6.5 Calibration of All Amperometric Measured Variables

WARNING!
Danger of incorrect metering
This can result in hazardous incorrect metering
During initial commissioning, the measured variable and the measuring range of the sensor must
be set prior to calibration. Refer to
Measuring Range " on page 37
