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
