Hi,
I purchased a Fluke 8808A and everything appeared to be ok.
Just sent it off to be calibrated, and now when open-circuit the volt meter drifts (DC) by around 0.2 mV/s initially and slows down around 10mV to around 0.001 mV/s like charging a capacitor. Final resting place seems to be about 20 mV after 30 mins.
Is this something I should be concerned about and would this be caused/fault by the calibration house?
Thanks.
