I suggest a Megger MIT 420. I got rid of my fluke 1587 for it. I truely like it much better and wouldn't hesitate to buy another in the future.

Megger is the manufacturer of Insulation testers know around the world. When You "MEGG" a compressor out is slang for performing an insulation test since Megger was the first of its kind available.

AEMC, BK Precsion, Gossen MetrawattFluke/Amprobe all makes great insulation tester. Megger would be choice over Gossen Metrawatt.

Dump that Supco POS....Get a real insulation tester!


(If not made in the USA, Germany would be my next choice)

you would need 2 meters that can measure volts and amps and save the maximum value. a little more complicated but it would work.

Which part wouldn’t work on start caps? The “10,000 uF” part or the “while operating” part?

Also you can check capacitors with a volt meter, amp clamp, and a calculator

Same here. 1587.
Werks for me. Plus it doubles as a decent meter.

If the Fluke 1587 did mfds I would get it and I would only be carrying one DMM on the job.
So dont be cheap.

I quite buying Supco about 20 years ago. It’s all crap.

It didn't have a scratch on it and still had the plastic screen protection on it. Only thing is the canvas case it came in smelled like cigarettes. Possibly a clue to his untimely death.

I told him it was worth much more. He said he knew but had a bunch of things to sell and the family just wanted it done quickly without much effort.

Anyway, great megger if you can find one for a good price. I just did a nationwide search for one on Craigslist. There are a couple available for under $400. One in Seattle and one in Texas if anyone is around those areas.

Sorry. Texas is big. One in Mcallen Texas and one in Dallas.

Also one for $350 in Sacramento.

Yeah I would be sceptical of people offering to ship items on CL..I would almost bet he would not have trust you to receive the item, inspect then pay..But everyone once in a while you will come across people that will do the right thing..Glad it worked out for you..That's a killer deal.

I have this one. Been great so far.

I have used an Amprobe AM-45 for many years. Good quality, accurate, but only goes to 1000 volts. Reasonably priced. Has some features for documenting trends or just to store into a file.

I’ve used the analog hand crank for years but it’s hard to get a true megaohm reading.

Another vote for the 1587 here.
