7.2.4 Calibration report
In the pH and Conc(direct) modes a calibration report can be produced
after a calibration has been carried out. Under PARAMETER/calibra-
tion parameters/report you can define whether this report is to be
produced automatically after the measurement. You can also choose
between a short version containing all the important data and a long
version which additionally contains a plot of the calibration function.
