David: Sounds like you got a good find. Clean, batteries hold a charge and has been updated by someone. The lithium batteries are probably the power for the modification that solves the problem that the Mercury Battery for the Reference Supply being "unobtainium" anymore. I have a pdf of the modification including schematic. I can send it to you by PM if you are interested.

I have never used one of these so I put it on the bench, opened it up and inspected it looking for leaks primarily. EVERYTHING is spotless. Fluke factory cal stickers everywhere.
