LCR Cal Test PCB

[KungFuJosh]

My old version (I think V1) of the Cal Test PCB went up to 1GΩ so I was able to test 100MΩ on there. It shows about ~80MΩ, so 20% less than the nominal value. Whether it's actually off or not, I don't know, but it does tell us that only the 1M and 10M ranges are goofy.

Looks like the 100M range is probably ok on the 3532-50. At 1kHz, the IM3570 is reasonably close.

At 5Hz the IM3570 reads it verry niiiice.
