I plug the transmitter in a 120V outlet, 2 breakers give me a constant sound and 1 breaker gives me a solid but broken sound. I tried again and again the result remained the same. Can anyone explain the scenarios please?
Asked by: cdt
The device needs to be "conditioned" by first dragging it across all circuit breakers then touch each circuit breaker individually. Hopefully this helps.

Digital Circuit Breaker Finder is rated 3.7 out of 5 by 329.

I do recommend purchasing the Klein Circuit Breaker Finder "Accessory Kit". The kit included a set of alligator clips so you can attach the plug-in "Transmitter" and then you can find the breaker which belongs to a loose live wire. I used my kit to find a hot wires location to the breaker box. The kit also comes with a screw in plug so you can find, for example a can light location to the breaker box. I had one location at a wall switch which had a unused live wire in the box and was able to find the breaker using using the transmitter/alligator clips in just a couple of minutes. Wish I had purchased this tool long ago. The only negative so far is the on and off switch on the receiver is very sensitive to touch with no positive on/off button. But I can live with that because it shuts off if not used so if it does come on in my bag .. no big deal for how much time it saved me already.

IS IT PERFECT NO BUT WHEN USED PROPERLY IT CERTAINLY DOES IT'S JOB SIMPLE INSTRUCTIONS & BY READING THEM ALONG WITH FOLLOWING THEM YOU WILL DO FINE. HERE WHAT I FOUND * AS PER INSTRUCTIONS ONCE YOU PLUG THE TRANSMITTER IN (THE ONLY THING YOU CAN PLUG INTO A WALL) * IN A NORMAL FASHION LIKE YOU WERE DRAWING A LINE JUST RUN THE TRACER UP THE CIRCUIT BREAKERS (ON ONE SIDE ONLY) THEN GO TO EACH BREAKER AS IF THAT'S THE ONE YOU ARE LOOKING FOR & IF IT DOES NOT BEEP JUST KEEP GOING. * IT WILL LIGHT UP THE ARROW ON THE ONE YOU ARE LOOKING FOR. * I THINK IF YOU GO UP AND DOWN BOTH SIDES THE HIGHER AMP BREAKERS JUST CONFUSE IT SO JUST DO THE BREAKERS SIZES YOU ARE LOOKING FOR. I.E. SO AN OUTLET IS NOT GOING TO BE ON THE 50 AMP BREAKER SIDE SO WHY LOOK THERE. *ON OFF SWITCH FAIL - THERE IS NO AUTO OFF ON THE SWITCH. IT COMES ON IF YOU LOOK AT IT. I WILL MAKE A BOX OF SOME SORT BUT FOR NOW I JUST KEPT THE PACKAGING. SO TRY NOT TO MANGLE THE PACKAGING B/C YOU WILL NEED IT. OVER ALL I LIKE THE PRODUCT SO FAR. I MAPPED SEVERAL ROOMS & IT WAS CONSISTENT.

That's the best way to describe my experience with the Klein ET300. 1. The on/off switch is poorly designed. The slightest touch of the pushbutton turns the unit on with a "beep" and a "trilling" sound -- and any subsequent touch of the button produces a "beep" & "trill". Don't try carrying this in your pocket! 2. Usefulness has been marginal. When it works, it's great. Much more decisive than my old GB Circuit Tracker. However, it's worked on only 1 of 4 panels for me. 3. No storage provided for the transmitter dongle. (I have the same complaint with the GB unit.) Why the designers don't include a simple socket in the receiver for it to plug into, I don't understand.(See Extech and Sperry for the right way to do it.)

The Digital Circuit Breaker Finder did not indicate the correct circuit breaker on most of the circuits in my panel. When it did correctly indicate the correct circuit breaker it also indicated 1 or 2 other breakers at the same time. I still ended up having to turn breakers on and off one at a time to identify the correct one. Just like I did before I spent money for this instrument.

It's easy to use. Located the correct breaker for a series of outlets in the basement within 10 minutes. I'm gonna spend an afternoon mapping out all the circuits in my 90 year old house, correctly labeling the breakers and corresponding outlets/receptacles

And would sometimes light and and sometimes wouldn't light up when I tried to repeat it multiple times. I ended up using a volt meter as a double check, since I couldn't trust the results from the Klein.

I have used this for finding breakers in the last two days in unmarked panels you have to let it learn the panel per the instructions and this takes a little more time.I wonder if it had a sensitivity adjustment if that would make it even faster? Overall good quality I would recommend to a friend.

Rated 3 out of 5 by from Works great It works great but the problem I find with a lot of tools now is they don't have on and off switches so when you put them in pocket of work bag or even your on pocket of clothing it automatically activated reason for the 3 stars a on and off button would be great to keep from draining batteries...
