Hi Jim,I doubt there is a battery. More likely, just a connection turning the scale on or off.

I bought a Heathkit IM-5210 HV Probe today at a ham fest. No manual... I have not taken it apart (yet) nor tested it. Question: It has an ON/OFF switch which implies it might have a battery inside. Otherwise, why a switch? Anybody know or, better yet, anybody have a PDF of the manual?
