P|Prox displacement sensor: Device configuration

Application configuration / calibration

Factory default calibration for the P|Prox family is completed using an aluminum target of a specified size, which varies with different housing sizes. In-application calibration (1-point and 3-point calibration) can improve performance.

1-point calibration

This calibration is best suited for large targets and all metals other than aluminum. The characteristic curve is linearized over the entire range based on a single distance point.

Instructions:

1. Place the flat surface of the target directly against the sensing face of the sensor.
2. Open moneo|configure and scroll to the "Application" section.
3. Select "1-point calibration" and click on "Execute command"
4. After approximately 5 seconds, you will see a pop up window stating that parameters were successfully written to the device, indicating the 1-point calibration is complete..

3-point calibration

This calibration is best suited for small, non-uniform targets, such as screw heads, and all metals. The characteristic curve is linearized over the entire range based on three distance points.

Instructions:

1. Click on "3-point calibration". Parameters [SMR], [CMR], and [EMR] will appear.
2. Click on "Execure command" next to [SMR] and a popup window will be displayed.
3. Scroll to the correct distance, place the metal target at that distance, and click "OK".
4. Repeat for [CMR] and [EMR].
5. Click on "Execute 3 Point calibration". 
6. After approximately 2 seconds, you will see a pop up window stating that parameters were successfully written to the device, indicating the 3-point calibration is complete..
