6.6 Restore Factory Output Calibration
Introduction
The factory calibration constants for the Current 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 setting for that output to the other setting and then
changing it back to the original type.
Refer to Table 6-8 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.
