The application will collect measures/positions at an average frequency of 1Hz.
Collected positions will be averaged and RMS values will be computed.
The RMS values let the user to verify if the accuracy of the device falls within
some required accuracy upper limit. If the RMS values are not satisfactory then
the user can, and he should, proceed with the calibration.
The user has the control of the number of sample positions used in the RMS
calculation. When the user decides to complete the check, he can press
Stop
to stop the automatic position acquisition.
As said, if the RMS values are not satisfactory then the user can, and he should,
proceed with the sensor calibration.
This operation is also suggested when the user changes the pole height and/or
the pole type (there could be a change in the straightness of the pole).
