. The time in Excel should now match what you see in the Watts up? table.

This was changed in meters manufactured in 2007. After Jan 2007, the Wattsup? Software represents time in days so nothing needs to be converted.

Meter operations - original (prior to 2002 - these models have a SET button)

 

Q: What does the 2T mean?

A: This represents a second rate structure, based on volume pricing. Some utilities charge a higher rate after a certain level of electricity is consumed. It is similar to tax brackets, where one pays a higher rate the more money they make. In practice though, since the meter measures plug loads, it is difficult to demonstrate this application since there is never enough load on any one outlet to accumulate to a big enough amount. It was removed in subsequent models. Basically, it can be ignored.
