BFM 55 Analog output Gain data (READ/WRITE)
Output Gain data: Analog output voltage or current if digital input in BFM 14 is 16000 (or 1000
as stated in table below) default gain value for voltage mode (-10V/+10V) is 5V (=K5000), for
current mode (4 - 20mA) is 12mA(=K12000) and for current mode (0 - 20mA) is 10mA
(=K10000).
The value of BFM 55 is stored non-volatile in the internal EEPROM. There is a safety function
to protect the internal EEPROM from being destroyed by accidentally writing the same value
continuously to BFM 55.

Note: This table is not applicable for modes 9 to A (see Scaling function settings).
* In absolute voltage output mode, the theoretical value is 16000, however in reality it is not
possible to exceed 10V output voltage (BFM14=10000).
