Why has my VBOX not detected the end of the brake stop?

Possible causes:

1. Unsuitable environment or antenna placement causing noisy velocity data, so that the VBOX data never reaches 0.8 km/h.
2. Onboard filtering has been used which may be smoothing the raw data so much that the exact point in time that the car reaches zero cannot be detected.
3. The vehicle being tested is tall and has soft suspension. This can cause the velocity before the Rock Back to not go below 0.5 km/h. If this is the case, then look at the data in the graph screen to establish a minimum speed that the vehicle does reach before the rock back and apply this to the Report Generator test setup.
