Hi guys,I'm getting a 0.00 reading at the mains for loop impedance and fairly low readings on the circuits.My r1+r2 is higher that all the loop readings on each circuit.This has never happened to me before.Can someone explain why?

  • Depends on the make of meter, but I've had issues with Megger 17xx series with loose connections on the input jacks. Using a 3 wire LO current test will give lower readings that 2 wire High current due to intermittent contact.


    not my tester (I'm not the QS on the job, just the guy who knows the connections are dodgy..). Repeated 'calibrations' haven't fixed the fault. It drives me mental
