8. Analyse the fill level values determined during setup mode. If the displayed values 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 fill level determined by the BLE Gauge and the reference
measurement and enter the difference in the input field for the "Trimming" parameter (see
"Measurement channels" on page 41). As the "Trimming" parameter is added to the
measurement value of the BLE Gauge , a negative prefix must be set for the "Trimming"
parameter if the determined fill level value is greater than the reference measurement (see
"Additional explanation on the zero point adjustment and installation height of the pressure
sensor" on page 42).

mode.
9. Activate setup mode again if zero point adjustment was required. During the initial connection
established during setup mode, the changed configuration, i.e. the new "Trimming" value, is first
transmitted to the data logger and then to the BLE Gauge .
10. Wait until setup mode is terminated and then compare the determined fill level values 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.
8.4 Testing communication with the device
8.4.1 Testing communication between the BLE Gauge and the data logger
Note: A detailed explanation of the operation (connections, activation module, solenoid switch,
display, site settings) is available in the manual of the relevant data logger.
1. For the site that is connected with the required logger, activate the required measurement channel in
the "Measurement channels" configuration section by selecting the mode and specifying the serial
number of the BLE Gauge (see "Measurement channels" on page 41).
Note: If you have purchased the BLE Gauge and a compatible data logger (e.g. myDatalogGauge 3G
ATEX) as a set, the serial number of the BLE Gauge is already saved in the memory of the data logger.
In this case, it suffices to select "Automatic" mode. The saved serial number is displayed in the input
field for the serial number, although it cannot be changed.
2. Enter the installation height of the pressure sensor in the input field for the "Sensor Offset" parameter
(see "Measurement channels" on page 41).
