So what would be an acceptable low cost Meg-ohmmeter? At this point it is more of a curiosity for me. I have a nice Fluke clamp on for the stuff that counts. I have never used a megger and would like to learn.
Out of curiosity what is "stuff that doesn't count"?
Anyway, a nice crank amprobe meger on eBay can be had for $100 or so. The generate a nice bit of voltage with the crank gen and I like the 0 latency of the analog meter.
Without spending $1000 your are not going to get more accuracy.
These are designed to test insulation breakdown.
I may have been confusing the issue in several posts. When I say "Megger" I am not speaking of a megohmeter but a Megger Instruments ground tester. These are used to test the quality of ground fields and read accurately below 1 Ohm
