Lite-Check CERTIFIER 1200 Operations Manual
Performing the Air Leak Test, when attached to a trailer or dolly:
1. Attach the EMERGENCY Air output glad-hand from the tester to the EMERGENCY glad-hand
port on the front of the vehicle under test (i.e. trailer or dolly).
WARNING: Failure to connect
the Emergency air can cause brake “compounding” and damage the brake chamber!
2. Attach the SERVICE Air output glad-hand from the tester to the SERVICE glad-hand port on the
front of the vehicle under test.
3. Perform the “Normal Power-up Procedure” detailed in the Appendix which starts on page 39.
4.
NOTE:
The default length of time this test will take (set by Lite-Check) is 60 seconds. We
generally recommend this setting not be changed. But, you may adjust it if needed by selecting
the “Settings” tab at the top of the Main 1200 Startup Screen which should be displayed on the
GUI right now.
Then see page 28 & 29 for how to navigate the Settings screen.
If you do
modify the settings, be sure to click on ‘Done’ on the Settings page to return the GUI to the
Main 1200 Startup Screen.
5. Fill in the “Trailer Information Panel” with the appropriate data. (This panel is the left side of the
Main 1200 Startup Screen. The VIN number is required, so enter the VIN number for this
vehicle. Enter the Customer and Order Number as desired. Click the drop-down menu inside
the “Calibration” selection box to select the correct “Configuration” of the vehicle under test. Do
not choose “Self Calibration”.
See page 24 for the “Configuration” choices available.
6. Click on “Start” in the Trailer Information Panel. The Air Leak test will start.
7. If the Internal Air Leak test
FAILS:
FAIL = >2 POUNDS SERVICE
FAIL = >3 POUNDS EMERGENCY
7a.
Select “Retry” on bottom right corner of Air Leak test page in the GUI.
7b. If it fails a 2
nd
time, pick “Cancel All Tests” on the left edge of the GUI.
7c.
Engage the EMERGENCY and SERVICE air lines to get air into the system. Soap-test
the blocked-off glad-hands, external fittings, and internal fittings as needed to locate the source
of the leak(s).
7d.
Tighten fittings and thread seal them as needed.
7e.
Select ”START” again (as in step 6). If this retry fails, call LITE-CHECK for assistance.
This is the end of the Air Leak Test when the tester is attached to a trailer or dolly.
