To set a single point calibration:

* select “Single temperature point adjustment”,
* enter reference temperature value in “Hot-reference temperature \[°C]” field,
* enter calibration adjustment value in “Hot-reference adjustment \[°C]”
* optionally add a comment,
* click “Set” button to save the calibration settings in the sensor.

To set two points calibration:

* select “Two temperature points adjustment”,
* enter reference temperature values in “Cold/Hot-reference temperature \[°C]” fields (check that value in “Cold-reference temperature” field is lower than in “Hot-reference temperature” field),
* enter corresponding adjustments in the “Cold/Hot-reference adjustment \[°C]”
* optionally add a comment.
* click “Set” button to save the calibration settings in the sensor.

FU003 and FU004 sensors offer a functionality to restore the default calibration values set during production.
