Explanation: When comparing the measured fill level with the output value of the sensor taking the installation
height into consideration, it was determined that the value was 1 cm too high. As the "Trim" and "Sensor offset"
parameters are added to the scaled measurement value, this error can be balanced out by setting the "Trim"
parameter value to -0.01 m.
