Calibration
evaluation
After calibrating, the measuring module automatically
evaluates the calibration. The evaluation appears on the
display.
Calibration record The measuring module automatically saves the cell
constant in the calibration record. The last calibration
protocol can be displayed at any time with the aid of the
Cal
Prot. function ... in the Cal menu (see section 11.3).
Note
You can automatically print a calibration record after the
calibration. To do so, switch on the printer before calibrating
(print LED lights up green). After a valid calibration, the
record is printed.
