Right think I have enough of this machine thinking very hard and long about going back to Fluke.
Can anyone tell me a reason for me getting a calculated Zs: Ze+(R1+R2) of 0.68ohms then getting a measured Zs of 0.94ohms which is considerable higher than my calculated Zs, now I know it still passes and is within limits but this discrepancy does not happen all the time plus I never got any discrepancy with my fluke so does someone who has used a Megger 1700 series got any idea.
Doing the Ze on high current L-L L-N for none RCD protected circuits.
Doing the Zs Measurement on L-PE so it doesn't trip the rcd.
Now I know I can use links and bypass RCD but surely you shouldn't have to do this to get a correct result as it is a no trip test and the pam say's switch to L-PE and test on Terminals L1 and L2 Phase and Earth.
