Calibration By Running Wizard; Set Calibration Factor Manually; Calibrate Sensor By Running A Known Distance (On-The-Fly Calibration) - Polar Electro RCX5 User Manual

If you select Running as your sport profile and do walking activities, there is no need to calibrate the s3+ stride
sensor.

Calibration by Running Wizard

Before you can calibrate the stride sensor it 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 41).
Make sure the stride sensor function in the training computer is on. Select
Running > Stride sensor >
To calibrate a certain distance with a step-by-step guidance, select
1. >
Settings Sport profiles
2. Adjust the distance, how far you wish to run, to calibrate the stride sensor and press the OK to confirm.
Stand still until stride sensor is found
3.
Press OK and run ... km/mi
4. Press the OK and start the run by making the first step with the sensor foot onto the starting line and run
the preset distance at a steady pace.
5.
Press OK after xxx km/mi
6. Stop exactly on the finish line of the preset distance. Press OK.

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

2. Adjust the factor.
The calibration factor can also be set during training, when the stride sensor is in use. Press and hold

*Optional s3+ stride sensor required.

Calibrate Sensor by Running a Known Distance (on-the-fly calibration)

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.
Make sure the stride sensor function in the training computer is on. In Time mode press UP and select

Settings Sport profiles
1. In time mode press OK once. Browse the sport profiles with UP/DOWN and select
OK. Start running.
2. When you are at a 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 to
4. Fix the displayed lap distance with the distance you just ran, and press OK.
