Description of the Invention: [Technical Field] The present invention is a conventionally known method for detecting at least one property of a gas and a conventional manufacturing method for manufacturing such a sensor element. For example, the sensor element is designed to detect a physical and/or chemical property of the gas in the "measuring gas chamber." A particular focus of the invention described below is to detect the composition of the gas in the measuring gas chamber, in particular to detect the proportion of the gas component of the measuring gas chamber, for example the partial pressure and/or concentration of the gas component, the gas component is particularly May refer to oxygen. In particular, the sensor is used to detect the air value of the exhaust gas of an internal combustion engine. Such sensor elements are often referred to as sputum probes. λ probes (which can also be manufactured by the method of the invention in the scope of the invention) are exemplified by the "sensors in the car of R〇bert B〇sch", 2007 edition, pages 154 to 159. In particular, the X sensor element can be a so-called time point λ probe. In particular, the method can be: manufacturing and conditioning (Konditionierung, English: c〇ndiu〇ni = and = single sensing elements (they do not have integrated heating elements), for example: kiss unheated λ probe. In the case of 'such probes are used as low = probes for the purpose of two-wheeled vehicles', for example as sensor elements, sensor elements that are used as a mouthpiece in a housing (field or as a complete probe) (This point is also referred to below as "sensor") [previous technique] The m is not heated. In many cases, after the probe is constructed, the reaction time is on Μ (thin (4) (4). The official is willing to use this t2 timetable. _产卜.response time) t2 is too long. 1 The table is not required for the λ probe in the burner frame - 201105961 For use in oily milk (fertilizer) (Fettgas, English: fat (four) or Order (5) Daizhou) operation to replace the oil-free gas (痩 gas) (Magergas, English: thin gas) after the operation of the probe voltage from the mV to the time ... ... In addition, when the sensor Where the component is built into the test frame multiple times and then measured, in many cases, the reaction time &a Mp; can not be reproduced or difficult to reproduce. Therefore, people hope that the right 铱彳忐 叩 有 has a new sensing | § ,, the reaction time t2 is shorter than the traditional sensor components, the full length of the sundial and reaction The time t2 can be stabilized (there is a repetitive aspect). Therefore, the present invention provides a method of conditioning a sensor element of the above kind, which at least greatly avoids the conventional manufacturing and conditioning methods or utilization. The disadvantages of these methods of manufacturing and conditioning sensor elements, construction sets, and sensors. This method is used to include at least a sensor element, or a construction group containing sensor elements, or - Sensor component: sensor for conditioning. As mentioned above, the term "structure group" is fixed here; at least one sensor component in a housing, and the "sensing," device is free A completed operative structural element comprising the other components of the structure w and the month b, such as a connector. The term "conditioning" is used herein to refer to a process within the scope of the invention, in the course of which The measuring component is prepared for use, this In particular, it can be used for one purpose: to measure the sense, the JL 7L as a mutual and reproducible measurement industry, for example, to remove impurities (contaminants) caused by specific manufacturing steps (they will be ~1) Thus, the conditioning system comprises a process which is achieved at or after the manufacture of the sensor component. Accordingly, the conditioning process 4 201105961 can be partially made (but at least partially operational) On the sensor 7C, for example, a sensor element without a housing, a sensor element (construction group) in the housing or on a fully fabricated sensor. The work can be part of the manufacturing process. Corresponding to this, a manufacturing method can be provided, which comprises the conditioning method described below, but the conditioning method can also be implemented separately in the stepwise construction of the sensor, or in the case of complete fabrication, for example in a separate The test rack is implemented and/or has been implemented at the end of the complete use location (eg in a car). The sensor element is for detecting at least one property in a "measurement gas chamber". In this regard, for example, reference may be made to the above description of the conventional sensing II 7L device, in particular, the sensor element may be a sensor element without an addition, that is, a heating element without integration. Sensor component. As described above, such a sensor element can be particularly applied to the use of a two-wheeled vehicle, in particular, the sensor element can be a single crystal cell (einzellig, one-cell sensor element) The sensor τ, which has a "measuring unit cell", has, for example, a "jumping cell" (outer (3) is called "..., English: jump cell" or a "measuring unit cell" called a jumping cell. However, it can basically be other designs of the sensor elements, details of λ, for example, reference to the above description. Xiaobei is a sensor element that can be a two-point λ probe. Basically, it