scale factor

Multiplier used to convert analog and serial inputs into engineering units. Bias and scale are used in the following formula to convert transducer output voltage to engineering units:

Value = (Voltage * Scale) + Bias

To compute the scale factor, use the following formula:

Scale = (High Value - Low Value) / (High Voltage - Low Voltage)
where voltage must be in the range of 0 to 10.

This field requires an input value significant to 3 decimal places. Values can be positive or negative. For Netstal source types, the scale factor for the desired Parameter Number and Convert Index must be obtained from Netstal's PLC Interface Table. For simulated sources, the scale factor is applied to the simulated signal. For Engels, the scale factor is applied to the received value.
