4.17 Restore Factory Calibration

Introduction
The factory calibration constants for all the input actuation types that can be
used with the controller are stored in its nonvolatile 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 4-15 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.
Be sure to protect any field calibration from accidental overwrites by configuring
the appropriate LOCKOUT selection after calibration.
See Section 4.15 for specific instructions to set the lockout.