can also manufacture a multi-cell sensor element or a sensor element that works according to other measurement principles; for example, a broadband sense Detector element 0 The manufacturing operation provided at least in the method described may itself be performed by the method of the method, so that only one of the measuring unit cells is provided, which measures a part of the unit cell, but may also measure the unit cell separately in one The assignment is part of the above paragraph g 201105961. As mentioned above, the conditioning method can also be carried out on a sensor that is only partially fabricated. However, the completion of the sensor must be such that the measurement unit cell described above can be provided, and the measurement unit cell can be operated at least partially. The measuring cell has at least one first electrode and at least one second electrode. Here, the first electrode can be applied with gas from the measuring gas chamber, and the operation can be performed directly or indirectly, for example, the first electrode can be directly applied to the gas of the measuring gas chamber, and/or via a porous layer. The gas permeable sheath is indirectly applied with gas, but if this method is not used (or in addition to this method), it may also be considered to apply the gas from the measurement gas via one or several "access canals" (Zutritskana). The gas of the chamber, for example, can pass through and/or diffuse through the channel to the first electrode or along the opposite side 2 from the electrode to the channel. For example, the second electrode may be connected to a "reference gas space". For example, the reference gas space may be identical or partially opposite to the gas-measuring member, but may also be completely or partially with the tear. The gas chambers are separated. If the second electrode is connected to at least one reference gas space. The reference gas space is designed to be spaced apart from the measurement gas chamber, and the gas spectrum space, particularly a reference channel, is particularly preferred. For example, it is a reference air passage that is connected to the engine compartment of an internal combustion engine and is separated from an exhaust gas quantity [in which the composition of the gas mixture (e.g., female gas value) is to be measured]. In addition, the measuring unit cell has at least one solid electrolyte, and the solid electrolyte is connected to the first electrode and the second electrode H. "Solid zero-solution" (which is preferably a ceramic electrolyte) means a material 1 material at least at a high temperature (For example, at 60 (temperature above rc and preferably at least 8 = °c), there is ionic conductivity to one or several ions (e.g., oxygen ions). 1 For example, a conventional solid electrolyte material can be used herein, for example. Use 6 201105961 (Yttrium) to stabilize the dioxins (ySZ). However, if this material is not used (or in addition to this material), other solid electrolyte materials such as sharp (Scan (jiuln) stabilization) can be used. Zirconium dioxide or other kind of solid electrolyte. The sensor element may contain other components not mentioned above in addition to the "measuring unit cell". As mentioned above, for example, the sensor element is The measurement unit cell may contain other unit cells, and is correspondingly designed as a single crystal cell (Einzeller 'English: one_celler) or polycrystalline cell material (Mehrzeller, English: multi-celler). It is operated in the form of NernstzeUe (NernstzeUe), that is, in the form of a jumping cell, but can basically be used as a pump cell (Pumpzelle). In the operation of the cell mode, the sensor element may have an associated control and/or analysis circuit, but the circuit may also be wholly or partially a component of an external device (the sensor is separated from the sensor element). In general, reference may be made to the prior art. In addition, the sensor elements can be constructed into a probe housing. For example, the measurement unit cell can be made in a layer configuration, and preferably in a ceramic layer configuration. For example, the layer structure can be enclosed by a protective tube, such as a metal manifold, in particular having a slot through which gas can exit the measuring gas chamber, for example from an exhaust passage of an internal combustion engine. For example, the layer structure can be configured such that the first electrode and the second electrode are arranged to overlap each other or adjacent to each other. It is particularly preferable to design the first electrode as an outer electrode of a seed layer structure... The two electrodes are designed to be inside In addition, the sensor element may comprise one or several sealing elements (described in more detail below), such as one or several sealing discs and/or sealed packages. For example, 'for example' Reference may also be made to the prior art 201105961, such as Robert Bosch's "Sensor in the Car", version 2〇〇7, 156 157 百v'. The sensor elements described in this document can also basically be used with the present invention. Method of manufacture and/or conditioning. According to the invention, the measuring unit cell is subjected to a conditioning process prior to the sensor element entering the operation. In the conditioning process, the measuring unit cell is subjected to a conditioning temperature. It is also possible (〇pti〇nal) to apply a conditioning current to the measurement cell during