ALTA Vibration Meters use an accelerometer to measure g-force and then determine speed and frequency. They can be set to only capture when a vibration occurs and sleep when no vibrations are present, or they can be set to measure at a given assessment interval regardless of ...ALTA Vibration Meters use an accelerometer to measure g-force and then determine speed and frequency. They can be set to only capture when a vibration occurs and sleep when no vibrations are present, or they can be set to measure at a given assessment interval regardless of whether a vibration has occurred.
The Vibration Meter will also report the duty cycle, or how long the sensor was measuring vibrations throughout the heartbeat.
