3. Wait until it is indicated in the list of measurement instruments that the device is in setup mode. This is
indicated by a speech bubble with the "Setup" inscription.
4. Activate the display by briefly pressing (approx. 1 sec.) the solenoid switch.
5. During normal operation, the status indication in the centre of the display should now alternate
between the current gas measurement value and the current setpoint [mA] for the BLE mA Link .
Based on the currently displayed value, the type designation and serial number for the relevant module
are shown in the upper section of the display. If BLE paring of the data logger and BLE mA Link was
not possible, error "E15" is shown on the display.

6. The following steps are only necessary, if you simultaneously want to test the setpoint output.
7. Add a suitable measurement instrument (e.g. milliammeter) to the current loop and compare the
measured value with the one shown on the display of the data logger.
