If the measured values deviate from the real distances, the sensor can be calibrated. To do this, select Calibration under System. Measurement points for calibration are then entered into a table. At least one calibration point is required. However, it is recommended to use at least two widely spaced points. E.g., one point at minimum and one at maximum fill level.

The table builds up from bottom to top. This means that the smallest values are always in the bottom row and the largest values are always in the top row. The table can contain any number of rows. In each row, you assign the real distance to a value measured by the sensor. Once all points have been entered, please save the table. Calibration is then complete.
