I bought one of his 5 volt references about 2 years ago. I have a pair
of Fluke 8800 5.5 digit voltmeters, at least 30 years old and at least
10 years since a traceable calibration. I had temporarily retired them
because they both needed new filter capacitors in the power supply.
I recently needed them for a project so I replaced the filters, fired
them up, connected that little standard to them and....
5.0000 volts on both meters. And THAT, sports fans, is why I buy Fluke
voltmeters! Oh, and the voltagestandard.com dude makes a GREAT little
