    Megger 1kv IR faulty?

    Hi, I have a megger 1741+ that won't perform the 1kv IR test. Everything else on the tester is good but when I press test with 1kv IR settings it triple beeps, that's with the leads not connected to anything (or connected to a circuit). Is there an easy fix for this or does it need sending back...

From that point onwards it would no longer perform either a 2 hi or 3 lo loop test and seemed to...

    Faulty RCD tripping on the button but not via the tester

    What should you do if a client has a CU that is a split board protected by 2 * 63Amp 30mA double pole RCCDs, you took Zs and tested both RCCDs by their buttons before starting work. But on completion of work, one of the RCCDs, when tested via tester, would not trip, the other operated as expected!
