Properties Group  Parameter  Index #  Parameter Description  Value or Selection 
 Scale Factor 
0  K - Multiplier (scaling) constant  –99999 to 99999 
 Bias 
1 
Bias Constant - is used to 
compensate the input for drift of 
an input value due to 
deterioration of a sensor, or 
constant offset to an input.
