4.2.2.1 Linear Conversion Method
Selecting this radio button will cause the GK-405 VWRA to apply a linear conversion
factor to convert subsequent readings from Digits to Engineering Units. This also enables
the Linear Coefficients parameters (Figure 74). A detailed description of each of the
available parameters appears below.
Figure 74 - Linear Coefficients
Output Calculation:
This parameter
must
be set for each sensor before sensor settings
can be saved. This parameter ensures that the "gage factor" (below) will be correctly
signed if entered directly as printed on the calibration sheet.
Valid selections are: "G(R0 - R1)", "G(R1 - R0)" and "Digits Only". When this parameter
is set to "Digits Only" (as shown in Figure 74), no gage factor needs to be entered. The
GK-405 VWRA will display "raw" digits readings. (See Section 3.2 for information on
raw readings). Please consult the calibration sheet for each sensor to determine which
formula,
G(R0 - R1) or G(R1 - R0)
, to select for the setting above.
Zero Reading:
This parameter may be set manually from a previously taken reading.
Please consult your sensor manual regarding various techniques for taking a zero reading.
Gage factor:
This parameter may be entered directly from the Transducer Calibration
Sheet, Linear Gage Factor value.
Offset:
This parameter can be set to any value representing some initial condition. This
value will be added to all subsequent readings.
