HISTORY:
This component has been pulled from a wonderful piece of test equipment made by KEITHLEY (USA), the 642 Electrometer. This equipment is from the 1980’s ~ 1990’s era, technically advanced (for the day) and designed to measure voltage, current and charge to extremely low levels (see one of the snapshot photographs from the User Manual)
Why “part out” such an instrument? I have decided to make this equipment an “organ donor” because a critical component is no longer with me, the remote head! To make measurements a wired head is required and without that, the instrument had no sensing abilities.
