can I use this meter to measure a negative voltage?

Yes A negative sign (-) will display on the meter when checking DC voltage and the meter leads are incorrectly placed on the voltage source. When the meter leads are reversed, then the negative sign will not appear.

It will automatically measure that I believe. Never tried to measure the opposite direction

Yes..Put Your red lead on the ground. The Black or ground lead to the neg. voltage. To the meter, the ground will appear as a positive voltage in comparsion to the negative voltage.Read the meter just as you would when measuring a positive voltage.

U can zero it by touching the leads together...most meters do the same thing and depending where u r there is electricity all around as is shown on am oscilloscope.

yes , it is very easy to read all the voltages, any not with in specs the reading will be in red . I do have the old style tester and bought this one and have been using it ever since. I am keeping my old tester as a back up in case it fails.

I have no idea and I'm not going to try.In general the meter seems pretty robust at measuring large, variable loads in the direction it was designed to measure. My application was an electric bike with a typical voltage above 50vDC and loads all the way up to 1.5kw.

The aux pwr connection must be at least 4v. The min volt reading can read down to zero v with the same accuracy...it cannot read negative Volts.

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).

No...used to measure circuit installation..grounding, reversed polarity, open neutral, ect.

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.

Cannot answer your question exactly but suggest you look at the following link - https://www.youtube.com/watch?v=ZoeUgMFLyAw.It will give you a GOOD insight. For my use the meter is adequate.

There is no multimeter that isn't sensitive enough to determine this. However it is usually 24VAC, at least in the US but custom bundled transformer and bell sets may differ.

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

Yes, you can check the function of a diode with any ANALOG meter. The needle should swing only one way as you reverse the leads, because a good diode only conducts (current flow) in one direction. If you switch the leads (while on a low resistance scale) the meter should not "conduct", swing up if it did when they leads were reversed.This has been a good meter for me.

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 would not do that. I don't think it will give you a true reading of the battery condition. I ran a dedicated pair of wires from Positive & negative battery terminals to the meter. I installed a small toggle switch on the dash & broke the negative wire thru it so that the meter only draws current when the switch is on. otherwise it is always draining the battery. Hope this helps.

Yes you can. Just cut the wire and put positive to positive and negative to negative. Source: I did something similar like that before

No, this produces no negative voltage. The "-" terminal is marked to indicate what you would normally refer to as DC ground

Yes, this would be an excellent use for this tool. Be sure to check a known power source such as a receptacle to ensure the tester is working properly.
