Detect activation power
Follow the steps below to detect the activation power:
1. In the "Settings - Activation power" menu item, select the connected antenna and click
the "Start measurement" button.
2. In the "Min. power" column of the transponder list, you can see the required activation
power. The value "Min. power" of the transponder last selected in the transponder list is
automatically transferred to the "Accept power" box with 2 dB added.
Note
Optimizing the radiated power
The value entered automatically in the "Accept power" box corresponds to the minimum
value with which the transponder was identified by the antenna (Min. power) plus a power
reserve of 2 dB. This value serves as a guideline and you can adapt it. To be sure that
the antenna reliably detects the transponders regularly, we recommend that you accept
the automatically adapted default value.
