To maintain maximum accuracy, we recommend calibration of the sensor once a year.
The manufacturer recommends calibrating the sensor once a year to maintain maximum accuracy.
Adjustment of the range potentiometer must be done at a temperature between 20°C and 2K.
A maximum slant of 30 degrees is allowed, as larger angles can result in false measurements.
