Built-in self-vibration monitoring providing information about vibrations that influenced the measurement results.

Time history logging.

Audio recording option allow sound to be recorded for playback and identification purposes.

Insert the microphone into a calibrator, and it automatically activates the calibration process.

Data is stored on a SD card inside the SVAN 971.

Download data to PC using the free Svantek software. Creates measurement reports quickly.
