(X: Digital value; Y: Analog signal)
3. Scale range
The analog output mode of a channel has a corresponding digital range. Digital values
correspond to analog outputs sent by a module. For example, if the analog range is -10 V~10 V
and the digital range is -10.0~10.0, the digital values -10.0~10.0 correspond to the analog values
-10 V~10 V.
