Set Correct Lap Distance; Set Factor; Automatic Calibration - Polar Electro M400 User Manual

SET CORRECT LAP DISTANCE

1. Press START in time view to enter pre-training mode, and scroll to the Running profile.
2. Start a session, and run a distance you know that is more than 400 meters.
3. When you have the ran the distance, press START to take a lap.
4. Press and hold light to enter the Quick menu, and choose
Set correct lap distance
5. Set the actual distance you have ran. The calibration factor is updated.

SET FACTOR

To calibrate the stride sensor manually by setting the factor, choose
Stride sensor > Calibration > Manual > Set
ate distance. Calibrated. Factor: xxxx
Manual calibration can also be started during a session, when the stride sensor is in use. Press and hold
LIGHT to enter the Quick menu

AUTOMATIC CALIBRATION

Automatic stride sensor calibration is done based on GPS data and it happens in the background. Current
pace, stride length and cumulative distance will be updated and shown correctly after the automatic cal-
ibration. Your speed is shown in gray on the display until the calibration is complete. If you manually calibrate
your stride sensor later, the GPS based calibration factor will be overwritten.
The automatic calibration is performed twice, and the average of the two calibration factors is used. In your
next training session, the average of your previous calibration factor and the factor obtained during that ses-
sion is used.
The automatic calibration starts after 100 meters. Following criteria has to be met during the calibration dis-
tance of 500 m.
At least 6 satellites have to be available
l
Speed has to be at least 7 km/h
l
Ascent and descent are less than 30 meters
l
When running on different surfaces (e.g. road, trail), use a different sport profile for each of them to achieve the
best calibration for each surface.
To calibrate the stride sensor automatically, choose
