Restoring Factory Settings (1-3-4)
Note
After restoring factory settings you will
need to re-configure and calibrate the
instrument.
From the Online menu, select Configure / Setup, then
select Calibrate, and Restore Factory Settings. Follow
the prompts on the Field Communicator display to
restore calibration and all parameters to the factory
settings. You should only restore the calibration if it is
not possible to calibrate an individual sensor.
Restoring calibration returns the calibration of all of the
sensors and the tuning set to their factory settings.
Following restoration of the factory calibration, the
individual sensors should be recalibrated.
