NVS-150, NVS-100 (Noise & Vibration Sensor) Function Information

The NVS diagnostic functions currently available in KDS 2.0 and the associated KDS 2.0 diagnostic applications do not support pass/fail determination based on noise level (dB) data.

Although the NVS-150 has a built-in microphone (MIC) capable of collecting noise data, the Pass (OK) / Fail (NG) determination in supported diagnostic applications is based on the analysis of vibration data measured by the accelerometer sensor (G), not on noise data collected by the microphone.

Key points:

• The MIC ON/OFF status does not affect the diagnostic pass/fail results.
• Noise level (dB) values and recorded audio data are not used as determination criteria.
• The Diagnostic result (OK/NG) is determined solely by analysing the acceleration and vibration data collected by the vibration sensor.
• The MIC data measurement and analysis function is not supported by the current diagnostic applications.

Therefore, NVS-based diagnostic functions should be understood as vibration analysis functions rather than noise-based diagnostic functions.
