Scale Dec parameter configures the decimals presented on the display.
The value of Output High must always be higher than Output Low. Scale
Low and Scale High parameters may have any relationship between them, provided
that they are different. Thus, direct or reverse relationships may be established.
In case of current output, as well as for the input, a linear or squared (FLOW)
relationship may be established, as shown below.
