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?


Thank you,
