test24: Read calibration data from CP2103 EEPROM
The calibration box contains a voltage reference that has to
be calibrated for each input voltage range of the FmcAdc.
A multimeter of at least 6 digits has to be used for the
calibration. The result of the calibration is stored in the
cp2103 EEPROM.
