6.4 Switching on
Familiarize yourself with the operation of the transmitter before it is first switched on.
Please refer in particular to the "Safety instructions" and "Operation" sections.
After power-up, the device performs a self-test and then goes to the measuring mode.
Now calibrate the sensor in accordance with the instructions in the "Calibration" section.
During commissioning, the sensors (except digital sensors) must be calibrated so that
the measuring system can return precise measurement data.
Then perform the first configuration in accordance with the instructions in the "Quick start-
