[volt-nuts] HP 745A AC Calibrator

[dlewis]

I see discussions of late on the Fluke 5200A.  'Appears it is widely used 
and available.

I have been fortunate to amass four of the HP 745A AC calibrators;  I 
thought I was getting a pretty good setup for establishing AC references.

What is the opinion of the group of the HP 745A?  Other than heavy, hot and 
loud.  :-)

Once calibrated, both units appear close in accuracy specs.

Does the 20 years between them really matter if they are set up properly?
