how lowest ac volt can be detect with no contact? I'm looking for low to 3-10 v ac

I don't think it goes below 30v ac as with most non contact sensor do but I haven't tested it that low. I'll update if I test it that low.

I don't have an answer for that since I have only used it for house voltage. If I can find a 3-10vac source I will test it for you. but off the top of my head, I can't think of anything I have that I can use. sorry.

I'm no GC but I think low voltage is fine so I'd say yes. I'd ask a pro though.

You can check voltage , but u can't do a load test to confirm battery condition !

Yes. The minimum ratings are lower than that, as I recall. What does the effect 9v plug input say?

I tried other non contact testers and they tend to give you inaccurate warning. e.g. if you have a neutral carrying current because there is incorrect splicing somewhere else, it will give you a wrong signal unless you separate then far apart to test them individually. This one is pretty accurate.

Yes, I just tried it and it works but since those batteries are 3 volts it is hard to know if it is reading it right. It "pegged" out a new battery and I suspect that it will tell you if a 3V is very weak or dead, but not "low" since a "low 3v" would probably still produce more than 1.5v. By the way, this tester has already saved me it's cost in batteries I would have otherwise thrown away.

go to Ebay type 921 LED AC miniature and you will SEE many vendors , remember it has to be 12 volts AC not DC to be able to work to standard low voltage systems.

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

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 negativeVolts.

The voltage is low, but be careful not to touch wires to each other so that no damage occurs. Cap them or tape them as you remove them. I don't think you can easily turn off power. Also, call your alarm company before you do this to not cause an alert.

Seems like a simpler answer is in order:1: These work for AC, not DC detection.2: When set to a lower voltage detection, they become sensitive and it's hard to accurately identify a source if there is more than one possible source. For example, detecting a hot ground in a standard wall outlet would be difficult because it will trigger just being close to the outlet.

It is not low voltage. I already had the post, so I can't answer that portion of your question.

Only needs 12 volts for lightning. Will read temperature without the 12 volts.

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

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

It is a very low current device - I put in a 10 amp fuse for an automobile installation
