7.2 Switching on
Familiarize yourself with the operation of the transmitter before it is first switched on. In
particular please read the "Basic safety instructions" and "Operation options" 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 initial commissioning, the sensor must be calibrated so that the measuring
system can return precise measurement data.
