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.

Let me start by saying this unit works great if you use it correctly and follow the directions. It would at best identify two breakers side by side as the target but I'm fine with that...it's better than having to test all 50 breakers to find the one you need! I agree with the reviews about the on-off switch being much too sensitive, but there is an easy fix! Take a small o-ring and insert it under the lip of the switch, this secures it from being turned on in the tool bag but still allows regular operation (see photo attached) This idea cures the problem and makes this unit worth the money.

Rated 5 out of 5 by from I don't know how this could be easier to use Looking at some of the reviews I was a bit nervous but I figured I could always return it if it didn't work. I followed the simple and short directions plugged the transmitter in the outlet and passed the tester over the panel twice and it found the correct circuit every time. Some reviews have complained about having to re-calibrate for each circuit, I figure the 2 or 3 seconds necessary to do this is much less time than I would spend walking across the house to see if I had the right circuit. Also the tester comes with a battery so it is ready to go right out of the box. I only wish I had purchased this sooner.

Rated 5 out of 5 by from Works Great!! Works great for tracing which breaker goes to which outlet!! I had read some of the "negative" reviews and had some doubts, but bought it anyway. I found that it easily traced even to breakers that were "doubles" (two breakers in one slot). Pointed to the side of the breaker in the doubles exactly correct. Perhaps the trick to making it work as well as it did for me is to do the "learning" scan several times before you finally determine the right breaker. I scanned the breaker box 3-4 times and after that it showed the correct breaker 100% of the time. Very impressed with how well it works...the negative reviews in most cases must be operator error!! One use and at the price, it pays for itself!!

Rated 3 out of 5 by from Works as described. I work in refrigeration, picked this and the accesory kit up to help find the breaker for a fan circuit I needed to work on. There were six breaker boxes I had to scan, and found out through trial and error that the scanner needs to be reset between panels, this was not stated in the instructions or I would rate it four stars. If this would also work on 208-230v I could see it being a very valuable tool to me, 120v will limit its usefulness in my field but I think I will be glad to have it on my truck.

Rated 2 out of 5 by from Better tools on the market Bought this to use in the data center where I work. Had almost 1,000 circuits to test and verify that they were labeled correctly. I gave up after three attempts to locate a circuit that was closest to the breaker panel. It rarely toned on any of the breakers, and if it did tone at all it would tone on more than one breaker on each side of the panel. I brought in the circuit finder that I bought for my house which is made by Ideal and it worked flawlessly... plus the Ideal was a few dollars cheaper. Also, I didn't care for the rubber sleeve that covers this thing. It does not allow the toner to glide over the breakers with ease.

Rated 5 out of 5 by from worked as promised I purchased this tool to trace a circuit so I could shut it off to replace a burned out exhaust fan. I have a commercial building and I didn't want to start trying to turn off breakers since some circuits were for servers and computers and testing equipment. A electrician friend said these testers don't work, and don't waste your money!. I bought it anyway At the same time I purchased the accessory kit with light socket adaptor and alligator clips. I attached the alligator clips to the live wires and went to the panel and the tester went off when I went over 2 circuit breakers. Of Course, neither were labelled! I turned one off and it didn't kill the power. In turned the other off and it was the right one. This saved me a lot of headaches. I would recommend this tester.

Rated 4 out of 5 by from Works quite well, if you follow the instructions and apply some common sense It is important to do the calibration scan first and then do the second scan to identify the correct breaker. There could be some ambiguity with breakers that are part of quad breakers with 2 pole circuits. Also, if more than one breaker is detected, it is quite simple to turn them off one by one to zero in on the correct one. On the whole, I am happy with the device and think it is a good value for the price. The companion kit is quite useful for use with light sockets and bare wires.

Rated 5 out of 5 by from It's a professional's tool and requires good understanding of electricity in the home. This device is a professional's tool. But, purchasing, learning to use it and using it is far less expensive than hiring an electrician to the do the same thing with the same tool. The tool works fine. I am using the tool to build a complete electrical map of my house, prior to issuing a request for bids to perform major electrical work on the older portion of my home.
