If the difference is greater than Allowable Change In Dry Fork Frequency, the re-calibration
is rejected. Check the fork for damage, corrosion, or coating, and clean it if necessary
before re-trying.
When the calibration is successful, Dry Fork Frequency is set to the new dry frequency.

Restoring factory calibration of dry fork sensor
This command restores the factory calibration of the fork sensor in dry process conditions.
It is accessible after a site calibration has been performed, but should only be performed
by authorized persons.

6.4.5 Adjust sensor compensation
The frequency of the vibrating fork sensor may be affected by a process temperature
being different to the calibrated temperature. Entering a known process temperature can
compensate accordingly and provide an improved frequency switching point.
Procedure
1. Select Service Tools → Maintenance → Calibrate.
2. Under Sensor Compensation, enter the known Process Temperature.
