[QUOTE="Bruspark, post: 519766, member: 20106"] The thing is that a decent MFT or multimeter will have been checked or even calibrated severalplaces in the ohms and Kohms range while a megger etc was probably checked at 1 or 2 Mohms If they all say 10 Megs I wouldn't worry, but if an insulation tester says its 0.03 Mohms I would not be relying on that as a 'calibrated and precise reading' In fact the spec likely says +/- 1 count at least on top of +/- 5 or 10% [/QUOTE]
