8.5.4.18 Manufacture parameter - calibration of the antenna
During the calibration the corresponding bit is set in the system status (TxPDO 1).
For the voltages Us1, Ud1 respectively Us2, Ud2 in TxPDO 2 the maximum values
for the calibration are set, like they are output in the calibration menu. The average
from Udl and Udr is calculated.
The calibration should be proceeded at 10 kHz wire frequency as the frequency
compensation is also referred to this frequency.

*) By writing the signature “cali“ in ASCII code (hex-Code: 0x696C6163) or “ilac“ (hex-Code:
0x63616C69) on sub index 1 respectively 2 the corresponding calibrations are started and stopped by
reading sub index 1 respectively 2. After that the parameters should be saved. Furthermore a reset is
recommended.
