Used for displaying the braking force on a TV. The QB.4 Android app runs on an Android stick that is plugged directly into the TV. The app is operated via a small remote control. This means that any television can be used to display and control the app, without any licenses, activations or intermediate PCs. Includes power supply unit, remote control and accessories.
Measure pedal force and transmits data wirelessly at 433Mhz. The pedal force meter allows the application of the same pedal force across multiple measurements. This is particularly useful for all-wheel-drive vehicles when left and right wheels are tested individually.
