Reaction Time (R/T):
The time from external trigger to the G-
Threshold. (Shows only if externally
triggered)
R/T Dist:
The distance traveled during the reaction time.
(Shows only if externally triggered)
Graphs:
Press the Graph/Data key to display graphs of the
run. Press Speed, Distance, G-Force, or Sensor
(PC). Press the same key again to scroll through
multiple graphs, such as G-Force or Sensor.
While reviewing the data after a braking test if the braking key is
pressed the VC4000 will start a new braking test using the zero
reference established the last time the Braking key was pressed
from the “READY” screen.
The VC4000 can be used to measure to a preset Time, Speed or
Distance.
QuickSet
™ is Vericom’s term for one button
programming for the ¼ mile. It assumes a ¼ mile acceleration run
so programming to 1320 feet is not necessary. The VC4000 records
data at 7 other distance points and 2 speeds (called Waypoints)
within the ¼ mile (
QuickData™
table).
To perform a preset distance test
1. Drive to the area where you want to take a measurement,
where the slope is the same.
2. To power on, press the
POWE R
key and hold for 1 second
until the unit beeps.
