12 Wait for the measurement with stability control to be completed
or terminate the stability control and take over the calibration
value with <ENTER>.
The calibration display for the next buffer appears.
13 If necessary, terminate the calibration as a two-point calibration
with <M>.
The calibration record is displayed.
