162 G-TECH / Pro Competition User Guide, Release 3.1
Glossary
Acceleration run: a procedure where the vehicle accelerates
from a stop when the G-tech is staged and ready to begin
timing. The staged G-tech starts timing the acceleration run
automatically when the vehicle begins moving. For more
information on acceleration runs, see “Measuring Your Runs”
on page 52.
Accelerometer:
a precision device which outputs an electri-
cal signal that changes under acceleration.
Calibration:
the process of teaching a device how to relate a
measurement of a system into a useful, quantified value.
Configuration Mode: One of two operating modes in the G-
tech. In this mode, all settings and configuration items are
entered.
Cornering Gs: see Lateral Acceleration.
Cornering Lights:
LEDs on the G-tech that illuminate when
lateral G forces of a specific value are exceeded.
Cornering Thresholds:
In the G-tech, there are two corner-
ing thresholds. The Low Limit is the smallest lateral G acceler-
ation value that turns on the cornering lights. The High Limit
is the lateral G acceleration value where the cornering lights
are blinking rapidly.
Deep Staging:
A fairly short rollout. On a track, to stage deep,
you would keep the vehicle rolling forward to within a few
inches of the stage beam. This gives the vehicle almost no dis-
tance to move forward and pick up speed prior to starting
the clock.
Distance Mark: An LED that comes on when a specific dis-
tance milestone (60 ft, 1/8 mile or 1/4 mile) has been
reached.
Drag Strip Mode: One of two operating modes in the G-
tech. In this mode, the G-tech allows the user to measure,
store and review performance-oriented data about a vehicle.
E.T.: Elapsed time.
Foul: Occurs when the user launches a vehicle too early, and
it crosses the starting line before it should.
