The Series PD Calibration web page provides access to calibrate any analog inputs or outputs installed. It also
allows restoring factory calibration values, restoring control configuration defaults, and saving or restoring user
settings. These are not typical operator functions and access to this page can be limited by going to Device Con-
figuration > Network > Security. The Administration Security Level is the only level with access to the Calibra-
tion page.
Note: You must enter the Administration Security Level user name and password to access the Calibration web page.

Restoring Factory Calibration
If the Factory Calibration gets corrupted, the Restore Factory Calibration function restores all of the original
factory calibration values for all analog inputs and outputs. To perform a calibration restore, go to Device Config-
uration > Calibration and click on the Restore Factory Calibration button.
Restoring Control Defaults
To set all controller parameter values back to factory default settings, go to Device Configuration > Calibra-
tion and click on the Restore Control Defaults button.
Note: Allow six seconds for all of the parameter settings to get set back to factory defaults values.
Save and Restore User Settings
Recording all the Series PD parameter settings for future reference is very important. If the settings get uninten-
tionally changed, you will need to program the correct settings back into the controller to return the equipment to
operational condition.
After you program the controller and verify proper operation, save the settings into a special section of memory.
To save all user settings, go to Device Configuration > Calibration and click on the Save User Settings button.
If the settings in the controller get changed and you want to restore the last saved user settings, go to Device
Configuration > Calibration and click on the Restore User Settings button.
Note: Only perform the Save User Settings procedure when you are sure that all the correct settings are programmed into the controller.
Saving the settings overwrites any previously saved collection of settings. Be sure to document all controller settings.
