The Deceleration Mode allows you to perform deceleration tests using either pre-defined configurations or your own specified values. You can access it by pressing the Mode button at the bottom of the screen and selecting Decel.

The previously selected Deceleration test will be displayed after each power cycle. You use speed parameters to start and end the test. The test results displayed on the screen will remain on-screen at the end of the test until the next start condition is met.

The speed units used in the test results depend on what you have selected in the General Settings area.

Decel Mode Overview

The Deceleration screen displays current and completed test information.

The screen is split into two halves:

Left-hand side: This includes a live speed display which always shows the vehicle's current speed irrespective of any test start or end conditions. If the vehicle is travelling slower than 0.5 km/h or the satellite lock is lost (less than 4 satellites), the value will be displayed 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. You can reset a test by pressing the Reset button at the bottom of the screen.

Note: If you are using the battery, the Current Test header will not include units to make space for the battery status indicator.

Selecting a Test

You can choose a Decel Test by pressing the Settings button on the bottom left of the screen. Preset and custom test options are then available on the right-hand side of the displayed screen.

The test that is currently selected will be highlighted and will be remembered for future use, even if you choose another mode.

Preset Tests

The Performance Box Touch has preset 5-speed Decel tests. Press a test to select it. The '60 – 0' test is selected by default.

200 – 0 (km/h or mph)

You can choose your own start and end conditions by pressing the Custom Test button on the bottom right of the test selection area.

Results screen sample

Tests will be displayed in chronological order and the fastest will be highlighted. To scroll through the results, use the scroll bar on the right-hand side of the screen.

Each new session will have a separate header, displaying the time and date for the first completed test in that session.

Information includes:

Test type
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)
Maximum deceleration achieved during a test run (g)
Altitude difference between the start of test and end of the test (m or ft)

You can take a screenshot of the test history by pressing the Screenshot button.

IMPORTANT -
If the unit is power cycled, up to a maximum of 127 tests will be remembered and displayed in chronological order. However, if more tests have been completed, they will still be recorded on the SD card.

To return to the main screen, select the Exit button on the bottom left of the screen.

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 at the bottom of the screen. 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 Performance Box 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.

Selecting the Reset button on the bottom right of the screen will reset all test results shown on the current screen. When you press it, the LEDs will briefly flash green twice and the unit will emit an audible confirmation notification.
