Page 8: Operating And Handling
Operating and Handling Always unscrew valve for a short time only. The leak outlet area on valve should not be touched, particularly not with your fingers or greasy objects. Retain the protection cap for the flange and fit it each time the test leak is removed. Caution The reservoir cylinder is pressurised. - Page 9 Fig. 1-2 Test leak TL 3-5 / 4-6, complete Pos.

Page 10: First Use Or Changing The Type Of Gas
First Use or Changing the Type of Gas Close all valves and the vent screw. Unscrew old test gas bottle. Remove protective cap from new test gas bottle. Screw in the new reservoir (hand tight) until to the stop. Fig. 1-3 Operating and Handling... - Page 11 Open the test gas supply on the reservoir (the knob turns downwards!) Fig. 1-4 The pressure gauge must now indicate the pressure of the gas bottle. Close the blocking valve on the reservoir (the knob turns upwards!). Fig. 1-5 Operating and Handling...

Page 14: Changing The Reservoir Cylinder Without Changing The Type Of Gas
Repeat process steps 6. to 10. twice so as to ensure that the gas reservoir in front of the test leak has been exchanged completely. The test leak will now be ready. The desired pressure can be adjusted with the venting screw. - Page 15 After removing the protective cap screw on the new test gas bottle. Fig. 1-11 Open the test gas supply. The manometer displays now the test gas bottle pressure. Fig. 1-12 1-11 Operating and Handling...

Page 17: Storage When Unused
Close the vent screw. Fig. 1-15 The Helium test leak is now ready for operation. Storage when unused Put the protective cap on the connection flange DN 16 KF and make sure that all valves and the vent screw are closed. Store the Helium test leak in a lying position or standing upright in the holder, protected against impact shock and high temperatures Maintenance It is recommended to retighten the union nut of the valve... -
Page 18: Applications
Applications Use for Vacuum Leak Detection The test leak TL3-5 / TL4-6 can be fitted by its DN 16 KF flange connection to any leak detector or any vacuum apparatus and can then be used for tuning the mass spectrometer as well as for checking response time and detection sensitivity. - Page 19 The leak outlet orifice itself is on the face of the sealed-in tubulation which is now visible. Fig. 1-17 Caution Clogging of the leak capillary. The size of the leak outlet orifice can change or get choked due to contamination Caution Do not touch the leak outlet orifice with the fingers or with greasy objects.
- Page 20 Caution When no longer using the test leak anymore always close the valve. The measured leak rate depends on the distance between sniffer tip and leak, and also on the speed at which the sniffer tip is moved past the leak. The size of the leak depends on the pressure as indicated on the pressure gauge and can be determined from the leak rate diagrams.

Page 21: Using Search Gases Other Than Helium
Using Search Gases other than Helium When using test gases other than helium, leak rates can only approximately be determined, the reason being that the 10 to 10 mbar·I/s range includes just the transition-flow region between molecular and laminar gas flow. Moreover, the individual flow profile of the respective capillary affects the conversion factor. - Page 22 Some values of dynamic viscosity in 10 Pa•s. R 134a 1,96 1,36 1,82 2,21 0,88 The resulting values must be used according to the predominant type of gas flow, i.e. for leak rates lower than 10 mbar·I/s mainly molecular flow and for leak rates higher than mbar·I/s mainly laminar flow can be assumed.

Page 23: Adjustment Of Leak Rate
Adjustment of leak rate The nominal leak rate was measured during production at a test gas pressure of 1 bar (abs.) vs. a pressure of lower than 1 mbar at the connecting flange and is shown on the label.
