Connecting the brake

mi/h until the word Stop appears to start up calibration. When you stop the i-Vortex computer will
measure the deceleration of the rear wheel and the new calibration value will appear on the display.
Arrow right saves the calibration value to memory and continues to next step.
When calibration has failed, for instance because you started cycling during the measurement, the display will
show CAL FAIL. Use Arrow up to start calibration again.
Settings before the start
The accuracy of the i-Vortex power display depends on de pressure of the roll on the tyre, tyre
pressure, variable magnet forces and mains tension variations, amongst other things. In order to
guarantee correct measurement of power you need to calibrate the brake. For optimum calibration
we recommend you ride for 3 minutes at least, to ensure the brake is properly warmed up.
Scale factor
The value for scale factor is blinking. When you start cycling you activate the function to adjust the
scale factor. Next to speed, the power corresponding to the scale factor in question will appear. If you
possess an external power meter you can compare these values. Using Arrow up or Arrow down you
