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?
