I have never used it and haven't taken the time to learn to use it. I would be interested in learning how to check the accuracy of the standard cell. What voltage level should I hope for?Great instrument. Used one for quite a few years when I worked for L&N from 1975. It could measure temperature signal from thermocouple and output thermocouple emf to recorders,indicators etc. I wonder how accurate the standard cell in it would be now. I don't know if they are still available.
The glass bulb is there and the electrolyte is crystal clear. I'll measure the voltage tonight.From the dim recesses of my memory I believe it was a Weston Standard Cell. A glass "H" pattern thingie with some sort of mercury electrodes and some sort of liquid electrolyte. Puts out a fixed voltage at about 1.something volts over a wide temperature range for a long time as it is unloaded. Just used as a voltage reference. I can't recall how to zero the dvice now but I'm sure its in the manual.
