[QUOTE="Andy™, post: 120047, member: 2012"] any multimeter will be able to give you ohm readings, and would be adequate for home learning, but in the real world it wont comply (must be 200mA current on continuity) for IR testing, much less suitable - you need to test at 500v (or 250 in some cases). your multimeter cant do that, and at the voltage it tests, it wont give you accurate readings. but if you wanted to add some resistors into the circuit to create insulation breakdowns etc, then it would most likely be suitable to give you and ohm reading, and may be of some use. just remember thats it will different in the real world, and it could confuse learning a different method at home [/QUOTE]
