Use of the "I" gas line option
For ASM 180 TD and ASM 180 TD+
• The detector DN40 inlet port (1) must be blocked.
• Connect the gas line under test (4) to the detector's 1/4"
VCR connector (2) via flexible connection components (3).
• Connect the reference leak (5).
• Connect the carrier gas flow control accessories
composed of a mass flow controller (7) or manual micro-flow
rate valve and stop valves (6) if necessary.
• Connect the carrier gas source via a flexible tube (8).
• A laminar flow must be maintained in the entire line under
test to obtain the expected result: the response time is
increased if a significant volume is between the carrier gas
supply and the detector.
• It is advisable to place the detector as close to the zone
liable to leak as possible.
• Purge the injection system with the carrier gas in order to
eliminate the air.
• It is better to stop the "gas line test" function in case of
autocalibration
Note: It is not necessary to connect a neutral gas purge to
the detector: the carrier gas acts in the same way as the
purge.
