Note: Practical example:
GSM level Position
-67dBm Reference measurement outside the shaft

8.3.2.1.2 Possibilities for improving the signal quality
l
Drill a duct for the connection cable of the antenna into the concrete ring on the shaft to avoid the steel
cover
l
Insert the connection cable of the antenna in an existing ventilation or supply pipe
l
Use special types of antennas
8.3.2.1.3 Procedure for determining the optimum position of the antenna
1. Install the myDatalogGauge 3G as described in chapter "Installing the myDatalogGauge 3G " on page
50. During this process, also observe the notes regarding the influences on the signal quality (see
"Typical influences on the signal quality" on page 62).
2. Activate setup mode (see "Setup mode" on page 41).
3. Wait until it is indicated in the list of sites/applications that the device is in setup mode. This is indicated
by a speech bubble with the "Setup" inscription.
Setup mode active
4. Either wait until the speech bubble is hidden again (setup mode completed successfully) or until the
background colour of the speech bubble changes from white to red (problem detected). In both cases,
this can take up to 8min. .
Setup mode completed successfully Problem detected
5. Open the site settings (see "Site configuration" on page 79) and click on "Setup data" to display the
GSM level determined during setup mode.
