- Time of first completed run in session
- Date of first completed run in session
- Test run number
- Test completion time
- Test completion distance (km/h or mph)
- Maximum speed achieved during a test run (km/h or mph)

IMPORTANT
Up to a maximum of 127 tests will be displayed in chronological order, however, if more tests have been completed, they will still be recorded on the SD card. Once the limit has been reached, a warning message will be briefly shown, advising that further tests will not be saved to the Test History. The message will show again if the unit is power cycled. A 'TEST HISTORY FULL' notification will also be shown beneath the Live Speed display. To view new test history results, press the Reset Button.
Save Results
You can also save the results as a .txt or .csv file (dependent on the option selected) to the SD card by selecting the Save Button. When pressed, the unit will emit an audible confirmation notification. If the results have been saved unsuccessfully, for example, no SD card is inserted or the card is full, the button will flash 3 times and VBOX Touch will emit an audible error notification.
If saved successfully, the file name will include the test type, the date and also the time, taken from the first completed run in that session. Along with the test history information described above, the results file also includes average acceleration information, as well as the latitude and longitude position (in degrees and decimal degrees format) added to the session header.
