Does the AM-570 industrial model measure DC milivolts? Thanks.

Measures AC/DC Voltage up to 1000V, AC/DC current, resistance, frequency, capacitance, temperature, and duty cycle

Yes, you can measure both AC & DC voltages up to 600 volts. When measuring resistance (ohms), the circuit/device is normally not powered. As far as I know, this meter doesn't measure AC impedance (like DC resistance).

The converter itself has a max output. The ammeter actually measures the output current going to the load

There's no way to measure DC current with a clamp. All DC Amp meters use Hall Sensor to measure the magnetic field of the wire, thus estimate the current. In order to make this work, you have to Zero the reading every time before use, and make true it will not pick up interference magnetic fields. For the question you asked, most likely it's because there is magnetic field around and it's converted into current readings.

It will read DC Amps but accurately, I was reading a 3Amp load. I would suggest with all cheap meters to replace the probes and spend a little money $15/20 on a decent set of probes. Then it will read DC amps accurately once I replaced the probes.

This monitor doesn't have a voltage sensor (AC current is measured by inductive clamps and the voltage is entered manually on the display), so it can't compute power factor or adjust for phase mismatch. I haven't tried to check its accuracy, but other reviews I've seen have said that people find it to be reasonably accurate.

It is an AC detection unit. It does not measure DC so polarity of the coil is not important.

It will measure current well under 5A DC. I've been told clamp on meters aren't very accurate and I think this is compounded at lower currents when the coil is influenced by other stray fields. When I went outside and did a little testing with my trickle charger (and leadtype multimeter in series) I found that it's quite accurate (within 10%) down to 0.5A but when I got to the 0.05A it was out by up to 75%. I think your results will vary depending on environment.

It measures to .01amps. I use it for that very reason and suceesfully found a short on a 12v gmc van.

There's a nice load vs. time graph on the product information page on APC's website. At this writing, the page can be found at <http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SMT1500&total;_watts=1000>

Yes, it should say DC not AC. Added note: I am extremely pleased with the way works.

You don't. On AC, the meter ignores any DC component, so any DC offset is ignored.

Have a look at the back of your power brick (you may need magnifier, I do), it will have an output value saying ___ VDC. If that is 12 or 19 then you should be good to go.

I haven't try it w/12VDC but... it does have the connector for DC on the side.

It will measure to .001a/AC-DC but will not calculate amp hours. Milli amps yes.

Will this meter measure the DC current being drawn (like, from a battery)? YES!Just remember, it is a digital meter, so it is better suited to measure steady current. If the current fluctuates, the digital readout may look to be jumping all over the place.
