Yeah... I've been using my moderately cheap meters with no problem, waiting
for the motivation to dig into the Fluke.   Glad this message came along, I
have missed using it.

I still have some of the Caig stuff, from back when they called it
"Cramolin," but would be nervous about applying it to the Zebra strips.
Especially given the long intervals between needing repair.  In other words,
it isn't enough of a pain to justify the possible risk, in my mind anyway.

Can someone tell me what kind of conductor material is used in the Zebra
strips?  Some kind of carbon fiber or powder, maybe??

Robert,
I had a Beckman DMM in the very early 80's... HD-100 maybe?  It was the
first bright yellow "hardened" handheld DMM, as I recall.  The case halves
were o-ringed, and it was rated for a multi-foot drop to concrete, and
immersion in water.  It gave me many years of good use in a tough
environment (automotive electronics repair).  Eventually the LCD developed
the opposite problem as the Fluke -- the digit segments became dark even
when the meter was off, and they gradually bled until the whole display
looked like it was filled with black ink.  Would that indicate a change in
the spacing of the glass inside the LCD, or...???  Very nice meter, though.
