Check for Leaks with Hand Probe

The ILS500 is now prepared for a manual test for external leakage. Use the hand probe
to check for leakage
1 Start by checking all connections between the ILS500 and your test object. Follow
each test line carefully and check every joint.
2 Proceed to check around the gas valves and manifold inside the ILS500.

Internal Leakage
The overall tightness of the manifold is tested using the pressure decay method. This is
a complement to the gas test, revealing leakage out, through the exhaust etc.
Possible results:
• No Internal Leakage
• Internal Leakage
Internal leakage can result in:
• False pressure and vacuum decay rejects
• Increased tracer gas consumption
