Front Panel Calibration Procedure 

These procedures assume you understand how to operate front panel keys (see chapter 5). Make sure the 
sense terminals are directly jumpered to the output terminals.

To begin calibration press 

Shift Cal

, scroll to CAL ON and press 

Enter

4. 

Enter the calibration password from Entry keypad and press 

Enter

. lf the 

password is correct the Cal annunciator will come on.  
If CAL DENIED appears, then an internal switch has been set to prevent the 
calibration from being changed. 
lf the password is incorrect, an error occurs. If the active password is lost, the 
calibration function can be recovered by setting an internal switch that defeats 
password protection (contact the factory for details).
