UNI-T AC Circuit Breaker Finder with Integrated GFCI Outlet Tester AC 90-120V USA Plug + Adjustable Sensitivity Beeper Indicattion+ Flashing LED Light

Finds breaker very well but says I have open ground and I got out my tester I know is good and it say they are fine. The tester part is inaccurate

I ordered this to add to my electricians toolkit. Ive been to houses before to diagnose electrical problems. It can be frustrating when the circuit breakers arent marked inside the panel. So I thought this would come in quite handy. One of those tools you dont use often, but when you need it, it pays for itself. So I tried it out the other day. The outlet had no power. Using the tester, I was able to locate the circuit and it had a GFCI in the panel. I tried the transmitters GFCI test on a couple outlets in our house. The test worked perfectly. Next I tried the receiver paired with the transmitter to locate a breaker in the panel. The first try, I got nothing. I reread the instructions and then double checked the battery. I included a picture of the battery as shipped. I first glanced at it and thought all was good. The battery is shipped wrapped, inside the compartment, but its not connected. You will need to remove the battery, remove the wrapping and plug it in. After connecting the battery, the tester worked perfectly. I tried two outlets and was able to detect their breaker inside the panel. A great tool for identification purpose. The UNI-T transmitter is easy to read. The key is printed right on the tester for reference. I have a similar outlet tester with small LEDs on it. This UNI-T is much easier to see and read, glowing brightly. I tried it on multiple outlets, finding nothing wrong. The UNI-T AC circuit breaker tester and finder is a welcome addition to my toolkit. For the current price of $28, certainly a reasonable price for a tool sure to prove invaluable. Im happy with it and recommend it.

Good

It just trash

GFI shows open ground always, very poor breaker identifier. Waste of my money. I bought the Kline tester, works perfectly. Stay away from this unit.

This device is very easy to use and allowed me to determine a problem with the house wiring in the circuit breaker cabinet. I contacted an electrician and he was able to resolve the problem which could have resulted in damage to appliances and devices plugged into the affected outlets. I dont understand the whole issue but it had something to do with the neutral leads. The symptoms were this device sounded off on multiple breakers for widely separated outlets. The electrician was able to fix the issue fairly quickly and once he finished the device worked flawlessly.

50+year old building. Built on 3 times. 3 rental units. 5 breaker panels. This tool was a life saver for me.