the conditioning process. Here, "increased conditioning temperature" basically means a temperature above room temperature, and is at 200. (: The above temperature is particularly preferably higher than 3 〇〇 <> c. The conditioning temperature may be at least 800 ° C, and preferably at least 90 〇 π, particularly preferably at least 1 〇〇〇 C. To do this conditioning The procedure should preferably use an external heater which is not a component of the sensor element itself, in particular one or more of the following heaters can be used: an electric heater, in particular an electric heater of a thermal resistance winding, for example An electric heater that completely or partially encloses the sensor element and/or some of its parts; a heatable sensor holder, in particular one or several sensor elements for the valley Heatable socket (SchHtz); a flame, in particular a gas flame; a heated gas. In this conditioning procedure, at least one sealing element of the sensor element (for example a disk shape) Sealing element and/or a sealed package) Verglasen ^ In this case, it can be used in particular for one or several types of sealing 70 parts: a sealing element comprising at least one glass component and/or a glass component Component, especially a boron nitride Sealing element; a talc porcelain (Steati® (ceramic containing a large amount of talc) component) containing at least one glass component. This case is shown. An example: the proposed conditioning procedure can be part of the method of manufacturing the sensor element. In this case, application 8 201105961 plus the increased conditioning temperature is also used as part of the manufacturing operation of the sensor element, as vitrification is part of the manufacturing process. 'That is the case. This conditioning temperature can be carried out especially in a certain gas atmosphere. At least one or several components are known. The conditioning procedure can be carried out in a gas atmosphere containing oil (fett, English: fatty or (10)... 'i should be carried out in the air burned by the oil fuel, in the gas mixture, and/or in a gas atmosphere in which the oil-containing and oil-free gases are alternately changed. The certain gas atmosphere is particularly known. The gas composition of the air value (Luftzahl), such as air and / or especially oily gas (Fettgas) ^ if this method is not adopted (or In this way, it is also possible to carry out the conditioning process in a gas atmosphere of a modified type (WeChSelnd), for example, the gas value in the gas atmosphere is changed from the air value of the oil-free (mager'ying: thin). To the oil-containing two gas values or vice versa, from an oil-containing air value to an oil-free air value. There may also be a sequence of several air changes... plus him (1) (= air # oil-free air). This conditioning procedure In particular, the following may also comprise a plurality of partial steps 'in the at least one partial step using a -first gas atmosphere (for example an oil-containing gas atmosphere) and in at least one second partial step using another - a gaseous atmosphere (eg, a species that does not contain a body atmosphere), or vice versa. Gas (Brennerprtifstand ‘英:burner test sUnd) is implemented. The term "burner test stand" generally refers to a device in which the at least one device or a portion of the sensor (eg, the at least one test cell or 4 201105961 a sensor element including the test cell) And at least one of the structural groups comprising the sensor member is subjected to heat generated by the burner and/or subjected to a flow of air generated or affected by a burner. If this method is not adopted (or in addition to this method), a gas atmosphere can be applied. Aa In addition to applying the measured unit cell to an elevated conditioning temperature, as described above, the conditioning cell is also subjected to a conditioning current during the conditioning process. Even if the measuring cell is operated in a cell mode when the sensor element is operating normally (ie, there is no current, and only the potential between the at least two electrodes is tested), it can also be used in the conditioning process. This conditioning current is applied. In particular, at least one partial step of the conditioning procedure (eg, in the conditioning procedure 2-part-part step) selects the conditioning current such that the second electrode is rolled, rolled and due to a pumping procedure by the first The electrode (e.g., the outer electrode) flows to the first electrode (e.g., the inner electrode). As described above, the conditioning program may also include a plurality of steps, wherein the measuring cells are each applied with a staghorn in at least two partial steps. For example, a conditioning electric muscle for the direction of the 丨A a. j € machine, the amount of the conditioning current is 1 mA, 士-士士, 0-5 mA, and preferably at least 1 mA, especially at lmA~3〇mA Between, if v will measure the unit cell, apply lmA~3() mA first. In the second part of the step of the knife step, the unit cell will be measured in the opposite direction - the middle of the conditioning current between bA and -30 mA), then the current - the conditioning program (especially the conditioning program Preferably, the program may be at least 1 second, and preferably between 5 seconds and 90 seconds, during the step of the procedure, the program may be specifically combined with the test sequence for at least 3 seconds. The conditioning program is Yiji Pile Force 咕...

