Out of the box, the Sport Kit is only 90 percent accurate. You can expect (according to Nike and Apple) your sensor to be 98 percent accurate once calibrated, so it is definitely worth the minor extra effort it takes to calibrate. Here’s how:
- Measure out a route to use for calibration.
- Find a route that is a minimum of 400 meters in distance. If you have access to a high school or other public track, this is a great place to calibrate since the track is exactly 400 meters around (on the inside lane). If you have no access to a track, you can map out a route at gmap pedometer.
The following 8 steps have accompanying screen shots at the bottom of this article.
- On your iPod menu select “Nike+iPod.”
- Then select “Settings” on the workout menu.
- Next select “Calibrate” from the sensor menu.
- On the next calibration screen push the center button to continue.
- Select either “Walk” or “Run” depending on what you want to calibrate.
- If you have previously calibrated either your run or walk, your iPod will show the date of your last calibration.
- Choose either a “Custom” distance or the default “400 meters.”
- If you chose the custom distance select your mileage using the iPod dial.
You will be told to begin your workout and you will receive spoken feedback when your calibration distance is completed. Repeat this process if you also want to calibrate your walking or running pace.
Calibration does not need to be repeated unless there is a significant change in your running speed. For a list of frequently asked technical question relating to your Sport Kit, please visit Apple’s Web site.
