Enter the numeric channel value in the selected representation.
How the scaling works
Fraction = (program value − program minimum) ÷ (program maximum − program minimum). Engineering and physical values use the same fraction of their configured spans. Reverse scaling starts with the engineering fraction.
Results are ideal linear estimates. The calculator does not read hardware, status bits, calibration, or fault state. Values are never silently clamped; integer targets are shown separately from the ideal result. Descending engineering scales are supported.
