2. In the QSC menu, select Control calibration with <><>.
The calibration display appears. AutoCal QSC-Kit is displayed as the buf-

Exclusively use the QSC-Kit for the QSC calibration. If you use other buf-
fers, you will have no valid QSC control calibration.

The calibration is carried out like a normal three-point calibration. As soon
as the three-point calibration has been successfully carried out you can
decide whether to accept or discard the calibration as the QSC control
calibration.
