Maintenance Procedures 

 

4.3 

Boards Interchangeability 

 
Main and input boards are supposed to stay together, because calibration data from input board 
circuit is stored in EEPROM of the main board. 
 

WARNING 

If, for some reason, you separate the input and the main boards, you must do a trim to guarantee precision of 
the inputs.  With mismatched boards, the factory trim will not be as good as it was.