Furthermore, the oxidized material layer can also be removed from the electrode surface and can be used in this way. The electrodes are made more sensitive in the low temperature range. With these measures, either alone or in combination, the sensor elements can be used well in the form of unheated sensor elements.

The measuring unit cell and/or the structural group can thus be subjected to a low temperature measurement in the atmosphere of the oil-containing gas at a temperature of at least 800 ° C (and preferably at a higher temperature) (ie before the sensor element enters the operation). )heating. If this method is not used (or in addition to this method, the other A 201105961 can also measure the unit cell and / or the structural group containing the unit cell at a temperature of at least 800 ° C (and preferably at a higher temperature) The alternating atmosphere of the gas is heated 'especially before the low temperature measurement', that is, when the sensor element enters the operation. Also, if this method is not used (or in addition to this method), the measurement crystal can also be used. Applying a current to the structural group comprising the measuring unit cell, in particular applying a current on the at least one first electrode and/or the at least one second electrode at a temperature below 800 〇c or at least 800 〇C a temperature range (and preferably more) is applied to the at least one first electrode and/or the at least-second electrode. When the measuring unit cell is heated by the outside (especially a structural group containing the measuring unit cell) When a front zone is heated, a high temperature is also expected in the area of the at least one sealing element (for example, the area of the at least one sealed package). In this manner, the heating process can also be performed when the program is properly performed (generally heating The program is necessary for the CSD intensity [CSD: characteristic shift-down: the signal movement caused by the intrusion of the oil-containing gas component into the reference area] by vitrification (for example, boron nitride sheets in a sealed package) And the heating process is generally referred to as the heating program AH. The embodiments of the present invention are shown in the drawings and are described in detail in the following description. [Embodiment] FIG. 1 shows a burner test stand in a schematic manner ( 11 〇), using it to illustrate the method of the present invention. The burner test stand (11〇) comprises a casing (112), the casing (112) has a conditioning chamber (n 4). Conditioning room (H 4) accommodating a sensor element (116) in the form of a finished product or intermediate product. In this embodiment, the sensor element (116) comprises a measuring cell (1 18), [12 201105961 measurement The unit cell (1) 8) may be provided in a state in which the method of the present invention has been functioning, for example, in the form of a layer of a fire, a layer, and/or a structure comprising the unit cell (118). Other components of the sensor element hand (116) For example, a housing element, a sealed package, a connector or the like. The measuring unit cell (118) comprises a first electrode (12A), which in this embodiment is designed as an external electrode and can be protected by a porous The layer (i 22) is supplied with gas by the measuring gas chamber. Further, the measuring unit cell (118) comprises a second electrode (丨24) which is designed in the form of an internal electrode and which is formed inside a layer of the measuring unit cell (118). Is separated from the measurement gas chamber. Here, the second electrode (124) is formed in a reference channel (126) and, for example, air can be applied via the reference channel. The first electrode (120) and the second electrode The electrodes (124) are connected to each other by a solid electrolyte (127). For example, the solid electrolyte (127) can be yttrium stabilized dioxin (YSZ). The electrodes (120) (124) may be connected to the circuit via an electrode and/or apply a current (herein indicated by IB) and/or a voltage. In the conditioning chamber (114), the "measuring unit cell" (118) may be subjected to a conditioning current, such as with an associated current source. This conditioning current (which is indicated by IB in Figure 1) is preferably controlled and/or regulated and may alternately have a positive sign (±). The control means (34) should preferably be designed such that it affects the conditioning current Ib, in particular its direction and/or its size and/or its length. For example, the entire burner test rack (1 1〇) is designed to be computer