To calibrate the diameter on a PONSSE H73:

1. Ensure the tree travels in the center of the harvester head. If needed, adjust it using the reaction brace.
2. Check that measurements A and B are equal. If the difference is greater than 5 mm, adjust the reaction brace. A half revolution changes the difference by 5 mm. Recheck the measurements.
3. When the feeding rollers are closed, the sensor reading must be 30. If not, adjust it by turning the sensor body.
