Hi Frank,
I also interested with the paper and paper from spreadbury and deaver if You
don't mind
Thank You
yes I have this paper, size is too big, so I'll forward it to you directly.
The patent to this 7000 standard is UK patent GB 258 356A, about
removing of hysteresis of the LTZ.
Hello!
I would like to measure insulation resistance of some defective load cells.
The measurement should be done with no more than 50V and the full scale
reading should be >=5Gohm. Accuracy of +-10% is enough (in fact it could
suffice just to check if it's >=5Gohm or not).
I have not been able
50V across 5GOhm is 10nA. Put a standard multimeter's 10MOhm input in
series and
you have 10mV per nA reading. Anything below 100mV is pass.
My 2 eurocents.

Also, quite a few of the Fluke portable and handheld DMMs from the
last 35 years or so (including the faithful old 8050A and the
