Measurement of performance data on an indoor trainer is important. All the Tacx Smart trainers are measuring Speed, Cadence and Power. In order to have an accurate power measurement the trainer needs to be calibrated. This is done by a simple and quick spin down calibration process.
The spin down calibration process can be triggered from the Tacx Utility app. The application will guide you through all the steps. You only need to calibrate the trainer once when this comes out of the box.
What to do?
- Download and install the Tacx Utility app
- Select calibrate
- Then cycle to the desired speedlevel mention on screen.
- The FLUX does not need to be adapted afterwards.
Note: the calibration value of the trainer is stored within the trainer electronics, meaning that, unless the calibration value is overwritten by a follow-up calibration, this value is being used during every training
Why is calibration required?
There are many factors (e.g. room temperature, tire pressure, rolling resistance, etc.) influencing the power measurement. With a calibration all these factors are measured and calculated to a single calibration value. The value is being used as a coefficient to calculate the power input of the cyclist.
The FLUX has an accuracy of 3%.
