Performing Z calibration (device dependent
NOTE
A distortion correction must be performed before the Z-calibration can be performed.
1. Print the required SmartGrid (PDF). Alternatively, ready-made SmartGrids are also provided.
Requirements
- The SmartGrid squares must be a minimum size of 20 x 20 pixels
- At least 6 x 8 squares are required in the Vision Sensor's field of view, preferably more
2. For View, select the angle at which you see the vision sensor. This is for better orientation with
permanently installed vision sensors.
3. Press Start calibration.
4. It is helpful, but not necessary, to place a thin object (such as a nut) in the centre of the vision
sensor's field of view, making it easier to tilt the SmartGrid in all directions. Use the Live View for
placement.
5. Place the SmartGrid onto the placed object, in the complete field of vision of the vision sensor.
6. Now tilt the SmartGrid in all directions.
 The learning progress is displayed as a percentage. If there are enough calibrated positions, the
successful completion of the calibration is displayed.
