[QUOTE="Andy™, post: 519751, member: 2012"] both are testing continuity / resistanc. there pretty much the same thing. IR youre not expecting low readings hence the high readings and always in Mohms. its also at a higher voltage. continuity you want to check the lower resistances, for this you also want current (200mA flowing required) you could do an IR test for checking extraneous or not, however im not aware of any MFT that have a Kohms scale unless the resistance is in the Mohms, it wont be any help. reading of 0.00 could still be well over 22K [/QUOTE]
