The trick is to get one that works, reliable and doesn't drift around. This is a good one. Not bad for these older units.
They have ranges from 1v to 1000v full scale in both ac and dc as well current 100ua 5 amps basic accuracy is. See the calibration sheets in photos showing testing done. These are a lamp and photocell couplet - hard to find, but new one is now installed.
Hp 6920B meter calibrator - refurbished and calibrated a these calibrators are great for dams without spending tons of money on basic functions. I have been through this calibrator and re-capped it as well checking all the resistors for correct values. Most are goofy.
After burn in and adjustments, this calibrator meets factory original specifications. Power cord included.
