How to know if your pedometer is accurate

How to know if your pedometer is accurate

Perform one or both of these tests to determine if your pedometer is accurate:

Step test

1. Set your pedometer to zero.
2. Attach the pedometer to your waistband near the front of your hipbone and
in line with the middle of your knee (on either side of your body)
3. Walk 100 steps and count each step as you take it.
4. Compare the number of steps to what your pedometer records.

Shake Test

1. Set your pedometer to zero.
2. Hold your pedometer in an upright position as if it were clipped to your waistband.
Your pedometer will not be accurate if it is tilted out of an upright position.
3. Shake your pedometer 100 times.
4. Compare the number of shakes with what your pedometer records.

An accurate pedometer has no more than a 10% error. For example, your pedometer will count no less than 90 steps and no more than 110 steps for each of the tests.

The best pedometers have no more than a 5% error. For example, your pedometer will record no less than 95 steps and no more than 105 steps any of these tests.
