[Boatanchors] DC Voltmeter Calibration

[David C. Hallam]

I obviously need to calibrate my DC voltmeters.  I was setting the 300 
VDC B+ on my signal generation after some repairs.  I used 3 voltmeters 
and got a spread of 45V among the 3 of them, low 285V and high330V.  The 
low was a VTVM and the high  DVM.  What is a good standard to use that 
won't break the bank to acquire?  I used to have some mercury batteries 
but they are a no, no any more.

There are two possible outcomes: if the result confirms the hypothesis, then you've made a measurement.
If the result is contrary to the hypothesis, then you've made a discovery.
