With this object the gain of the A/D-converter channels can be corrected. The gain value, with
which the measured A/D-converter value is multiplied, is calculated as:
Calibration_Gain_x
Gain_x = 1+ ---------------------------
2
18
with x= 1, 2, 3, 4
The resulting value range for the gain factor is: 0.875 ... 1.125
The default values Gain

_x (x = 1 ...4) are determined during the factory calibration of the
CAN-CBX-AI420. Via object 1011

(restore_manufacurer_parameter) these module-specific
default values can be restored.
