The last selected Deceleration test will be displayed after each power cycle. Speed parameters are used to start and end the test. Test results displayed on the screen of the VBOX Touch will remain on screen at the end of the test until the next start condition is met.


Speed units used are dependent on what is selected within the General Settings area.

The screen is split in two halves:

  • Left hand side: This includes a live speed display which always show the current speed of the vehicle, irrespective of any test start or end conditions. If the vehicle is traveling less than 0.5 km/h or satellite lock is lost (less than 4 sats), the value will display as 000.0.
  • Right hand side: This contains test information: Distance travelled, run number, time taken, average deceleration achieved, maximum deceleration achieved (g) and height difference. These values will start to populate once the start condition of the test is met. When the end condition is met, they will remain on screen until the start condition is met again. A test can be reset by pressing the Reset button at the bottom of the screen.

Note: If a battery is connected, the Current Test header will not include units.
