7.3. Noise
The "Noise " function can be used to detect noise on the spot, as shown below:
1. The noise waveform is normal, indicating that there is no interference signal or
the interference signal is small in the environment;
2. When the noise waveform has a large square shape or a parabolic shape, it
indicates that the environment has interference signals and the interference source needs
to be eliminated.
