Review on 🔌 Enhanced Extech CT20 Green Remote and Local Continuity Tester for Improved SEO by John Love

I was able to check the continuity of the circuit and identify the wires in the circuit. The board is a great time saver. When the tester arrived it didn't work. I loosened the screw and opened the battery compartment. I was a little upset as the battery wasn't installed and I didn't see it in the box. After I finished the day and put the tester away, I found a 9 volt battery in the storage bag. I didn't even think to look there.
