1962 Montgomery Ward C cell battery test

After getting the VTVM working, I was asked if it could then be used to test this early 60's C cell battery.   See the video below for the results!!

Heathkit VTVM Turn up and test

My VTVM that I needed for work with Tube amps and antique radios arrived in pristine condition.  After an inspection of the device and testing of the tubes, a calibration was done and It works perfectly.
