Using Road Tube
IMPORTANT:
For accurate bicycle data you must use mini tube with a
3/16 inside diameter. This does not mean you can use the large 9/16 OD
tubing with that small ID because bicycles are too light to make the pulse
needed.
These directions will assist you in placing your road tubes correctly on the
road surface with confidence and a minimum of effort.
Road tubes should be replaced on a fairly consistent basis.
Older tube
will eventually develop splits that can allow water to enter. When an air
pulse is received, this water can be forced back into the unit’s air switch,
potentially causing serious damage. Do not risk expensive repair bills by
trying to squeezing a few extra studies out of old tube. One rule of thumb
is to replace tubes after 30 days of use.
Installing Road Tubes
Proper road tube installation is very important for collecting accurate data
with your TRAX Apollyon Plus II. The road tube and the TRAX Apollyon
Plus II’s air switches comprise the sensing device for the unit. As with all
receivers, the sensor has to be functioning properly to record reliable in-
formation. With this in mind, examine your installations carefully and be
absolutely certain that your unit is recording data as programmed.
Step 1 – Select an Installation Location
The first step in the installation process is to select the location where the
road tubes will be installed. The tubes should be placed exactly perpen-
dicular to the flow of traffic and should be installed on a straight stretch of
road so that vehicles are not hitting the tubes on an angle.
For the best results, do not install the tubes in a location where traffic will
be queueing up and stopping on the tubes, or in a location where vehicle
will be turning over the tubes or otherwise striking them on an angle.
