Calibration of sensors

The calibration function integrated into Thermotrack-Webserve allows you to adjust your sensor values based on the discrepancies observed in a calibration certificate.

Thermotrack-Webserve will automatically correct the values using three possible methods:

• Calibration with quadratic correction
  • If you performed a three-point calibration, you can choose a quadratic or second-degree polynomial correction (ax² + bx + c = 0).
• Calibration with linear correction
  • If you performed a two-point or more (up to 5) calibration, you can choose a linear correction (first-degree polynomial or ax + b = 0).
• Calibration by Offset correction
  • If the calibration certificate was done at a single point, all the sensor values will be corrected by the difference observed between the reference and the sensor.

Entering calibration values

There are two methods to enter values into Thermotrack-Webserve:

Automatic method:

You can directly upload a calibration certificate in PDF format. Thermotrack-Webserve will automatically read the information from the certificate, filling in the calibration data, as well as the correction and uncertainty values. Additionally, the PDF certificate can be archived online for easy access and traceability.

Manual method:

You can also manually input the values by following the steps described in this section. This allows you to enter data according to your specific needs.

Simply enter the values of the reference and the sensor. You do not need to enter the correction (the difference between the two values), as Thermotrack-Webserve will calculate it automatically for you.

Important Note:

The calibration uncertainty is not the difference between the reference and the sensor. It is not used for correction but rather serves as an indicator of the quality of the calibration.

Calibration date and validity date

Enter a validity date for the calibration.

Thirty days before the expiration date, you will receive an alarm notifying you to renew the calibration certificate.

Automatic import from CalibExpert

If you performed your calibrations with CalibExpert, the data will automatically be imported into Thermotrack Webserve.
