Can this item measure a negative voltage and show a minus sign?

I would say no, as the product description says "Power cannot be reversed, otherwise it will burned the module"

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 , 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.

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

You can try it, worse case just send it back, but I don't think it will work. Maybe you could see if you can mount it on your meter. It's a very helpful tool.

When testing polarized parts, such as a diode. It should only allow current in one direction. When you try to push current through it in the wrong direction it will read .0L, because it wont let anything through. I had to check diodes for a power supply. When I connected it in the correct direction, it read .5, but in the wrong direction, .0L.

It will tell if there is voltage present. Just touch the outermost edge of both sides of the cable to make sure you have voltage on both phases.

Yes, this is a voltmeter, so it will read whatever the voltage is at the time, it doesn't have any memory capability.

You have to find out the voltage going into your home or studio from the electric company or by checking out your fuse box. The incoming voltage amount may be posted on it.

Make sure the polarity is correct. Also make sure there can be no motion for it to detect. These are sensitive units. Good luck!

Put a good multimeter on the out put leads and spin it. you will read DC volts with NO ac COMPONENT. ww

Yes. Select either up to 40A or 400A by rotary switch. Defaults to DC measurements.

NO. You should know you need an oscilloscope, this is a current measuring device and if you don't know the difference, you had best stay out of the circuit panel !

you can purchase an optional AC-DC adapter.it should have an output of three volts with the center negative, and not less than 100mA

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, you need to use a volt meter to find the positive and negative side of the battery.

There is NO "positive" and "negative" in house wiring. Please do a web search on "lamp re-wiring". An improperly wired lamp can give you a bad shock (or worse) even with the switch off.
