Is this sensitive enough to allow me to determine the voltage on my doorbell wiring (16 volt vs. 10 volt vs. dead)?

Yes! My son used it for a science project that measured the amount of electricity fruit generated and it worked wonderfully.

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 know it is a line voltage as I have it installed that way. Not sure if it can do low voltage

This is a simple Volt Ohm Meter. It works, and was quite cheap. I use it for small projects like testing battery status, but it might work fine for your task. Obviously there are many available at Amazon that are of much higher quality, but the price will be more. I would expect you should be able to test areas of your circuit to see where current is still being applied when the switch is off. Do take notice of the ratings for what it can handle.

You can but it will activate the circuit because it's probe voltage is too high, so it's really not meant to. If you want to do in circuit measurements get a dedicated ESR meter. The ESR function on this device isn't really very accurate anyway, it's mainly useful for transistor testing and LCR.

Hello, I have no idea, was just curious about the item and thought I could use it to possibly track down a wall switch that goes nowhere in our house. turn off all breakers but the circuit the switch is on and check for a signal thru the wall with the switch on and follow it, have not tried yet. Just checked around a few wires and it does sense the electricity. I think the deal on it detecting cameras is that you can see the infrared with it or something. Have not had time to really check, it may just be a barely useful gimmick. But I hope I can trace the wire. It may make a cool kinda selective sensitivity signal tracer.Peace!

HI Visa, need a bit more info,..this instrument can tell you if you have power, if your neutral is connected and if you have a short circuit. If you need to know how many circuits there are in a space, count the circuit brakers. If you need to know how many receptacles are on a circuit, shut off a breaker and see what is live or not and you'll be able to quantify them. Have fun, Tom

I don't know. I replaced my old rusted doorbell and intercom. This one was very similar looking to my old one. As I recall it was a very simple wire connection. I think the size is critical though.

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.

It should work fine. It's a simple two wire sensor that just breaks the circuit.

Not really. Its not designed to do so. It may but there is no way to tell if it is wiring or something else. The instructions give a warning that what it detects could be a stud, pipe, wire or other objects

See if u r too close to phones/appliances, or if a computer is on same electical circuit. Very sensitive!

Not sure...but as a suggestion your wasting your money if using it as a door sensor...

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.

This is for 12v and not for house current. You'd be better off getting a motion sensor at a Home Depot.

It can not be powered by the doorbell transformer; it requires 6v DC at 1A I believe, which is included in the package. The problem is how in the world do they expect you to connect this in a normal home installation? The wire attached to the adapter is way too short to be useful. I just decided to use batteries.

My house is old with wired front and back doorbell buttons. This unit works fine when wired to existing doorbell system.Frank

No, it is 9V, I am sure about that.The polarity is what I doubt, but is easy to check. If you pug it and the light does not turn on, it is the other choice.You cannot damage it by connecting it inverse.
