Operation Manual
To calibrate a certain distance with a step-by-step guidance, select
1. MENU > Settings > Sport profiles > Running > Stride sensor calibration > By running. Set distance is
displayed.
2. Adjust the distance, how far you wish to run, to calibrate the stride sensor (minimum calibration distance
is 400 meters / 0.3 miles). Press OK. Stand still until stride sensor is found is displayed.
3. Press OK and run xx.x km/mi is displayed. On the starting line, press OK and start your run by taking
the first step with your sensor foot and run the preset distance at a steady pace.
4. Press OK after xx.x km/mi is displayed. Stop exactly on the finish line of the preset distance and press
OK.
5. When the calibration succeeds, Calibrated to x.xxx is displayed. The new calibration factor is used.
Continue recording? is displayed. If you wish to continue the training session recording, select Yes.
Otherwise, select No.
6. To cancel the calibration press BACK, Calibration canceled is displayed.
If the calibration fails Calibration failed is displayed and if you cancel the calibration by pressing BACK,
Calibration canceled will be displayed. If calibration fails, try again.
Set Calibration Factor Manually
The calibration factor is calculated as a ratio of the actual distance to the uncalibrated distance. Example:
you run 1200m, and the training computer shows a distance of 1180m, the calibration factor is 1.000.
Calculate the new calibration factor as follows: 1.000*1200/1180 = 1.017. The measuring range for the
factor is 0.500-1.500.
To calibrate the stride sensor manually before training, select
1. Settings > Sport profiles > Running> Stride sensor > Set factor.
2. Adjust the factor. Calibareted to x.xx is displayed.
The calibration factor can also be set during training, when the stride sensor is in use. Press and hold
LIGHT to enter the Quick menu and then select Calibrate stride sensor > Set factor . Calibareted to x.xx
is displayed and you can continue running.
Calibrate Sensor by Running a Known Distance (on-the-fly calibration)
Before calibration the stride sensor needs to be paired with the training computer. For more information on pairing
the stride sensor and training computer, see Using a New Accessory (page 38).
Set correct lap distance
You can calibrate the sensor at any phase of your training with lap distance correction, provided you are
not training with distance-based targets. Just run a known distance, preferably more than 1000 meters /
0,62 miles.
Make sure the stride sensor function in the training computer is on. In time mode press UP to enter MENU
and select Settings > Sport profiles > Running> Stride sensor > On.
1. In time mode press OK and select Running as your sport profile. Press OK again and start running.
2. At the starting point of a known lap distance, press OK. When you have run the whole lap distance, press
OK.
3. Then calibrate the sensor: Press and hold LIGHT to go enter Quick menu. Select Calibrate stride
sensor.
4. Select Set correct lap distance. Fix the displayed lap distance with the distance you just ran, and press
OK. Calibrated to x.xxx is displayed. The sensor is now calibrated and ready for action.
Set correct distance
Alternatively, you can calibrate the stride sensor by fixing the whole distance gathered.
