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 s
pecific instructions to set the lockout.

Loop 1/2 
Until you see: 
Upper Display = one of the following: 
NONE – all parameters are read/write 
CALIB – all parameters are read/write except Calibration 
+CONF – configuration parameters are Read Only; no 
writes permitted 
+VIEW – Tuning and Setpoint Ramp parameters are 
read/write. No other parameters can be viewed. 
ALL – Tuning and Setpoint Ramp parameters are available 
for read only. No other parameters can be viewed.
