Zeroing On/Off
The VC4
000’s accelerometers are set to a zero G reference at the
factory on a
calibrated level bench
. When zeroing is turned off the
VC4000 will use the zero G reference instead of zeroing before a
test. It should be turned off only in isolated cases, such as when
zeroing before a test is not possible.
Default is on.

(PC) Accel Range
The accelerometer in the VC4000PC has 2 ranges; 2G and 6G. Use
2G for braking or acceleration testing to use the most resolution
possible. Use 6G for light impact testing. Speed and distance
calculations may not be as accurate if using the 6G range. The
range is for all 3 axes.
To set the Accelerometer Range:
1. Select

under acceleration or deceleration. This effect is slight and for the
purposes of the VC4000 is considered to be similar for all vehicles
designed to be driven on the highways including motorcycles,
passenger cars, semi-tractor trailers and most off road vehicles. The
