[volt-nuts] Rotek 320 AC/DC Calibrator

[Marv @ Home]

Thanks John, appreciated, not sure if they are similar as the unit is 
in transit and not in my possession, its a boat anchor.  Will let 
you'all know the status after a thorough evaluation.  Still doing 
'discovery' and getting as much info as possible.

 From a volt nuts perspective, for other readers, calibrators may 
have very stable references in single digit ppm, and maybe an option 
instead of build your own reference, plus they may come with built in 
KV dividers, precision AC oscillators etc., that alone maybe worth 
the whole kaboodle.  Some are dirt cheap, as low as free except 
postage, others not so.
