detector
Spray the reference leak (
5
) for a defined period (e.g. 5
seconds).
Note:
- the time required to obtain a signal on the detector (any
leak on the gas line will give a response
≤
this reference
time).
- the ratio read on the detector
Reference leak value
Helium signal value
(this ratio depends on the detector and the carrier gas flow.
Value: between 10 and 20).
Spray the various test points and according to the reference
time defined above, wait to go to the next point. It is
recommended to start on the detector side and to test
progressively by moving further away (increasing response
times).
Close the carrier gas injection.
Stop the test cycle by pressing
.
Deactivate the "gas line test" mode by pressing the yellow
