3.5.2.1. Window Size
The A_OUT > TchMid > WndSize option sets the window size that the Midpoint TEACH uses to set the 4 mA (0 V) and 20 mA (10 V) setpoints.
The taught surface must be inside the defined sensing range, and at least one setpoint (with offset applied, if any) must be located within the
sensing range.
The Analog Output window size is a different setting than the Discrete Output window size when defined using the push buttons.
