[volt-nuts] Calibration Device

[Marv @ Home]

As digits rise, applications are less 'general', but these meters at 
the outset were mostly for labs, not for servicing.  Work in 
instrumentation: sensors, transducers etc., can use uV precision 
foremost, accuracy preferred.  A diff DVM is ideal but not necessary, 
a sensitive DMM is a cheaper substitute.
