4.3  Exchange of the Sensing Head 
From  factory  side  the sensing head  has already  been 
connected to the electronics and the calibration code has been 
entered. Inside a certain model group any exchange of sensing 
heads  and  electronics  is  possible.  The  sensing  heads  and 
electronics  of  the  CTfast  models  (LT15F  and  LT25F)  and
CT 4M cannot be exchanged. 
4.3.1  Entering of the Calibration Code 
Every head has a specific calibration code, which is printed on the 
head cable.  For  a  correct  temperature  measurement  and 
functionality  of  the  sensor  this calibration  code  must  be  stored 
into the electronic box. The calibration code consists of 3 blocks 
(1M, 2M, 3M = 5 blocks) with 4 characters each. 
For entering the code please press the Up and Down key (keep pressed) and then the Mode key. 
The display shows HCODE and then the 4 signs of the first block. With  Up and Down each sign can be 
changed; Mode switches to the next sign or next block. 
The entering of a new calibration code can also be made via the CompactConnect software (optional). 
After exchanging a head the calibration 
code of the new head must be entered 
into the electronics.
