"K2080" (fixed value) is stored as the model code.

5.4.14 BFM#41 to #44: Offset data / BFM#51 to #54: Gain data

If the input mode is specified in BFM#0, the offset data and the gain data of each channel will be automatically
stored. The initial offset data and gain data are set for each mode as shown in the following table:

Analog input value when the digital value is "0" (reference offset value)
Analog input value when the digital value is equal to the reference gain value (The
reference gain value depends on the set input mode.)
