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.
Sample printout:
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.
