Hi. Does anyone have a favorite megaohm meter? I just spent far too long chasing a problem and I think it's going to end up being an intermittent compressor problem. Having a megger probably would have saved me a lot of time on this one.
So, do you like the old-school kind with a crank? Are the new-fangled digital ones what you crave? Any brands to avoid?
Thanks!
I got a digital one made by Megger. Nothing posh, reads with a bar graph and also numbers. From Ebay £30. Does me.
Others swear by the moving needle type as some say you can catch a intermittant short as you will see the needle flick whereas a digital one might not refresh quick enough to show.
Cheers,
Andy.

got the wind up type bullet proof but heavy,got a fluke for ease but i dont trust it!
Avo Megger BM104 iirc. Fixed 500V, because some manufacturers have told me that 1000V sometimes fries the internal motor klixons & not to use more than 500V.
Have been issued & used an Aussie brand (forget the name right now, most of the others would know it) that has the advantage of a locking test button. But it's a bulkier package & too big to be in the tool box 'in case'.
This is the one i use,

I got an old extech digital one off ebay. Works as advertised. Showed me the compressor was toast instantly. Takes 6 AA batteries though and I got to clean out the old leaky ones from the unit. Makes me respect the hand crank ones. Never out of juice and no batteries to leak.
