Technical data:
- connection interface for the Pt100: G1/2’’, external thread.
- connection wires of the Pt100: 26 AWG multi-conductor, PTFE jacket
- connector between the Pt100 wires and the electronic board: Molex® 90327-3304

Calibrate the controller
Once the Pt100 has been mounted onto the 8400 controller:
- plunge the Pt100 into a vessel filled with water: read out the temperature indicated by the
display of the controller.
- measure the real temperature of the water inside the vessel using a thermometer and note it
down.
- Enter the Calibration mode of the controller.
- Select the T°-menu, validate and enter the difference between the real temperature and the
temperature measured by the 8400, i.e. 24.4 - 24.2 = 0.2 in the example above.
- Measure again the temperature of the water inside the vessel using the 8400 and check it
displays 24.4 °C
