11.1.2 Buffer sets for calibration
You can use the buffer sets quoted in the table for an automatic calibration. The
pH values are valid for the specified temperature values. The temperature
dependence of the pH values is taken into consideration during calibration.

Starts the control calibration with QSC buffers.
This menu item is only available if an initial calibration was
carried out with the connected IDS sensor.
