CHAP. 7 - USE OF THE INSTRUMENT

ENGLISH
AGS-200
The leak check is mandatory and the software will prompt the user to perform the check
automatically every 24 hours. To Perform the leak check, bend the flexible sample
probe hose back towards the handle and press it firmly into the round air-tight socket
located on the plastic handle.
Press enter as instructed on the display to start the test. The pump inside the AGS will
start and run for approximately 10 seconds, after which it will stop and measure the
vacuum pressure for a further 10 seconds.
The operator can see the mbar vacuum pressure generated by the pump. The value
should rise to above 550 when the probe and pipework are correctly sealed. If the
system is airtight the value should remain for the duration of the check until the “LEAK
CHECK PASSED” message is shown. In this case the software will continue
automatically. If the value falls after the pump has stopped, then there is an air leak and
the leak check will fail. Using the indicated vacuum pressure, the operator is easily able
to locate any leaks in the external pipework.
If the problem persists then contact your local agent or the BOSTON technical
department.
