Gates® Carbon Drive™ Smartphone Application
The drive belt tension can be checked by using the
Gates® Carbon Drive™ Smartphone application,
which measures belt tension frequency.
The application is available for free to download at both the
Apple iTunes® store and Google Play® store. iTunes® is a
registered trademark of Apple. Google Play® store is a
registered trademark of Google.
Note: Perform belt frequency measurement on the lower belt
span, close to the center (between the sprockets).
Note: The application works best in a quiet environment.
Note: The following application instructions may differ between
phones.
1. Remove the key from the ignition switch.
2. From the application, click the Tension icon and Measure.
3. Confirm the phone’s microphone is ON (if applicable).
4. Hold the phone, so the microphone is as close to the drive
belt as possible (without touching the belt).
5. Pluck the belt with your thumb or a wrench (as shown) so
that it vibrates like a guitar string.
6. The microphone will measure vibration’s frequency.
