6.1 Cleaning of the Equipment
Your CPAT FLEX unit can be wiped clean with a damp cloth. Do not immerse the unit in water.
Avoid solvents and commercial cleaners.
6.2 Preventative Maintenance
The technician shall do periodic visual inspections on the RF connections and antennas
to make sure that there is nothing loose and that there is no rust. Both can affect the
performance of the system. Periodic inspection on the power cable shall be done to ensure
that the insulation is intact.
In case that a replacement is required, please contact Efgis for more information.
7. Quick Trouble-Shooting Guide
PROBLEM OR CONDITION PROBABLE CAUSES C0RRECTIVE ACTIONS
No leakage events detected Connection problem to vehicle
mounted whip antenna
Verify for continuity between
the center pin of the antenna
connector and the whip
antenna.
Check for humidity between
the whip and the base of the
antenna.
Verify for continuity between
the center pin of the antenna
connector and center pin on the
whip base.
Is DRV2 (3) connected to ARD4?
Check connection of USB cable
between ARD4 and DRV2 (3).
In-vehicle antenna
Check to ensure the monopole
antenna is connected to the
DRV2 (3) while inside the truck.
Ensure the monopole setting
is selected on the DRV2 menu
while inside the vehicle.
Detection frequency problem
Verify frequency at the head
end is not more than 4 kHz
offset from the DRV2 (3)’s
detection frequency.
Verify your location and validate
frequency area information
is correct (frequency, mode,
calibration factor).
Install a test point and conrm
DRV2 (3) detects correctly the
simulated leak in mobile mode
and then conrm the leak is
still detected when DRV2 (3)
is connected through vehicle
antenna.
System noise
Verify noise level at detection
frequency to note presence of
high noise levels.
For DRV3, it is possible to check
interference with the spectrum
view (available through its
menu).
Analog video carrier
Sync level may be too low
when video tag used.
Should be between -12 to -23
dBc, ideally -18dBc. The use of
a color bar generator with 87%
modulation is ideal.
