5.4.13 BFM #30: Model code

"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:
• Offset data:
