Can this measure microamps? I'd like to get my project's power usage down to the microamp level, and I want to be able to measure it.

You might be disappointed. Meter can measure down to 10 micro amps according to the manual.

I am not sure what you are trying to determine. I don't have the test equipment to measure the small amount of power that this consumes. I did plug it into my Kill-A-Watt power monitor. The power consumed after 90 minutes still registered as zero. The instantaneous current and power were also zero. The device reads out to 2 decimal places so the power and current must me less than .00 amps and .00 watts. It is a very low power consuming device, exactly how low I am not sure. It is obviously not zero, just very low.

There should be a UL label on the bottom of the machine which states its watts and/or amps. UL is a third party evaluation group that gives accurate information. Could someone who has one of these machines tell us what it says?

The clamp is not that accurate. I think its good for testing starters, alternators, etc. I just don't think it would it would work for trying to see less then an amps worth of difference. I wouldn't bother using it to measure anything less then 10 amps.

I would check the watts and amperage first. I didn't but you might be on to something.

It only shows runtime, load capacity and voltage. For watts you should look into a kill-a-watt device like this one: http://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU I have one of those and it works great. Plug it in before the unit, then plug the unit into it and you will have the watt display of the whole ups.

It Doesn't work, I wanted to do the same thing. I purchased 3 of these from different sellers, but none would work measuring amps.

I believe it can measure 120, 240 or three phase power. It comes with TWO current probes.If you only attach ONE and restart I believe it will measure 120 volt single phase. However, if that is all you want to do , buy a Watt Wizard for much less money.

Are you asking how much current this meter requires to work? If so I wouldnt imagine very much at all though I dont have a definite number. Putting a resistor in series with the meter would affect the voltage reading. What exactly are you trying to do?

It doesn't measure wattage. I use a combination of rpms and resistance to measure progress. Not convenient if you're used to wattage. Resistance is computer controlled and is magnetic which means it's quiet and efficient. I like it a lot so far.

Does this unit measure watt usage. I'm on solar and want to see ceiling fan usage independently as will as everything on at one time. Not concerned about total KWH and cost. Too, do I see where the unit clips on inline feed and then there is a remote that I can carry around without a computer. If so, this is what I'm looking for.

Try running something not as power demanding and see if it works. Do you have a multimeter? What type/capacity battery is it? How are you charging the battery?

I don't know what you want this gauge to do. IT measure amps volts, wattage. load, and Cycle. It doesn't know how many AH Capacity your batter is. Hope this helps RC

dont know... for future reference; get a resistor and measure voltage drop then calculate the current, ull blow a MM everytime trying to "direct measure" amps

It will monitor total wattage. But you will know how much each individual device consume once you turn it on.

i think it is more up to local code, but i plug it. It only draws 8amps, so i don't see why it would not work.

I was unable to get the meter to read low amps. It would show amps when the load reached 40 amps and higher. Tried everything even with shunt. Customer was content to having a volt meter that would show voltage dropping on the inverter system.
