Tube Test
The Tube test allows you to check the quality of the air pulses that
are being received by the Apollyon from the road tubes. This test
should be performed once the TRAX is in the field and connected
to the road tubes to be used for the study. The test lets you identify
potential problems with the tubes, enabling you to take corrective
action.
When a pulse is received while in test mode, the strength of the
pulse is shown for about a second on the display of the TRAX. Pulse
levels are broken down into 4 categories: ‘X’ for Poor, ‘-’ for Fair,
‘G’ for Good and ‘!’ for Excellent.
In the example shown
here, the pulse strength
is excellent for the A, C
and D tubes. However,
the pulse strength for the
B tube is poor, indicating
that the tube should be checked, and possibly replaced.
Note that the Main Menu of the TRAX also contains a version of
this tube test feature, which assigns numeric values to the strength
of the pulses, ranging from 0 for no pulse to 9 for strongest pulse.