controlled. Further, in the embodiment shown in Fig. 1, the burner test stand (11) preferably includes a heater (130). If not (or in addition to this), the burner test stand (110) may also include a gas supply means (132). Through this gas supply section, the conditioning chamber 〇 14) can be applied with an accurately defined "total atmosphere" (GesamtatmosphSre, total atmosphere). [S 2 13 201105961 Other designs, such as those detailed below, are also possible, for example, some juices may be used, with the housing (112) and/or gas supply means (132) being omitted. In addition, the shovel s-frame (11 〇) may include a control means (13 sentences, for example, the burner test rig (1) 经由 can be completely or partially controlled via the control means (134), for example In other words, the current supplied to the electrode (12) (124) is controlled and/or the function of the heater (130) and/or the control gas supply means (132) are controlled. In the proposed method, a conditioning procedure is carried out, in which the following method steps can be carried out individually or in combination: • Before the original cryogenic measurement, ie in the sensor element (1) Before, the unit cell (11 8) and/or other components of the sensor element (丨丨6) are heated in an atmosphere of oily gas at a temperature higher than 800 t; • high in an alternating atmosphere of gas The other elements of the unit cell (118) and/or the sensor element 〇16) at 8 〇 (the temperature of rc (especially before the low temperature measurement, ie before the sensor element (16) enters the operation) Heating; • applying a current to the measuring unit cell (Π 8) and/or other components of the sensor element (116) over a temperature range of less than 8〇〇〇c on the first electrode (120); • at the first electrode A current is applied to the measuring unit cell (118) and/or other components of the sensor element (116) at a temperature range above 8 〇〇 «c. The reaction with the oil gas component can be carried out in the experiment to the 85 〇t burner test stand. This reaction has occurred in an oil-laden atmosphere, but the reaction is enhanced by alternately supplying an oil-free gas (Magergas) with an oil-bearing gas and increasing the temperature. One possible measure is therefore to heat the measuring unit cell (118) in the absence of oil gas and/or in air, in particular to heat the front sensor region. Here, only the protection of the tube area (which may also include a winding of the sensor element (116)] is meaningful. For example, for individual sensor elements, this can be achieved with a winding heater (13〇), or for a number of sensor elements (116) or a number of cells (11 8). The electrically heated slot is reached and the measurement cell (118) or sensor element (116) can be inserted into the slot. Alternate replacement of oil- and oil-free gas operations, in the simplest case, uses a gas flame change. In theory, it is also possible to make changes using electric heating, in particular using barreled gas (bottled gas) (Flaschengas, English). Substantially the entire set of components of the sensor can be heated, including the housing and the sealing element, but it is particularly advantageous if only the area of the measuring cell (118) is heated. This is limited by the following conditions, for example, because the sealed package of the sensor element (116) is thermally unstable, such as a sealed package of talc porcelain (Steatit) at over 72 (rc in many current sensor elements) Damage will occur if it exceeds 720 ° C. If it is not heated by the heater (130) (or in addition to heating with the heater), a conditioning current heating can be applied to enhance the heating, and the conditioning current is therefore also This may be referred to as "test current supply." In the case of high temperatures, this may result in a desired change in the electrode configuration of the first electrode (120) and/or the second electrode (124). In the oily atmosphere in the conditioning chamber (ιΐ4), helium causes the oxygen to move away from the boundary layer of the neighboring electrode to the electrode (12〇) or (124), not only to transport oxygen from the gas. In many cases, the important point is the load of the outer electrode (12 〇). This means that the direction of the current should be chosen such that the first outer electrode (4 〇) is at a low potential and the inner electrode (124) is at a high potential. And oxygen is to be taken from the exhaust gas or by the conditioning chamber (ιΐ4) Into the reference channel (126). Therefore, the initial external electrode (12〇) must be inside the electrode (12 sentences lower electricity. So, due to less oxygen, the electrode and electrolyte 咍 $ 15 201105961 boundary area will cause Material destruction. In the second step, this region is regenerated due to the reversal of the current direction. For a typical probe, the useful value measured is 30 mA for 30 s. For the reaction (Rtickreaktion: English: Back-reaction) is -1mA for 30 seconds. Overall on "go (正
