4.2.2.2 Polynomial Conversion Method

Selecting this radio button will cause the GK-405 VWRA to apply polynomial

conversion factors to convert subsequent readings from Digits to Engineering Units This

also enables the Polynomial Coefficients parameters (Figure 75). A detailed description

of each of the available parameters appears below.

Coefficient A: Enter the Polynomial Gage Factor A from the Sensor Calibration Sheet

for this parameter.

Coefficient B: Enter the Polynomial Gage Factor B from the Sensor Calibration Sheet

for this parameter.

Coefficient C: This parameter should be calculated from a field zero reading. Please

refer to your transducer manual for further details on how to calculate Coefficient C.

4.2.3 Sensor Settings Page Three, Units Conversion

The third page of the Sensor Setting window (see Figure 76 on the following page)

contains parameters that allow a conversion factor to be applied to data (in Engineering

Units), converting it into a user selected unit of measure. A detailed explanation of the

parameters for the Unit Conversion window appears below.
