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 O&S manual from K04BB but I don't know how similar it is to the 1082. Can anyone comment on what the differences are? Thanks, Randy Evans randyevans2688@gmail.com

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. -Chuck Harris Randy Evans wrote: > I have a Datron 1082 DMM that just recently stopped working.

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.

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.

Randy I would say from my experience with Datron there is about 90% chance the battery and recal will solve the problem. I would modify the battery with a coupe sets of leads that are long enough so you can install a new while the old battery is still in circuit.

Tom, I would think with 0.08 VDC the battery is dead and all the memory is gone. Do you think it would make any difference if I paralleled the leads with a new one? I don't have a parts list to know what type the battery is so it's going to be a challenge to find a direct replacement. Wish I had a manual.

Sorry I wasn't clear. I think the errors you are experiencing are because the memory battery is gone, so it won't matter now, this is for saving the cal data during future replacement to avoid these problems again.

The schematic of the Datron 1071 DMM seems to be very similar to the Datron 1082 but I'm sure there are differences. Unfortunately, I have not been able to locate the 1082 Service Manual with the parts lists and schematics. The 1071 manual does have a similar or identical battery but I can't find the part number in the 1071 parts list. Does anyone know the part number of the memory battery in the 1082 or 1071, or the characteristics; e.g., voltage and A-H rating?
