Hi Brent!
We also have a PC6-288.1 Surge Tester (great machine!), and have had similar service issues with Hipotronics. I may be able to help. Give me a call.

Hipotronics has been of no help after the person who calibrated it quit the company, so I'm looking for alternatives: - Is there anyone in the US other than Hiptronics that can repair this old beast? - Does anyone out there have a service manual/schematic for the unit (Haefely won't sell them to me).
