Tube Test
The Tube test allows you to check the quality of the air pulses that
are being received by the Apollyon Plus II 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.
Refer to page 2-4 for more details.
Should you see a channel that is reading weak you can swap the
hoses on the nozzle to see if the weak signal follows the hose or
if it remains on the same channel. This will tell you if the weak
signal is an issue with the hose or with the counter.
If the weak signal follows the hose the issue is with the hose and
the hose should be replaced with a fresh one. If it stays put then it
could be an airswitch or some other hardware issue with the counter.
Press the DO or TAB key to exit the tube test screen.
