Fluke 8600A will not show zero on low VDC ranges

Aug 03, 2005 1 Replies

three Fluke 8600A multimeters will not show zero volts when measuring VDC on the lower ranges. On the 200mV range it slowly increments until it overranges. With shorted inputs, it is close to zero, about 0.5 to



3 mV, but never zero.

All suggestions more than welcome.



Thanks, Anders J


The slow incrementing sounds like a charging capacitor, My guess is you have a open resistor or bad solder connection that is allowing a cap to charge and now your dc voltages in the meter are not what they should be. You might want to send it into Fluke. You can have a peek inside if you want, heat up the solder connections on the circuit board, look for open or burnt circuit traces...

Good luck...
