and then display:
4. Press the
Auto Start
key. The VC4000 will display 'Auto-
Start-Ready' and the current G reading.
5. Accelerate the car to the desired initial braking speed. After
reaching the desired initial braking speed, hit the brakes
hard and fast, applying maximum brake pedal pressure until
the vehicle comes to a complete stop.

Elapsed Time (E/T):
The time from when the VC4000 was
activated (see threshold page 65) until the
vehicle came to a complete stop.
Speed:
Speed of the vehicle when the VC4000 was
activated (see threshold page 65).
Distance:
Distance the vehicle traversed during the braking
time.
Distance (AdjD):
Stopping distance assuming the vehicle was
traveling at exactly the Brake MPH (usually
20) when the brakes were applied.
Avg. Gx:
Average longitudinal G force from when the VC4000
was activated to stop.
Avg. Gy:
Average lateral G force from when the VC4000 was
activated to stop.
Peak Gx:
The maximum longitudinal G-Force obtained from
activation to stop and the time where it occurred.
Peak ±Gy:
The maximum positive and negative lateral G-Force
obtained from activation to stop.
1
st
PkGx: The maximum longitudinal G-Force obtained from
activation to 0.75 seconds and the time where it
occurred. This is useful to determine if a braking
systems mechanical reaction time is sufficient.
