1.5 – How to install the cylinder head thermocouple
When using a Cylinder Head Thermocouple (CHT) sensor, always remove the
spark plug washer before inserting the spark plug into the sensor.
When tightening and loosening the spark plug, minimise movement of the sensor

The figure below shows how to correctly install the CHT sensor.
Once the sensor has been correctly installed, plug the thermocouple’s male
Mignon connector to the CHT input wire of the “2 temperatures split cable”.
