Date/Time & Non-Volatile data on 5820A
Looking at the Fluke 5820A Scope Calibrator I see nothing in the Service Manual about renewing a battery that maintains the date and time.
The 5820A does keep date and time when it is turned off, this means it must have a battery somewhere. Whether it is a standalone battery or a timekeeper module (like MAXIM), these will eventually need replacement. I'm surprised Fluke does not document this in the service manual.
I have had my 5820A completely apart (except the keyboard) to correct other problems and I have not seen a battery or a timekeeper module. Does anyone know where the data/time is held in the 5820A?
