Basic steps for acceleration testing:
1. Connect sensors if you are using them.
2. Mount the VC4000.
3. Position the vehicle on the same incline as the test is being
performed.
4. Press the Acceleration key. Unit will zero adjust itself.
5. Select a test from the menu or Press Auto Start key for ¼
mile testing.
6. Accelerate up to the end point.
7. Use the arrow keys to scroll through the data.
If the Acceleration key was pressed while reviewing data from a
previous test, or if the zeroing setting was turned off, it’s not
necessary to come to a complete stop before pressing the
Acceleration key. The VC4000 will use the zero reference from the
previous test or if zeroing was turned off it will use the zero reference
established at the factory. See page 79 in setup for more details on
zeroing.
