After the first calibration is complete. Take
zero and full scale data at room temperature.
This secondary calibration will improve the
overall accuracy.
The correction factors generated by the
secondary calibration are shown here. The
GainDAC Correction should be about close to
1.0 and the ZeroDAC correction should be close
to zero.

9.5 Customization of the PGA309EVM Calibration Spreadsheet
All of the cells as well as the VBA code in the spreadsheet are open and can be modified and adjusted for
individual design and sensor properties. The name of the custom sensor curve-fitting function is
sensbridge()
.
This function can be modified to fit sensors modeled by more complex equations than shown in Equation1. In
this case the following parts of the spreadsheet must also be updated:
-
curve-fitting coefficient equations in the framed area A17:I52, worksheet Sensor Curvefit;
-
references to the
sensbridge()
in the cell equations in the worksheet Sensor Data vs. Temp, columns
D, F, K, L;
-
references to the
sensbridge()
in the cell equations in the worksheet Sensor Data vs. Pressure,
column B
Note:
The equations generating the Lookup Table in the worksheet Calibration Results can stay.
