The accuracy of the Flow's power display depends on factors such as the pressure of the cylinder 

against the tyre, the tyre pressure, fluctuating magnetic forces and the difference in mains voltage. 

To guarantee a good power measurement, the brake must be calibrated. For optimal calibration 

we recommend cycling at least 3 minutes beforehand to warm-up the brake. Make sure the tyre 

pressureisbetween7and8bar.

Brake calibration 

The calibration value 0 appears at the bottom. You start the brake calibration with the 

Up arrow

,

(or19mi/h)untilthewordSTOPappears.Themomentyoustop,theFlowcomputermeasuresthe

deceleration of the rear wheel and the new calibration value appears on the display. 

If the calibration fails (e.g. because you began pedalling during the measurement), ERROR appears on the display. 

You can start the calibration again with the 

Up arrow

. You can set the calibration value to 0 with the 

Down arrow.

Use MODE to confirm the settings and switch to the training display.

Settings before you begin 

The Flow registers four training parameters: speed, power, cadence and heart rate.

Two training parameters are shown at any time, on the 2nd and 3rd lines of the display. With the 

Up arrow

 you can switch the 2nd line from speed to cadence, power and heart rate. With the 

Down arrow

 you can switch the training parameters on the 3rd line.

MODE functions for SPEED (km/h or mi/h)  

The 

MODE

 functions on the 1st line of the display correspond to the training parameter on the 2nd 

line. When the 2nd line is set to speed, the 

MODE

 key switches between ETM (elapsed time), TRP 

(trip time), ODO (odometer), MAX (maximum speed) and AVS (average speed). 

The values only reflect the actual time spend cycling since the computer was reset or switched on. If you take a 

break, the data will be retained. Once you resume cycling, the computer begins calculating again, using all the data.

MODE functions for CADENCE (Cad)

When the 2nd line is set to cadence (Cad), TRP means the total number of pedal revolutions during 

thetrip,MAXmeansthemaximumpedallingfrequencyandAVStheaveragepedallingfrequency.
