To judge whether a mechanical vibration sensor pedometer is accurate, it is necessary to keep the pedometer body vertical to the horizontal plane, and swing the pedometer up and down with light force, with a swing distance of about 3~5 cm. At this time, the pedometer needs to be 100% correct to be qualified.
Judge whether a 3D vibration sensing (gravity acceleration sensing) pedometer is accurate, hold the fuselage so that the flattest plane of the fuselage is parallel to the horizontal plane, swing the pedometer up and down with light force, and observe the counting.
There is an error in the pedometer.
1. Walking: the frequency of walking is 100 steps/minute, and the number of steps recorded by pedometer should be within the range of 92~ 108 steps.
2. Running: The frequency of running is 170 steps/minute, and the running is 100 steps. The number of recorded steps should be within the range of 95~ 105 steps.
3. The pedometer does not have any packaging, and it falls freely twice from the height of 80CM on the concrete floor. After two times, the pedometer can still work normally.
