Carrying out a QSC
control calibration
A QSC control calibration can, e.g. be useful if the sensor evaluation noticeably
changed (after some normal calibrations).
You can carry out QSC control calibrations at greater intervals than normal cali-
brations.

1. Open the menu for measurement settings with <ENTER>.
2. In the QSC menu, select Control calibration with <><>.
The calibration display appears. AutoCal QSC-Kit is displayed as the
buffer.
Exclusively use the QSC-Kit for the QSC calibration. If you use other
buffers, you will have no valid QSC control calibration.
3. Follow the user guide.
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.
