what internal voltage tdoes the meter apply to test resistance?

I just checked mine on a Simpson 260 and a Fluke. It is about 1000 Volts open circuit

Sorry Calvin, I think this a great meter, however, I only use it to check the voltage on my AA and AAA batteries and rechargeable batteries from Amazon..... Works Great ! Phil Pauls Valley, Oklahoma

i dont know.just hook an ammeter in series with it and a battery and you'll find out

I used this meter for general use low voltage 1v -28v dc and some 110v ac. This meter is auto ranging. Looks like your looking for meter that measures milli volts below 1 volt I would not buy this model.

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).

Sorry, this one won't be suitable for such accuracy. For making effective low-ohms measurements you're going to really want something that does 4-wire Ohms measurements as the IR losses in the measurement wires will be significant if the total resistance under test is so low. Unfortunately those do tend to run several hundred dollars at a minimum.

You get about 9.5 V not under load. (i.e. when the unit is measured into a high impedance voltmeter).

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

Yes, any ohm meter will. You check the diode in both directions. Resistance will be found in open direction and open in the other. Two opens or two resistances= bad diode.

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

A multimeter shows the V+s are internally shorted as are the COM terminals, though I haven't tried running a 20A load through a single terminal or splitting it.

YesVoltage side, red wire to +5Vdc supply and black to 5V negative side.meter will read 5.0VdcThen On the current side, red wire to +2Vdc, and load + side.and load negative side to yellow wire.Black wire to 2V negative side. now the meter will read 2V load current.

Meter Power supply, two pin / wires = red & black are 4.5 to 30 volt input for meter display. (separate from measuring / test voltage). Can use a 9 volt battery. Second connector: 3 pin / wires for measuring under test voltage & current. "IN, "PW" & "COM". Connect "PW" to positive side of circuit under test (+) and "COM" to (-) of test circuit; for the voltage readout on meter. Connect "IN" to load side of shunt. V-cal & A-cal are the adjustments on the P.C board for calibration purposes. The data sheet does not specify this very well. Needs more verbiage in directions department.

There is a tolerance in its output. I do not remember what it is but the instructions that came with the unit and its maker can give you the specifics.

Ebay sells it. But make sure it's the 1 ppm, if that's what is recommended for the meter. That's the one I use.

The way to check it with a meter, is for continuity, not voltage. Put your meter on OHMS and check between the battery neg post and where the cable attached. You will see it reads "Open" when the knob is turned clockwise to loosen it. When tightened the connection is completed and you will have continuity "0". Proven that no electricity will flow with the knob loosened.
