Calibrate the Foot Pod

Optional calibration of the foot pod improves accuracy of speed, pace, and distance* measurements. It is recommended that you calibrate the foot pod before using it for the first time, if there are significant changes in your running style, or if the position of the foot pod on the shoe is dramatically changed (e.g. if you have new running shoes). You can calibrate the foot pod by running a known distance, or by setting the calibration factor manually.

Calibrate Foot Pod by Running a Distance (on-the-fly calibration)

You can calibrate the foot pod at any phase of your exercise with lap distance correction, provided you are not exercising with distance-based targets. Just run a known distance, preferably more than 1000 meters.

Make sure the foot pod function in the running computer is on:

Select Settings > Features > Footpod

In the time mode press OK twice, then start running.

You can calibrate the foot pod during any lap of the run. When you are in a starting point of a known lap distance, press OK and start running. When you have run the whole lap distance, calibrate by choosing either alternative:

1.Stop running, stand still, and press and hold LIGHT to go to Settings. Or,

2.Stop running, stand still, and press STOP once. Select Settings.

Select Calibrate > Correct lap > Set true lap distance. Fix the displayed lap distance with the distance you just run, and press OK.

Calibration complete and the factor are displayed. The foot pod is now calibrated and ready for action.

Set Calibration Factor Manually

The calibration factor is calculated as a ratio of the actual distance to the uncalibrated distance. Example: you run 1200m, the running computer shows a distance of 1180m, the calibration factor is 1.000. To calculate the new calibration factor as follows: 1.000*1200/1180 = 1.017. The measuring range for the factor is 0.500-1.500.

There are four options for setting the calibration factor:

1.Before exercise.
