  • Page 7: Safety

    Safety Directions for Use 1.1.1 Use of this Manual This chapter describes the safety requirements which must be observed on all accounts when using the SmartTest Helium Leak Detector. All persons working on and with the leak detector must have read and understood the chapters relevant to their activities.

  • Page 8: General Safety Precautions

    General Safety Precautions 1.2.1 Use for the Intended Purpose The SmartTest Helium Leak Detectors serve for measurement and localization of small and very small leaks both on components and modules and on fittings and systems. They are suitable both for underpressure leak testing (vacuum method with or without partial current operation) and for overpressure leak testing (sniffing method).
  • Page 9 Warning The Helium Leak Detector SmartTest may not be operated in standing or under flowing or dripping water. The same applies for all other kinds of liquids. Avoid contact of the SmartTest with bases, acids and solvents as well as extreme climatic conditions.

  • Page 10: Responsibility And Guarantee

    Note Caution: Danger of injury Although this instrument is distinguished by high standards of quality and safety and has been built and tested according to the latest state of the art, injury or material damages cannot be totally ruled out in the event of misuse or use for a purpose which was not intended.

  • Page 11: General Safety Rules

    Maintenance personnel The maintenance personnel may operate the SmartTest leak detector in normal operation and perform maintenance work necessary for trouble-free operation of the instrument. In order to be authorised to maintain the SmartTest leak detector, the person concerned must have taken part in an initial training conducted by a Pfeiffer Vacuum employee or an experienced member of staff of the system user.
  • Page 12 Danger S TOP Caution: Mains voltage Improperly earthed products may be dangerous to life in the event of a malfunction. Connect the product in accordance with local regulations and earth correctly. Interruption of the earthed conductor inside or outside the instrument is not permissible.

  • Page 20: Measuring System

    Measuring System The measuring system consists (simplified) of: • a test connection • a backing pump • a turbo pump • a few valves • a helium sensor test rest connection helium sensor turbo pump test leak part A part B Gas connection for sniffing probe or venting line...

  • Page 21: Detection Principles

    Detection Principles Counterflow The sample is connected to the backing pump via valve V2. At a pressure p2 £ 15 mbar *) the valve V1 to the turbo pump is opened. Helium can get to the helium sensor through the two partial pumps A and B against the pumping direction.

  • Page 22: Leak Detection Methods

    Leak Detection Methods When searching for leaks with the SmartTest the test gas entering or escaping through leaks in the sample is detected. For gas to flow through a leak a pressure difference between the inside and outside of the sample is necessary. For this either excess pressure or vacuum pressure is generated inside the sample.
  • Page 23 Sniffing method In the sniffing method the test gas escaping from leaks in the sample into the atmosphere is detected. The sample must withstand the applied test pressure. In operation with the sniffing probe a constant gas flow is sucked in from the atmosphere.

  • Page 24: Test Gases

    Test Gases For reasons of economy and detection sensitivity He (helium with mass 4) is generally used as a test gas for leak detection. Under certain conditions, e.g. at increased He concentration on the sample, it may be useful to change to a different test gas such as He (helium with mass 3) or H (hydrogen, mass 2).

  • Page 25: Background Suppression

    Background Suppression The background signal may increase dependent on the measuring conditions (e.g. high percentage of helium in the ambient air). The background signal can be suppressed to enable easy measurement of small leak rates despite a high background. The background suppression can be locked or activated automatically with every START.
  • Page 26 Falling background Fig. 3-4 Falling background Item Description raw signal saved value displayed leak rate If the raw signal falls below the saved background value this is automatically set equal to the raw signal (e.g. at time t1). As soon as the raw signal rises again (e.g. at time t2), the saved background value remains constant.
  • Page 27 Fig. 3-5 Absolute measurement Zero constant function Fig. 3-6 Zero constant function Item Description raw signal saved value displayed leak rate By pressing the ”ZERO” key the momentary raw signal (e.g. at time t1, t2, t5) is saved as a background value and is then subtracted from the following measured values/raw signals.
  • Page 28 The automatic background suppression is locked. The zero value is retained after pressing the Stop key. Pressing the Zero key again overwrites the zero value. The zero value is set to ”0” at Power Off or changing the zero function. If the raw signal of the leak rate drops below the saved value/background value (see time: t3 to t4), it is not evaluated but the slightest detectable leak rate/detection limit is displayed.

  • Page 29: Manual Control Elements

    Manual Control Elements Instrument Operation The operating unit is the display, operation and control unit for the leak detector. Fig. 4-1 Functions of the buttons on the display START/STOP key The measuring process is started and stopped with the START/STOP key. ZERO key ZERO activates the background suppression in measurement mode.

  • Page 30: Commissioning

    Commissioning Installation, Assembly Note See the Chapter ”Technical Data” (Chapter 2) regarding the permissible ambient temperature, degree of protection, voltages, max. acceleration of the instrument in operation etc. Despite good attenuation and vibration decoupling of the mechanical pumps in the SmartTest, vibrations of the instruments can never be ruled out totally.

  • Page 95: Measuring The Internal Test Leak

    Measuring the Internal Test Leak This function is only available in the vacuum mode with mass 4. After running up the instrument the display changes to Ready to start! Fig. 6-89 Ready to start Softkey ”Test internal leak” leads to sub-menu: Fig.
  • Page 96 Fig. 6-92 The display also shows the default value of the internal test leak in addition to the measured test leak value: e.g.: TL: 8.3E-07 mbarl/s. Softkey ”Escape” always returns you to the menu: Ready to start Note Matching of the measured value of the internal test leak and the default value of the internal test leak does not mean that the measuring system is absolutely accurate if the internal test leak was used for calibrating the leak detector.

    Errors Errors are displayed by warnings and malfunction messages. Warnings point at a problem but you usually still can measure during that time. Measuring is no longer possible when malfunction messages are displayed. Warnings and malfunction messages are signalized by an audible alarm. It’s frequency is changing between 500Hz and 1200Hz every 400ms.
