3.6.3 Channel Bias

The module provides a signed 16-bit integer for user to enter a channel bias value
in the configuration table. It can be used to adjust the channel input reading if the
inserted Input Type sensor has measurement offset. The available range is from -
32768 to +32767. The scaling formula with the channel bias applied is:
�� = ���� + �� + ��ℎ���������� ��������
Where:
�� is the final scaled reading shown in the input table.
