Chapter 14: Inputs- Using
Creating your own non-linear sensor calibrations (cont.)
The Right Hand output data is automatically updated when the Left Hand sensor data is entered. It is this output data
that will become the actual calibration data when saved.
7. Save your ‘Definition File’ (your entered data) now for later reference or modification (‘Disc’ icon).
8. Press the ‘Curve Fit’ button and adjust to best suit the data using ▲▼. A smooth line
best follows the natural sensor characteristic.
9. Save the actual ‘Calibration File’ that has been generated (as seen in Right Hand columns). Name it
meaningfully (e.g. “Custom Temp deg C”) as this file name is used as the calibration description, as
you will see in the next steps.
Note: Save the files in the default folder location called ‘Custom Cal’ so software knows where to look!
10. Return to ‘Sensor Configuration’ Window and Click on the “+” Icon to add a new sensor
11. In the ‘File’ column you can Click to reveal a button that opens a windows screen, this allows you to
locate and select your ‘Calibration File’. The name you gave the file will be automatically used as the sensor
name and the word “File” added so it can be seen that it is a full calibration table and not just linear (2 points).
That’s it! Your new ‘non-linear’ sensor will appear in the ‘Sensor Name’ list. You can allocate it to a channel now.
