CM42-MAA101EBE00 Calibration and adjustment
Endress+Hauser 7
2.2.3 Delta zeropnt.
The device determines the difference between the zero points of the last and second-last
calibration. A shift in the zero point does not alter the sensitivity of the measurement. However,
if the offset is not corrected this can falsify the measured value.
As with the slope, you can also define and monitor limit values for the offset. If the limit values
are exceeded, this means that maintenance must be performed on the sensor.
