Note
You can automatically print a calibration protocol after the calibration.
To do so, connect a printer to the interface according to section 4.7.2
before calibrating. After a valid calibration, the record is printed.

Calibration evaluation
After the calibration, the measuring instrument automatically evaluates
the calibration. The asymmetry and slope are evaluated separately.
The worst evaluation appears on the display.
