FAQ#110 – What’s the purpose of the linear and polynomial factors written in the Calibration Reports?

Utilize the Linear Sensitivity Factors (A, B) and Ploynomial Sensitivity Factors (A, B, C, D) of the Calibration Reports permit to obtain readings in engineerig units with a maximum error as for the Calibration Report.

In the case of analogue gauges, the factors shall be applied on the electrical readings (i.e. mA, mV, digit, etc…)

In the case of digital gauges in “Legacy mode” (digital gauges with FW version 0.X, 1.X, 2.X or 3.X), the factors shall be applied on the output in engineering units (i.e. sin angle, kPa, etc…)

In the case of digital gauges in “Normal Mode” (digital gauges with FW version 3 or higher), the factors are already applied inside the gauge, so the Sensitivity Factors shall not be utilized with these instruments.
NOTE: all the new digital gauges are in “Normal mode”.
