Find a calibration ride out and back segments
To have a more accurate CdA, the Notio device needs to be calibrated as a power meter would. But it is more tedious because we need to perform a calibration ride which is composed of an out segment and a back segment both with the same length. The Notio iOS app will calculate a calibration factor based on your position and your aero profile. You can do the same in GC Notio with more fine tuning. But how to find the out and back segment? There is a feature (still in beta) for finding those segments.
Golden Cheetah has the functionality to “Find intervals…” for a specific ride.First, you will need to download your calibration ride into Golden Cheetah Notio.
Second, compute the data of your ride.
In the sidebar where all the rides are listed, right click on your calibration ride and select “Find intervals…”.
A new window will appear. There are different methods to find intervals. Choose the Aero Test method and click on the Find button.Note: If the method is greyed out, it means you didn’t compute the ride. Do so, to be able to continue.
In the example, it found 2 intervals. You can add it to your activity and begin to analyze your data and find your calibration factor (Notio CdA Analysis chart).
It is possible that no intervals can be found. In that case, an error message will be displayed.
What is the Calibration factor?
The calibration factor results from the calibration of the Notio so that the pitot tube measures the wind as accurately as possible. The calibration factor is used in the calculation of the CdA and the wind. The way the wind comes into contact with ...
How should I perform a calibration run on the road?
Period of the day We recommend testing very early in the morning before the wind starts to pick up or traffic begins to develop. Location The chosen location must allow the athlete to accomplish multiple passes securely in both directions along a ...
How do we calibrate the Notio in an indoor velodrome?
Here are basics guidelines to calibrate the Notio in an indoor velodrome. Speed sensor In the indoor velodrome, a magnet-based speed sensor is recommended over a hub mount for better speed accuracy. Distance The recommended distance to calibrate the ...
Find velodrome laps
The Golden Cheetah functionality to “Find intervals…” has been improved by adding a method to find laps in a velodrome (still in beta). It can be used for outdoor and indoor tracks. It is based on the Notio sensors. First, you will need to compute ...
Do I need to calibrate the Notio before each use?
It is not necessary to calibrate the Notio before each test session. Once the initial calibration is performed and your new calibration factor replaces the default value of 1.39 in the app, there is no need to recalibrate the unit. However, for each ...
