What is the first step in checking the calibration on a mechanically-braked cycle ergometer?

The first step in checking the calibration on a mechanically-braked cycle ergometer involves removing the belt from the wheel. This action is necessary to ensure that there is no interference from the resistance mechanism while assessing the calibration of the machine. By detaching the belt, you can more accurately evaluate how the ergometer responds to calibration adjustments and ensure that the measurements obtained reflect the true performance and resistance settings of the device.

After this initial step, other calibration procedures would typically follow, such as identifying resistance levels and ensuring that the readings correspond accurately to known weights. This systematic approach is crucial for maintaining the integrity of the exercise testing and ensuring that the results are reliable for any subsequent assessments.
