    Along with the Martindale proving unit I have the Martindale voltage indicator that I bought at the same time, it gets used, but not daily.


    If you isolate something like a consumer unit or distribution the input terminals stay live, so checking the tester is easy using those terminals.


    I am more concerned about identifying false positives, when the tester indicates the voltage has been removed, but is still there. Just because you have followed the correct procedure and have had the correct indications doesn’t mean the voltage is no longer present.
