The “Upper scale value” is assigned to the "Upper calibration value” (calibration
offset in this case). This calibration data must now be transferred to the
instrument; if required it can also be saved.

Measurements using a potentiometer
Calibration is necessary in order to specify the relationship between the electrical
signals measured by the connected sensors and the measured values to be
displayed. A two-point calibration procedure is used here. Normally the sensors
have a test and calibration certificate containing details of the electrical signals.
The typical certificate might look like the example shown below, where the most
important values are labeled.
