Hi all,
Recently, when needing to test earth fault loop impedance on a circuit with a RCBO/RCD my tester just reads >2000 for evert test, even when I know the R1+R2 and Ze are fine and when added together would be well within limits.
Is there something I can do to fix this or is it time for a new tester? (it was bought in 2010) My last calibration showed no problems, but this started afterwards.
Everything else tests as normal.
