4.5 Exchange of the sensing head
• After exchanging a head the calibration code of the new head must be entered into the
electronics.
• After modification of the code a reset is necessary to activate the changes.
[►5 Operation]
• The calibration code is fixed on a label on the head. Do not remove this label or note the
code. The code is needed if the electronic must be exchanged.
• The sensing head of the CTlaser 4M cannot be exchanged.
The sensing head is already connected to the electronics by factory default. Inside a certain model group an
exchange of sensing heads and electronics is possible.
Entering of the calibration code
Every head has a specific calibration code, which is printed on the head. 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 five blocks with 4 characters each.
Example: EKJ0 – 0OUD – 0A1B – A17U – 93OZ
