This equation is in the form:
The coefficients K
i, j
, X and Y are printed on the calibration certificate supplied with the
pressure sensor. A sample set is shown in Table 2-1:
2.4 Stored Coefficients
The coefficients are also stored internally on a serial EEPROM. See Appendix B. for details on
data format and communication information.
where: P = Applied pressure in mbar
K
i, j
= Calibration coefficient
x = Pressure signal in Hz
X = Pressure normalizing factor
y = Temperature signal in mV
Y = Temperature normalizing factor
