About the highest I ever go on a regular basis is the 200 volt line on a CRT set or the Vs voltage in a plasma. I might just pick up a Simpson of some variety or other though. The 260 XLPM looks pretty good - I like the extra ranges compared to a regular 260 and I must confess that between my advancing old age and laziness from using a DMM the past 20 years, simple precautions I learned in tech school need to be relearned. The other day I inadvertently put my Fluke 8800A probes across a 50 volt DC source while on a 200 ohm resistance setting. Didn't seem to damage it, but boy, I sure gotta watch that stuff. Hopefully the relay protection on the Simpson would prevent damage from any such stupidity. Mark Z.

Far better to use specials for EHT which include an attenuator. -- *What do little birdies see when they get knocked unconscious? * Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound.

I need to be able to use conventional banana types. Mark Z.

Only on extra low voltage, I hope? ;-) -- *Seen it all, done it all, can't remember most of it* Dave Plowman dave(a)davenoise.co.uk London SW To e-mail, change noise into sound.
