Yes. the watt button gives you instantaneous power usage.The KWH kilowatt hour button gives you power consumption over time.For example, keep your refrigerator on it for 24 hours tells you how muchpower it uses on a typical day. The meter doesn't have batteries. It uses a small amount of current to operate. a power loss would lose the measurement.

Once the device is removed from the power source, the data is lost. Our customers plug an appliance in for 24-48 hours, get the total kWh during that time and determine what percentage of their monthly utility bill is going to that appliance.

Yes it does but you must understand KWH. The cumulative usage is dead when you un-plugthe POWER SOURCE, the USE SOURCE can bechanged but that does not effect the cumulativeusage through the device ie, if no power-failuresoccur then it could run until 9999 KWHs is reachedand that would turn over to 0000 KWH, and thecycle goes on. At MAX current that would be17,998 hours before roll-over, or about2.05 years in normal time.

It really will not give you flow ***RATE*** (e.g. gallons used per hour), unless you TIME your usage. It simply provide the gallons (or liters, depending on your selection) that flow THROUGH it, including cumulative. It not necessarily provide usage DETECTION unless you continuously check the cumulative amounts to see if they are different. It's truly (and simply!) a water METER. Hope this helps! I'm REALLY liking mine for my RV. I know how much water I put in my tank, or use when connected to "City Water".

Yes, it does measure long term. After 30 mins of being plugged in it switches to an "averaging mode" where it will track average cost based on your personal usage either on a monthly or yearly interval (by means of both cost and energy use). Also, you can fully cusomize the cost per kWh to provide an accurate cost estimation based on your home energy rates.

It shows that the power is successfully connected. It goes out but never lets you know when fully charged. Sorry, I just let it go for a few hours.

It only measures current (not voltage, not power factor) and calculates kW and kW-Hr from that so it's not the most accurate tool for the job. The reports and stuff are good enough to do that, if you can live with perhaps 10% accuracy.

If you mean you want to know how far you walked that time, it certainly displays that information on the screen. But if you mean cumulatively over time, it doesn't display that. Like other users mentioned in the comments, I've had trouble syncing the thumb drive to my online membership. For some reason, it never transfers the data. But I go online after each use and plug my information in (which really only takes about a minute or two) and the online system has kept track of my information for over 2 years now. So I can see monthly, yearly, and overall data on usage. If there's a way to track cumulative distance on the treadmill itself, I don't know about it.

It has a battery gauge on the display and you can perform a self-test on it. I assume it would tell you after the self-test that it doesn't have the expected capacity.

No it does not store any data for future review. It displays only real time voltage information which is lost when disconnected to power source.

It accumulates data only while it is plugged into a powered outlet. There does not appear to be any way to segment time; it starts counting the seconds of activity immediately after going through it's initialization sequence and does not stop until you kill the power. Anything plugged in and running will show data. It displays watts being used, amps being used, total kilowatt hours, kilowatt cost, line voltage & frequency and hi & low wattage use. It seems my shredder pulls 1.2 watts and 0.089 amps while sitting idle so I turn it off while not shredding something.

I haven't noticed an increase on my electric bill and haven't measured electricity usage specifically for this device. It does go into a sleep mode when not in use. When we are going to be gone or won't be using the computers for a while ii usually turn off the power supply for this and the rest of my network peripherals.

Its supposed to turn off, and reset to zero after a period on non use. The top reading will reset to zero, the bottom reading will not, and is cumulative.

It does not maintain a record, it is simply a snapshot of what the current voltage is. Also, it does not have an alarm, again, it's strictly a visual as to what your current voltage is.

Yes it accumulates and tells you for how long it's saved the data. It tells you the cost as well as long as you setup the the kw/h price in the settings.

It is just a power consumption meter with multiple displays.You have to do the math.

It does but it's not always accurate. Only because it's not real time. For example if you wake your computer it will show the % but that % is what it was at the last time you used it so after a minute or two adjusts to the actual %. Hope that makes sense :)

No, it only acts as a switch to control one of the two outlets, based on the commands of the controller. Amount of Watts used is not tracked by this device.

it can give instantaneous readouts so just have somone watch it while applying your peak load, you can also see what voltage your outlet is deliveringa and at what frequency, not all outlets are equal and power company delivery can be uneven.
