It was our goal to evaluate whether attachment methods of accelerometers affect activity counts ...The Visual Accelerometer features three fixed ranges, an auto-scale and a peak-hold option. The peak-hold mode stores the maximum acceleration experienced by the sensor after a countdown appears on the LEDs. The zero button on the sensor negates the effect of changing the orientation of the sensor.
