Tester Procedure
1. Connect compressed air or any inert gas to Tester.
(Inlet pressure to Tester can be between 50-175 PSIG (3.5-12 bar)
NOTE:
Step 1 must occur prior to connecting the Tester to power, or its screen will show
an error code “
n0A
” (no air connected).
2. Connect the Tester to power.
>
Within 20 seconds the Tester will automatically run a self-test and will self-calibrate.
>
Once calibrated; Tester’s display shows all zeroes.
3. Set desired system test pressure with Tester’s UP/DOWN arrows.
(Adjustable from 3 PSI to 43.5 PSI / 0.21 bar to 3 bar)
NOTE:
Step 3 must occur prior to pressing Tester’s ON button (step 5) or Tester will not
respond, since a test pressure command has not been set.
4. Use appropriate adapter and connect supply hose to system for test.
5. Press ON button.
>
MODE button toggles the digital display between PSI, bar and flow.
6. While system is filling, use white light to look for exiting smoke at leak points.
NOTE:
Smoke vapor exiting from a leak is even easier to see at low test pressures.
NOTE:
If possible, it is best to purge the ‘non-smoke’ air out of the system by leaving an
opening in the system being filled. Close the system once smoke exits that opening and
continue to fill with smoke. This quickly fills the system with Diagnostic Smoke®.
7. Once system is full, use UV light provided to look for UV deposit(s) at leak point(s)
>
The laser light provided will ‘see’ a leak by reflecting on the escaping smoke vapor.
NOTE:
After 10 minutes of operation Tester turns off and starts a pressure-decay cycle.
Pressure decay cycle can also be activated by turning Tester OFF at any time.
NOTE:
During decay mode, do not press either the UP or DOWN pressure arrows, or it
will interrupt the decay process.
NOTE:
After 8 minutes of non-operation the Tester goes into sleep mode. Pressing any
button wakes Tester up remembering the setting prior to sleep mode.
NOTE:
To completely turn OFF the Tester, remove power source.
DO NOT use the WV711 Tester in a vehicle’s fuel evaporative (EVAP) system!
DO NOT exceed normal system pressure in systems being tested!
DO NOT connect the Tester in such a way where its high pressure will be
introduced into the engine’s crank case system, or oil seals may be damaged.
