C3.8 Fixed Biasing
The fixed biasing function adds a constant bias to input values throughout the input
range.
This function is especially useful when a sensor output is always lower than true values
by a fixed amount due to the physical condition of the sensor. For example, it may be
used when the temperature of a material in a furnace is indirectly determined by
measuring the ambient temperature in the furnace, where a fixed bias is added to the
ambient temperature to represent the temperature of the material. The function is also
useful for rectifying deviations among outputs from different sensors, which are within
precision tolerance, or for correcting the output from a degraded sensor.
