Not clear how to calibrate the box
Test21 reads:
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.
It is not clear:
- how this calibration should be done
- what's the data format of the calibration data
- which programs to write the calibration data

Here you find also the manual, and it seems that these tests are useful
for the calibration:
19 ADC and offset DAC calibration
23 IPMI and calibration data write to FMC EEPROM
25 Calibration verification
One may have a look at the Python program that is used to only
calibrate:
fmcadc100m14b4cha_calibr.sh
This one only runs tests 00 22 19 23 25.
