Input Calibration
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 the Section 3 - Configuration for specific instructions to set the lockout.
