Advantest R6581T 8.5 Digit Multimeter Repair Part 1

I begin the repairs to an Advantest R6581T 8.5 Digit Multimeter which I picked up for a reasonable price.

The R6581T has a dim display, clicking relays on some ranges and shows overload on the display even though there is no overload present.

I replace the battery and do an internal calibration to fix the clicking relay and overload display issue.
