For offset and gain correction, arbitrary reference values within the
measurement range can be entered as setpoints. Ideally, it should be a
close as possible to the lower (offset correction) or upper (gain correction)
full scale value.
4. Close the dialog. This saves the calibration instructions directly.
Therefore, it is not necessary to click the [Write] button.
After the calibration, the process values will correspond to the reference
values over the entire range.
The measuring circuits can be calibrated in the same way, independently of
each other.
The calibration process is performed on a channel basis; therefore, before
the calibration process, be sure to select the corresponding channel.
5. Repeat steps 1-4 for each channel.

The "Calculation" menu item shows per channel the formula with which you can
convert the process values.
