7.3.6 Gas Evacuation
7.3.7 Tooling Disconnection
Same function as Tooling Connection but in revers order.
For information about this step, see on page 40.
7.4 Optimizing the Test Cycle
Test Cycle can be divided in six main blocks:
1 Connection of Tested Object
2 Pre Evacuation of Residual Air
3 Filling with Tracer Gas
4 Tracer Gas Leak Test
5 Removal and Venting of Tracer Gas
6 Disconnection of Tested Object

Gas Evacuation Setpoint Set desired level of Gas Evacuation.
-30 kPa (-0.3 bar, -4.4 psi) creates 30% vacuum,
which is adequate for most applications.
Extended Gas Evacuation Extends time for gas evacuation, after Gas
Evacuation Setpoint has been reached.