向)反應」(Hinreaktion,英:to-reaction )時,1 mA〜3〇mA 的電流使反應時間改善。在此,回反應的參數一般不改變, 回反應不得對正向反應作補償作過頭。對應於此,對於回 反應’有用的電流區間(Strominterval,英:current interval ) 為0 A A〜-30mA。舉例而言,施加電流的期間,對各個部 分步驟係可為3 0秒’換言之,對各反應路徑為3 〇秒,對 於各個部分步驟’換言之,對各反應路徑,有意義的時間 區間’舉例而言’係在5秒〜90秒之間。依目前的理解, 在施電流時’由於固體電解質(127)的晶格發熱,故需要有 充分的離子傳導性。因此之故,廢氣溫度或者在調理室(114) 内的溫度宜大於800°C。對於感測器元件溫度在施電流時, 重要的參數一般為測量晶胞(118)的内電阻。在施電壓時, 17歐姆的内電阻一般可造成高度改善。這一點典型地相當 於廢氣溫度〔或調理室(114)内氣體溫度〕約1097 °C以及電 極溫度約908°C。對應於此,宜使用至少8〇〇。(:的電極溫度, 且且更咼。然而,基本上也可在低溫範圍用少於°c的極 溫度施加電流。 在圖1中所示的實施例,要實施此方法係使用為此本 身ex a十的燃燒器測试架(110)。但如果不採用此方式(或者 除了用此方式外同時另外)也可在已用過的感測器元件(116) 上實施此方法’例如在第一次進入操作前,在一個使用在 16 201105961 一内燃機廢氣通道上的感測器元件(116)上實施。所提議的 措施可在已建構的感測器元件(116)上及/或在未建構的感 測器元件上實施。然而如果這些措施在未建構的感測器元 ,件(16)上實施,則這些措施_般不再能將㈣物質的蒸氣捕 獲(這些毒性物質係在建入程序時才帶入者)。而且要變 換這些措施,亦即實施本發明的方法,基本上可以在已安 褒完成的感測器⑴6)上,在制於—裝置(例如内辦機女 特別是内燃機的廢氣通道)中之前或之後實施。舉例而言, 該方法可在已安裝完成的感測器元件(116)〔例如具有 的電纜束(Kabelbaum ’英:cable harness)者〕上實施。 旦此處特別是由於高溫所致’當程序進行不良時 纜束扣傷。對應於此,宜在一分別的測試架中實施此方法, 例如在圖1的燃燒器測試架(1 10)中。 【圖式簡單說明】 圖1係用於將一感測器元件作調理的本發 圖。 π々凌的 【主要元件符號說明】 (110) 燃燒器測試架 (112) 殼體 (114) 調理室 (116) 感測器元件 (118) 測量晶胞 (120) 第一電極 17 201105961 (122) 多孔隙的護層 (124) 第二電極 (126) 參考通道 (130) 加熱器 (132) 氣體供應手段 (134) 控制手段 Ib 調理電流 18In the case of "reaction" (Hinreaktion, English: to-reaction), a current of 1 mA to 3 mA improves the reaction time. Here, the parameters of the reaction are generally not changed, and the reaction cannot be over-compensated for the positive reaction. Corresponding to this, the useful current interval (Strominterval, English: current interval) for the reaction is 0 A A to 30 mA. For example, during the application of the current, each partial step can be 30 seconds 'in other words, for each reaction path is 3 〇 seconds, for each partial step 'in other words, for each reaction path, a meaningful time interval' is exemplified Words are between 5 seconds and 90 seconds. According to the current understanding, since the lattice heating of the solid electrolyte (127) occurs when the current is applied, sufficient ion conductivity is required. Therefore, the temperature of the exhaust gas or the temperature in the conditioning chamber (114) should be greater than 800 °C. For the sensor element temperature when applying current, an important parameter is generally to measure the internal resistance of the unit cell (118). A 17 ohm internal resistance generally results in a high degree of improvement when voltage is applied. This is typically equivalent to the exhaust gas temperature (or gas temperature in the conditioning chamber (114)) of about 1097 °C and the electrode temperature of about 908 °C. Corresponding to this, it is preferable to use at least 8 inches. (: the electrode temperature, and more ambiguous. However, it is basically also possible to apply a current in the low temperature range with a pole temperature of less than °c. In the embodiment shown in Figure 1, the method is implemented using this for itself Ex a ten burner test rack (110). However, if this method is not used (or in addition to this method), the method can also be implemented on the used sensor element (116) 'for example Prior to the first entry operation, it is implemented on a sensor element (116) that is used on an exhaust passage of an internal combustion engine on 16 201105961. The proposed measure can be on the constructed sensor element (116) and/or Implemented on unconstructed sensor elements. However, if these measures are implemented on unconstructed sensor elements, (16), these measures will no longer be able to capture (iv) the vapor of the substance (these toxic substances are It is only brought into the process when the program is built in.) And to change these measures, that is, to implement the method of the present invention, basically on the sensor (1) 6) that has been installed, in the device (for example, the internal machine) Female, especially the exhaust passage of internal combustion engines) Before or after. For example, the method can be implemented on a sensor component (116) that has been installed (e.g., with a cable harness (Kabelbaum's cable harness). This is especially due to the high temperature. When the program is bad, the cable is buckled. Corresponding to this, the method should be implemented in a separate test stand, such as in the burner test stand (1 10) of FIG.
