Fluke 5520 A unstable VDC output
« on: February 01, 2022, 09:38:46 pm »
Greetings, this is Octavio from Mexico. We are experiencing some trouble with our Fluke 5520 A. For starters, it showed Error 104 Trip Relay and was solved by replacing a 9 volts regulator. Currently, the 5520 A is performing poorly and we are obtaining unreliable VCD readings, oscilating between +- 0.5% of reading, wich for a 5520 A is a lot. Also, when turning off and turning back on the calibrator the reading will not remain stable. Any suggestions?
Does anyone have schematics for this device? thanks in advance.
