声音为目标点

In order to guide the user of manual inspection device to the target point, ARCO, in addition to the Guided coordinate points, enhance now proximity sound information.

The frequency of the sound is related to the distance, a lower frequency means an higher distance: once the user arrives in the target sphere (which is set in the control Panel of ARCO) the system stop the sound and the user knows that he met the point to be measured.
