# First calibration

Once the sensor has been correctly attached to the calibrator, the first calibration can be started.

![](https://acccal.at/wp-content/uploads/2025/01/Sensor-Calibrate_en.png)

Select the axis to be calibrated from the Axis list and click the ***`Calibrate`*** button [1]. Another dialog opens showing the ***`axis`*** [2], general sensor data [3], which ***`calibrator`*** [4] and which ***`calibration point template`*** [5] will be used. It is best to use the existing "Fancy"***`report template`*** [6]. This is followed by two user-defined fields [7] that require an entry. Press ***`Start`*** and the calibration will begin.

In the upper area [1] you can see which action the calibrator is currently performing, below this the determined sensitivity [2] and then the deviations from the determined sensitivity over the various frequencies [3]. A successful calibration is shown in the lower area [4] with a green bar, an unsuccessful calibration with a red bar. Pressing the ***`Save`*** button saves the calibration in the database and generates the certificate.

**Congratulations, you have calibrated your first sensor.**
