Hi,

All my 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

Are you near an RF transmitter?

That sounds normal. On the low ranges the input impedance if very high and it will pick up stray voltage easily. With inputs shorted there can be a small offset.
