I believe the voltages are correct but I have no schematics or
troubleshooting instructions to confirm. I do see what looks like a
battery in the memory section of the 1082 and it measures 0.08 VDC. Not a
good sign. I am really hoping someone has a Datron 1082 Service manual
with schematics that they can steer me to, preferably a soft copy so I can
better troubleshoot the unit. It might just need a new battery (plus a
re-cal) to get it going again but I hate going blind.

As with many products of this age the tantalum caps are a common point of
failure in the 1082.
Although this current problem sounds like a memory battery.

Just in case you haven't yet: Always start any investigation with
checking the power supply for voltage and ripple. Test the main
electrolytic capacitors for capacitance, and ESR.
Nothing in the unit's self testing ability can be trusted if the
power supply is putting out large amounts of ripple, or is at the
wrong voltage.

I have a Datron 1082 DMM that just recently stopped working. When I
power
up, it gives a FAIL message on the front panel. I found a flowchart
in
an abbreviated servicing manual that indicates it's from a failure of
the
Check for uncorrupted calibration store. I Assume this likely means
the
cal tables are corrupted? Unfortunately, I don't have sufficient
information (e.g., schematics) to do any further troubleshooting. Can
anyone help with a complete servicing manual and/or further diagnostic
help?
I did download the Datron 1071DMM OS manual from K04BB but I don't
know
how similar it is to the 1082. Can anyone comment on what the
differences
are?
Thanks,
