There are two Nike products capable of calibration with a treadmill, the Nike+ Sportband and the Nike+ Ipod Nano. The Sportband and the Ipod Nano, accompanied by Nike+ shoes, track and record information from your walking or running workout. Calibration is the same for both products. You should complete calibration as soon as possible to ensure that your running and walking record is accurate. Calibrating with a treadmill is a convenient and accurate way to adjust your Nike+ device.
Treadmill
A treadmill is a useful tool for calibrating your Nike+ device. When you calibrate, you need to compare the known distance of your run or walk with the recorded distance. For example, if you know that you ran one mile and the Nike+ records that you ran .8 miles, you can adjust the device to reflect that difference in future runs. Treadmills record and display the distance that you have gone during your workout, allowing for easy calibration and comparison with your Nike+ device.
Technique
To calibrate your Nike+ Sportband or Ipod Nano, press the record button on your device and begin your normal run or walk on a treadmill. Do not mix running and walking because it can provide inconsistent data. You should run or walk at least 400 meters, or a quarter-mile, to establish a baseline for calibration. Stop recording when you finish your workout. Check with the treadmill display to see the true distance of your workout and record the number. Connect your device to your computer. Under the "Settings" menu, find the "Calibration" settings and adjust your device to reflect the true distance of your run or walk.
Benefits
Your Nike+ device relies on accurate recording that comes from calibration. The devices measure distance and time, but they also calculate pace and calories burned. Both pace and calories burned reflect how fast you cover a certain distance. If your device is not calibrated properly, this information is inaccurate. Your device, in cooperation with your computer, also allows you to track your progress over multiple runs. If you calibrate after several runs, it will offset your records and spoil the data.
Troubleshooting
After completing your workout on a treadmill, you may experience error settings during the calibration process. Calibration errors usually arise from one of two problems, pace and distance. If your distance is not long enough, the device cannot complete an accurate calibration. If the treadmill you are using verifies that you ran or walked at least 400 meters, choose a different treadmill and start the calibration process again. If the error arises from inconsistent pace, often resulting from a combination of walking and running, then complete the calibration process again, focusing on pace. Running on a treadmill can feel awkward and affect your pace if you are not used to it. After a few practice runs, you should find that your pace and gait have adjusted to the treadmill for better calibration.
