13. If the calculated average value do not match the ones of the reference measurement, the zero point will
need to be adjusted. To do so, calculate the difference between the calculated average value and the
reference measurement and enter the difference in the input field for the "Trimming" parameter (see
"Measurement channels" on page 83). As the "Trimming" parameter is added to the measurement
value of the BLE Gauge sensor module, a negative prefix must be set for the "Trimming" parameter if
the determined average value is greater than the reference measurement (see "Additional explanation
on the zero point adjustment and installation height of the pressure sensor" on page 84).
14. Trigger the synchronisation between the myDatalogGauge 3G , DeviceConfig and myDatanet server
again to transmit the changed configuration, i.e. the new "Trimming" value, to the myDatalogGauge
3G and subsequently to the BLE Gauge sensor module.
15. If a zero point adjustment was required, repeat all of the steps from step 8 "Wait until some
measurement values have been recorded".
16. Then compare the calculated average value of the fill level with the reference measurement again. If
the values are still not the same, complete the zero point adjustment again.
Note:
The current value of the "Trimming" configuration parameter must now be taken into
consideration when calculating the difference between the determined fill level and the
reference measurement.
