Hickok 600A Calibration
#15

(04-13-2016, 02:38 PM)Steve McDonald Wrote:  I don't use calibration tubes. I made a a 5mA. transformer I use as a current source. 5 mA. corresponds to 1000 mhos on your meter. The most important part of calibration is to make sure the tested tubes are tested at the proper voltage.

This is a good calibration procedure (too).
