BFM #41 to BFM #48: Offset data 
BFM #51 to BFM #58: Gain data
Offset data : Analog input value when the digital value is "0"
Gain data : Analog input value when the digital value is as shown below
(The digital value varies depending on the setting of the input mode.)
Standard digital value of offset and gain in each input mode
(A number in the input mode column indicates a value set in BFM #0, BFM #1.)
You can set the offset data and the gain data for each channel.
Write the set value in the unit of "mV" for voltage input or "
µ
A" for current input.
You cannot change the input characteristics in the analog value direct display mode and the
thermocouple input mode. (Even if you write a numeric value, it is ignored.)
