INTRODUCTION 

 

The following procedure will allow you to effectively calibrate your MET 250/220 system to insure 
accuracy and maintain peak performance. 

Perform the following procedure step by step, in sequence, to: 
 

1.  Alter Tip Temperature values. 
2. Alter 

Tip Temperature Offset values. 

3.  Determine and/or alter feature status and defaults stored in the system. 
4.  Recalibrate the system for accuracy. 

 

PROCEDURE  

KEYLOCK OPTION 

 

KEYLOCK 
1. An optional KeyLock feature is available from PACE which 
prevents unauthorized alteration of stored data or calibration of the 
system. Check the rear panel of the system power source. If the 
KeyLock feature is present there will be a KeyLock switch located in 
the upper left portion of the panel. Use the key to turn the switch to 
the "Unlock" position. If the feature is not present, there will be a 
round plastic filler plug present at that location.

 

NOTE 

 

The KeyLock switch-must be turned  to the "UNLOCK!" position to alter 
any of the data stored in the memory or to recalibrate the system
