Operation 6 Operation With its small flange connection, pressure gage, and valves, the test leak is versatile in application. Sev- eral application options can be found in the following. Fig. 2: Closing the test leak Closing the test leak ► Always close test leaks at the diaphragm shut-off valve when not in use. 6.1 Using the test leak for vacuum leak detection Using its small flange connection, you can attach the test leak to any helium leak detector or every vac- uum system, and then use it for comparing the mass spectrometer as well as for testing the response... -
Page 17: Using The Test Leak For Over Pressure Leak Detection (Sniffer Test)
Operation Fig. 3: Open (left) and close (right) the diaphragm shut-off valve. Determining the detection sensitivity 1. Attach the test leak at the farthest point on the test object. 2. Close the diaphragm shut-off valve. 3. Using the vent screw, set the pressure gage pressure, so that the desired leakage rate still to be confirmed is output. - Page 18 Operation 4. For this purpose, read the correction factor depending on the pressure gage pressure and multiply it by the nominal leakage rate printed on the test leak. 5. Note the corresponding display once you have positioned the sniffer probe a defined distance from the leak.
