It is my understanding (and AFAIR this is what the manual says) that normally no calibration is needed. I recall that moving from Firmware 1.21 to 1.22 (or 1.23) you had to recalibrate the inputs by means of the autocalibrate function (see page 82 in the manual).
Proper manual calibration requires a decent voltmeter. Your average 20€ (or so) multimeter is not sufficient.
Kind regards,
Michael
