8.4.4.2 Set the linearization table (60 breakpoints)
Procedure
1. Select the "Custom type" option for the "Type" parameter.
2. Select a custom type from the list, e.g. resistance.
3. Select the "Linearization table" option for the "Linearization type" parameter.
4. Enter the desired number of breakpoints.
You can enter a minimum of 3 and up to 60 breakpoints.
5. Enter the x values and associated y values.
6. Transfer the linearization table to the device.
7. Test the expected functionality for your application.
There is no internal validation check in the Engineering System.
8.4.4.3 Set the spline curve (40 breakpoints)
Procedure
1. Select the "Custom type" option for the "Type" parameter.
2. Select a custom type from the list, e.g. resistance.
3. Select the "Spline curve" option for the "Linearization type" parameter.
4. Enter the minimum and maximum X value.
5. Enter the desired number of breakpoints.
You can enter a minimum of three and up to 40 breakpoints.
6. Enter the values of the Y points.
7. Transfer the spline curve to the device.
8. Test the expected functionality for your application.
There is no internal validation check in the Engineering System.
8.4.5 Sensor calibration
8.4.5.1 Introduction
The sensor calibration can be a one-point calibration and a two-point calibration.
You use the one-point calibration to set the device characteristic at the low calibration point.
You use the two-point calibration to set the device characteristic at the low and high calibration
point.
The results are correct measured values at the calibration points.
