The Polar RCX3 training computer provides four sport profiles; one for running, two for cycling and one for other sports.
Adjust the settings for the sport profiles to suit your training needs in MENU > Settings > Sport profiles. You can, for example, activate the sensors you want to use in the sport. Then when you start a training session using the sport profile, the training computer detects the needed sensors automatically
When you activate an optional sensor ( s3+ stride sensor, G5/G3 GPS sensor, CS speed sensor W.I.N.D. or CS cadence sensor W.I.N.D.) for the first time, it needs to be paired with the training computer. For more information on the sport profile settings and pairing a sensor with the training computer, see Sport Profile Settings and 11. Using a New Accessory.
↑ Back to topPolar s3+ stride sensor can be set on only for the Running sport profile.
Calibration of the stride sensor improves the accuracy of speed/pace and distance measurements. It is recommended that you calibrate the stride sensor before using it for the first time, if there are significant changes in your running style, or if the position of the stride sensor on the shoe is dramatically changed (e.g. if you have new shoes or if you switch the sensor from your right shoe to your left one). You can calibrate the stride sensor by running a known accurate distance, or by setting the calibration factor manually. The calibration should be done at the speed you normally run. If you run at different speeds, the calibration should be done at your average speed.
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 11. Using a New Accessory.
Make sure the stride sensor function in the training computer is on. Press to enter MENU and select Settings > Sport profiles > Running> Stride sensor > On.
To calibrate a certain distance with a step-by-step guidance, select
MENU > Settings > Sport profiles > Running > Stride sensor calibration > By running. Set distance is displayed.
Adjust the distance, how far you wish to run, to calibrate the stride sensor (minimum calibration distance is 400 meters / 0.3 miles). Press . Stand still until stride sensor is found is displayed.
Press OK and run xx.x km/mi is displayed. On the starting line, press and start your run by taking the first step with your sensor foot and run the preset distance at a steady pace.
Press OK after xx.x km/mi is displayed. Stop exactly on the finish line of the preset distance and press .
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.
To cancel the calibration press , Calibration canceled is displayed.
If the calibration fails Calibration failed is displayed and if you cancel the calibration by pressing , Calibration canceled will be displayed. If calibration fails, try again.
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
Settings > Sport profiles > Running> Stride sensor > Set factor.
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 to enter the Quick menu and then select Calibrate stride sensor > Set factor . Calibareted to x.xx is displayed and you can continue running.
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 11. Using a New Accessory.
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 to enter MENU and select Settings > Sport profiles > Running> Stride sensor > On.
In time mode press and select Running as your sport profile. Press again and start running.
At the starting point of a known lap distance, press . When you have run the whole lap distance, press .
Then calibrate the sensor: Press and hold to go enter Quick menu. Select Calibrate stride sensor.
Select Set correct lap distance. Fix the displayed lap distance with the distance you just ran, and press . 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.
In time mode press and select Running as your sport profile. Press again and start running.
Press and hold to enter the Quick menu. Select Calibrate stride sensor.
Select Set correct distance. Fix the displayed distance with the distance you just ran, and press . Calibrated to x.xxx is displayed. The sensor is now calibrated and ready for action.
During training, there is also the possibility to set the calibration factor manually. Press and hold to enter Quick menu. Select Calibrate stride sensor > Set factor.
