6 CALIBRATION & CORRECTION FACTOR
6.1 WHy CALIBRATE?
Everyone has a different walking and running style, which affects the
measurement. Therefore, you should set up (calibrate) the R3
transmitter for your running and walking style. If you use the factory
presets, the running computer may or may not provide you with
accurate data. Calibrating the sensor makes the measuring much more
precise.
6.2 CALIBRATION FUNCTION
The running computer has a calibration function. For the calibration, wear
the R3 transmitter and the running computer and run a distance that
is known to you. You can measure a distance in advance with a bike
computer, or run on a 400-meter track. After you have run the distance,
adjust the measured value to the actual distance run.
As your running or walking styles change as you change speed, the
calibration is carried out in the slow and fast speed respectively.
For the sensor positions chest and hips, you can perform two
calibrations:
Walking
k
Running
k
Important: To properly calibrate your computer, you must perform the
test twice at a minimum distance of 800 m.
