hi i was wondering if anyone can help me, to calibrate a insulation continuity tester on the 3 ohm range to 1 ohm . what can you use to do that and how to make one

i'm not sure but i think you need a 1 ohm resistor or some thing and when you put your tester on the 3 ohm range it should read 1 ohm. if not you adjust

calibrating insulation continuity testers


As a commercial/industrial service electrician, I have seen, used, or at least heard of pretty much every piece of test equipment imaginable, but I have never had to calibrate an insulation tester.(I am assuming you meant an insulation and continuity tester, I have never heard of an insulation continuity tester)

I own an insulation tester (megohm meter) and use it regularly, but to my knowledge there is no way to field calibrate it.

I also own several different types of continuity testers and again, no calibration needed.

If you could post the make and model number of your tester we may be able to help, otherwise I am just confused.

Insulation is about lack of electrical continuity.

If you're talking about a megger, I guess you could wire 10 ea., 10 meg +/- 10% resistors in series and get a 100 meg +/- 3% composite resistor.
If you wire 100 ea. you get 1000 meg +/- 1% resistor.

Ten will cost you 50˘ from this place

but I couldn't find a tolerance spec or max voltage rating (usually it's 500v) on their webpage.
