Utilities Menu
The Utilities Menu contains an assortment of operations that are necessary
and/or helpful to the operation of
the TRAX Apollyon. Press the
TAB key until UTILS is flashing,
then press the DO key to enter this
menu. When you have selected
UTILS from the Main Menu the
screen shown here is displayed.
Note: The nonvolatile memory in the TRAX Apollyon will retain the default
settings you program. These settings will be used for future traffic studies
without having to re-enter them.
Tube Spacing
The Tube Spacing selection allows you to set the proper tube spacing
for the tube layout you will be using. When collecting data that will
be processed for speed or classification, you have to use a tube layout
with at least two road tubes set at a fixed distance apart (L5, L6, L10,
L11, L12). It is by knowing what this fixed distance is that speed and
classification can be determined.
The currently set tube spacing is
shown. To change this, use the
TAB button to select
Sp: and
press DO. The screen shown
here will then be displayed.
There are two values that are typically used for this spacing with the
Apollyon:
2.0 ft
if you are using traditional
road tubes
(like mini-
tubes), or
0.3 ft
(4 inches) if you are using the
EZ Belt
. (Each EZ Belt
contains two tubes connected at four inches apart by a thin layer of
rubber.)
Set the Tube Spacing to the value you will be using by pressing the
numbers on the keypad. If you are using the EZ Belt, enter 0.3 by
pressing 0, 0, 3. If you are using traditional tubes, enter 2.0 by press-
ing 0,2,0. Once the correct number is entered, press DO to return to
the Utilities menu.
