Bench Multimeter

My ancient handheld Fluke 8020 has a conductance range that can give sensible results up to 100M ohms or so. Bought from that place that in the arches at St Pancras station years ago. Used to hold mega testgear sales. I think it cost me £50 back around 1981. Seemed like quite a lot but it was very good value.

If I need to measure high resistances I'll use my EHT power supply. Set up 500V or 1kV with a DMM and measure the current.

If i measure very high resistance values the DMM becomes a 10 meg shunt with a volt meter of infinite terminal resistance across it. I do check with another meter just to make sure of what is between the terminals as some are 11 meg.
A Megger will supply normally supply the voltage for me.

Thanks all
lots of food for thought.....hmmm

Bit late to this thread, but if the aim is to service valved gear (TV's, radios etc) the voltages were normally measured using a meter such as an AVO 8, which was 20,000 ohms per volt. So although I have several Fluke meters, and a couple of ridiculously accurate 19" rack size Datron 8 digit meters, I also have several AVO's.

Craig,
Never too late - I'd forgotten I've at least one AVO 8 in my garage.

I’m interested in a Fluke 45........I think the chances of buying one for £80ish may be a long shot.

whats a reasonable price to pay for a Fluke 8050a - any thoughts?

Thanks

Unfortunately, postage is double the cost of the meter.

Not to mention the Customs charges and RM's punitive rate for collecting it ...

Apart from a Uni t t61e (£36) I bought a Fluke 8010a for £20 plus p&p... I'm not sure if this overpriced although it does have a returns guarantee if if not fully working.... Overpriced??
