# Calibration

The Calibration function is used to set the Logger card calibration adjustment.

The user must be logged into the system for this function to work.

There are 3 types of cards offered by ICU Scandinavia AB:

1. FU002 - Transport logger card Standard
2. FU003 - Transport logger card High resolution
3. FU004 - Transport logger card High temperature

The cards are calibrated during the production, but a user can change the adjustment if needed.

To calibrate a card:

1. Connect the card to the reader and click the <img src="https://3047013119-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgejpyNLdjbUCpCURIFfT%2Fuploads%2FeeddYXtyK5sjdtuvZuuO%2Fimage.png?alt=media&#x26;token=f0d6e809-1c04-4cb6-9717-028233f91896" alt="" data-size="line"> icon.

The upper form part provides information about the current calibrator, the date of calibration and a comment.

To set an adjustment:

* enter adjustment value in “New adjustment \[°C]” field,
* optionally add a comment,
* click “Set” button to save the calibration settings in the sensor.

The message box will inform about the save procedure result:

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.
