Well, after an hour of warming up I'm getting calibration errors again...

Lowpoint 0.01V RMS (10mV)
Highpoint 0.2V RMS (200mV)
Range 0.2V

Confirmed the input values with the DSO and a calibrated Agilent
multimeter, but after entering these values the meter refuses to
calibrate. Display shows "ERROR". :(

So it looks like I'm back to the original fault...
