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.

I don't need to start flipping breakers until I get the right one. This thing works, and no guessing which breaker matches the outlet. Really neat product.

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.

Moved it to another plug in that circuit and even reversed the transmitter to see if that changed anything. It didn't. Maybe mine was defective but it did pick up and correctly identify two circuits I had selected to test best case scenario given their overall relatively close proximity to the breaker panel. Unfortunately, the one circuit I actually bought it for did not register at all. As such, I cannot give this device a positive review. Two stars because it did actually identify the two test circuits I knew were short runs. For what it's worth, the circuits were live when I tested them (transmitter red light was on) and I scanned the panel perpendicular twice per the instructions. Even after power cycling the receiver and re-scanning the panel. I'll be trying the competitor's product in hopes it works better in my environment.
