4.2.1.1 ADC raw value and initialisation value
ADC raw value and initialisation value 4- ][Funktionsbeschreibung_BA_Konfig Skalier ADC
You can configure each channel so that the raw value from the AD con-
verter is issued directly, without calibration or scaling.
If the AD converter fails to supply a valid value, the module will adopt the
ADC initialisation value for this channel instead. The default value is
4096
D
(1000
H
).
4.2.1.2 Hardware calibration
Hardware calibration 4- ][Funktionsbeschreibung_BA_Konfig Skalier HW-Abgleich
Each channel is calibrated ex-works in order to correct component dis-
persion and other influences.
The range is divided so that zero is assigned the value 0 and the end
point is assigned the value 4095
D
(0FFF
H
).
4.2.1.3 Manufacturer scaling
Manufacturer scaling 4- ][Funktionsbeschreibung_BA_Konfig Skalier Herst. Ein
The manufacturer scaling is used to define the offset (zero point com-
pensation) and gain (amplification) of the digital signal.
Manufacturer scaling active (default setting)
 Default values for manufacturer scaling:
– Offset (b
1
): 0
– Gain (a
1
): 8194
D
(2002
H
)
INFORMATION
The default setting for gain (a
1
) means an amplification factor of
8.
