Hi, I have a Fluke 725 on the workbench too, i have been lookin for a schematic o service manual , but no luck. I have dowloaded information about the ic´s and using some experience i was able to test power supply, relays, and electronics switches of the 725. Mine still in repair because in Mexico is very dificult to get those SMD. If you agree we can pass information about the experience with 725: My first problem was a overvoltage shock, in the voltage reading pins and in the current loop, only the jacks on the right work, a pair of ADG333 suitches were damaged, but the MAX660 charge pump too. By the way use extreme care because of the electrostatic discharge, all the components are MOS.
