VBVS Mac PT Overview

There are eight standard performance tests which can be selected within the scene designer. To add a test, click on the 'New' button. This will add the tests one by one in the order shown below:

Pressing ‘Remove’ next to a test will remove that test from the scene.

These tests can be assigned to any text elements. To add a performance test into a scene, click the ‘Text’ icon within the scene designer as shown below.

Within the right-hand panel, the parameter settings can be set to ‘Performance tests’ and then the desired test chosen.

Performance Test results will show as ‘Time taken’ by default. The following format options can be selected.

Once the parameter has been set as desired, the performance test will actively display on the video overlay.

Note that all on-screen performance tests will start in a stopwatch-style counter when the start conditions are met, and will freeze holding results on screen as soon as test end conditions are achieved.

Tests will be reset and started again after a completed test has been done when the start conditions for the test are met again.

To edit a performance test, select the test from the left hand list. The settings for this test will then be shown in the main view window.

Here, the start speed for the test can be set. If the ‘one foot rollout’ box is marked, this will fix the start speed to zero.

VBVS Mac PT Start of Test

This area allows the test end conditions to be defined. Either set an end speed, or distance value.

Marking the ‘beep at end test’ box will cause the HD2 to sound a single tone upon test completion.
 

VBVS Mac PT End of Test

Enabling this setting allows a mid-speed to be added to the test – for example ‘0 – 100 – 0’ tests.

When this box is marked, a speed value area will appear as shown below.
 

VBVS Mac PT Mid Speed

Note: Mid-speed is disabled when running speed to distance tests.

Use these two drop-down boxes to set the units of measurement used in the tests.
