Output Calibration

6.4 Restore Output Factory Calibration Procedure

Introduction
The factory calibration constants for the Current and Auxiliary Outputs are stored in its
non-volatile memory. Thus, you can quickly restore the "Factory Calibration" for those
outputs by simply changing the CO RANGE or AO RANGE to the other setting and then
changing it back to the original type.
Refer to Table 6-5 Restore Factory Calibration for procedure
ATTENTION
A restored factory calibration overwrites any previous field calibration done for the output.
Protect your field calibration from accidental overwrites by configuring the appropriate
LOCKOUT selection after calibration.
See Section 3 - Configuration for specific instructions to set the lockout.
