The 0-Watt Start-up System gives the opportunity to start the ergometer without load at a preset pedal speed (rpm). You can choose any pedal speed between 30 and 60 rpm. The number of revolutions is increased from 0 to the required rpm by means of a motor drive. With this option there is no energy-loss due to the start-up phase. The test subject can start the exercise with the target rpm and the lowest load of the ergometer, which is 7 watt. To be able to operate this option the ergometer needs to be executed with a 7" control unit with touch screen.
