Hello

I am in the process of repairing a Fluke 725 calibrator and need a schematic or service manual to complete the repair.

If anyone has a diagram and willing to share it , it will by very much appreciated.

Thank you.

Ernst
 

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.
 
hola miguel, tengo un problema con el modulo de temperatura de un 725, estaba midiendo temperatura y de repente dejo de medir, se quedo como si las tarminales de TC estuvieran en corto, tienes alguna informacion o recomendacion para ver por donde podria comenzar con la reparacion? yo trabajo en un laboratorio de calibracion y tengo mucha informacion de ajustes,reparacion, etc de muchas magnitudes que te podira pasar si lo requieres, solo hazme saber si en algo te puedo apoyar.

saludos

Please, please, please

Colud you send the electric diagram FLUKE 725 , to me ( also dlmoraru@yahoo.com0
I need to know the value of R 131 and R131 .they burned out due to high voltage applied to MEASURE slot

many thanks.......
