hi , my newly calibrated meter seems to work fine but I seem to be getting really high results for pfc,quite often well over 6ka,Ze readings rarely over 0.03 ohms, most of these tests are on boards in high rise flats,would all the earths from each flat cause a really low ze reading and high pfc results? should I really be changing every breaker to 10ka breaking capacity breakers?? has anyone had the same observations? my meter is a megger multifunctional tester,about 7 years old now.
