What is the smallest current that can be measured with the clip on ammeter?

DC, Range 400A, Accuracy + or - (1.5%+5), Resolution 0.1A ; Range 1000A, Accuracy + or - (2.0%+10), Resolution 1A ; AC, Range 400A, Accuracy + or - (2.0%+5), Resolution 0.1A ; Range 1000A, Accuracy + or - (2.5%+10), Resolution 1A

Not sure how small but the display comes up as 000.0 and I have read .5 amps. Hope this helps.

I doubt it very much. The meter requires power from the USB charge port. If you removed the power from the charge port to see if there is a discharge, the meter would not be powered. Your best option would be to modify a USB cable and connect in a milli-ammeter

I just ordered my device, so this "answer" is from principles only. To measure DC current one puts a low ohm resistor IN LINE (in series) with the current carrying wire. Then one measures the voltage drop across that resistor and computes the current by Ohm's law (actually the device does this for you). The resistor can get hot, so it must be air cooled (hence external). It appears that the shunt is included (see picture).

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.

Clamp resolution is .01 A or .1 A. The meter also can function as regular multimeter using lead wires. In such case the resolution can be selected as 1 microA or .1 microA. A word of caution - do not confuse resolution with accuracy.

Not sure of current draw but it's very minimal. Only uses an 1 amp fuse. Works great!

That depends on a lot of variables. But, the best clamp meter for me is this one (search on this number): B003LDFVBG

It will read 10 amps with out a external shunt. If the external shunt develops a voltage drop of 75 millivolts @ 100 amps. The resistance of the shunt = .0007 ohms. The ammeter internal shunt @ 10 amps would have a voltage drop of 7.5 millivolts. The power dissipation would only need to be 75 milliwatts. Easily done with surface mount components.

I'm not sure. The probes look like standard diameter tips. If the clip you're talking about will push into a standard probe then I would think so.

I do not have a micrometer to measure the probe, but, the answers given by OBX Joe and Larry Bevans are both good, useful information.

Not with the included probes, you'd need an amp clamp to do that. Their clamp style probe has low resolution with currents under 1 amp but I've heard their thread-style amp probe is more accurate with those situations.

I do not know of any meter that does that. To read DC Amps, you have to remove a lead wire from it's termination point and attach one of the leads from the meter to the wire end. Then you attach the other meter wire to the now vacant termination point. In short, the meter acts as a part of your power wire.

No, the probes are used to measure voltage. You must use the "clamp" feature to surround the wire you want to measure the current flowing through.

yes. look up "igaging spc usb cable for micrometers" (on amazon), there's a picture of that cable with this accuremote micrometer plugged into the top (the flap hides the mini(?) usb port).

If it's only one strip, it will draw about 2amps so this meter will not read that accurately. Get one that has a built in shunt that will measure 5 or 10 amps and won't require the complexity of adding a shunt.

Yes. You can search amazon for a current transformer, sometimes called a current tap. There are closed types that slip over the wire (usually cheaper) and open types that can be snapped around the wire like a regular clamp on ammeter. I don't know the ratio that you need for this meter. I suspect that it is a 100:0.1 ratio. This means that when the wire you are measuring is running 100 amps ac, the output from the current is 0.1 amp ac. If you are planning on switching between current sensors so that you can use one meter to measure multiple wires, you do need to be careful. The open circuit voltage on the current transformer can be dangerously high. I've been tempted to do this but have decided against it.

I use it to detect bad magnatrons and transisters, and it will show a difference of 1 ohm, the only one I have that will go that low.
