5.6  Restore Input Factory Calibration 
Introduction 
The factory calibration constants for all the input actuation types that can be used with 
the controller are stored in its non-volatile memory. Thus, you can quickly restore the 
“Factory Calibration” for a given input actuation type by simply changing the actuation 
type to another type and then changing it back to the original type.  
Refer to Table 5-13  Restore Factory Calibration for procedure 
ATTENTION 
A restored factory calibration overwrites any previous field calibration done for the input and 
may change the High and Low Range Limits.  
Protect your field calibration from accidental overwrites by configuring the appropriate 
LOCKOUT selection after calibration.  
See Section 
3 – Configuration for s
pecific instructions to set the lockout.
