Do notuse any force.> Do not store the product together with solvents. Do not use any desiccants.> Only use the device in closed, dry rooms and protect it from rain and moisture.> Carry out only the maintenance and repair work on thisinstrument that is described in the documentation. Follow theprescribed steps exactly. Use only original spare parts fromTesto.1.3.Protecting the environment> Dispose of faulty rechargeable batteries/spent batteries inaccordance with the valid legal specifications.> At the end of its useful life, send the product to the separatecollection for electric and electronic devices (observe localregulations) or return the product to Testo for disposal.32 Specifications42 Specifications2.1.UseThe testo 316-EX is a gas leak detector for the short-term detection of gases in areas at risk of explosion according to Directive 2014/34/EU (ATEX).Areas of application are the gas detection in rooms and the location of leaks at gas systems. The instrument is designed for use by trained personnel. For operation in areas at risk of explosion, also observe the Safety instructions document.Explosion limits of flammable substancesA flammable substance in the air has a lower explosion limit (LEL) and an upper explosion limit (UEL). The air/gas mixture isflammable anywhere between these two limits, potentially leading to an explosion (critical range). Below the LEL, the mixture is too lean for an explosion, and above the UEL it is too rich (non-critical range).The explosion limits depend on the substance:• Methane CH4: LEL 4.4 vol% / UEL 16.5 vol%• Propane C3H8: LEL 1.7 vol% / UEL 10.9 vol%• Hydrogen H2: LEL 4.0 vol% / UEL 77.0 vol%Restrictions of the application rangeDo not use the instrument as a monitoring instrument for personal safety! The testo 316-EX is no protective equipment!Do not use the instrument as a gas analyzer! The sensor detects almost all flammable gases to the same extent.2 Specifications5 2.2.

Getting to know the productSwitching onOnly switch on the instrument in fresh air as an automatic zeroing is performed at the end of the warm-up time. The ambienttemperature during zeroing should correspond to the temperature at the measuring location. If required, zero again manually at themeasuring location.When not in use for a long period of time, the sensor becomes contaminated due to oxidation, causing the zero point to become unstable. If the instrument has not been in operation for a long period of time (> 2 weeks), it must be switched on approx. 30‑45 minutes before use andthereafter zeroed manually.If the instrument has been stored at temperatures <0°C/<32 °F, it must be switched on 10 minutes before use and thereafter zeroed manually. > Push up on/off switch on the right side of the instrument. - T he sensor is warmed up (duration: approx. 60 s).During the warm-up time, the following information is shown in succession:• All segments light up.

Performing gas detectionCAUTIONDestruction of the sensor by external influences!> Do not expose the sensor to high concentrations of H 2S(hydrogen sulphide), SO x (sulphur dioxides), Cl 2 (chlorine) or HCl (hydrogen chloride).> Avoid contact between alkaline materials or water and thesensor.> Avoid the effect of moisture and frost on the sensor.Have the instrument calibrated by the manufacturerannually.Checking natural gas pipelines or hydrogen pipelines:Methane (the main constituent of natural gas) andhydrogen are lighter than air. The detection should takeplace above the line/the suspected leak.Checking propane gas pipelines: Propane is heavier than air. The detection should take place below the line/thesuspected leak, starting from the ground up. > Guide the sensor head as near as possible and at a low speed(approx. < 2 cm per second) over the components that are to be checked for leaks.- If the set alarm value is exceeded, the Alarm LED lights up red.If the acoustic alarm is switched on a warning tone also sounds,5 Using the product12the frequency sequence of which becomes faster as theconcentration increases.Manually perform zeroingIt is only possible to manually set the zero point if the gasconcentration currently detected is below 1000 ppm.Gas concentrations present at the point of the zeroing aresuppressed by means of the zeroing.

This can result in reduced sensitivity and falsified display of concentrations. If necessary clean the sensor.> Switch on the instrument, wait until the end of the initialization phase and switch off again. Repeat this procedure several times.â Clean the sensor head from the outside> If dirty, clean the sensor head with a soft dry cloth.â Cleaning the housing:> If dirty, clean the housing with a damp cloth (soap solution). Do not use aggressive cleaning products or solvents!â Switching on regularlyIf the instrument is used infrequently, deposits may build up on the sensor.Switching the instrument on prevents deposits building up on the sensor. Testorecommends switching the instrument on regularly to avoid deposits building upon the sensor.â Storage & transportationTo avoid contamination of the sensor, the instrument should not be storedor transported in an environment where there is tobacco smoke, foul air, oils,greases, silicones or evaporating liquids or gases. Any sensor that is contaminated as a result of storage or transportation must be cleaned before use, see Cleaning the sensor.â Regular servicing:Testo recommends yearly servicing of the gas detector by an authorized servicecentre.Tips and assistance10Tips and assistanceQuestions and answersQuestion Possible causes / solutions“Error 01” · I nstrument error: please contact your dealer or Testo customer service.“Error 02” · S ensor defective (wire breakage): please contact your dealer or Testo customerservice.“Error 03” · S ensor connection faulty: Steckverbidnung des Sensorkopfes prüfen Pleasecontact your dealer or Testo customer service“Sensor” blinkt · S ensor dirty: clean sensor, see chapter “Maintaining product”.If we were not able to answer your question, please contact your dealer or Testocustomer service.

小孔径连接件泄漏试验方法1、将小孔径连接件与目标过盈连接件或结构进行组装,以大约为 10 N/s1N/s 的速率施加a)70N士1N的轴向力,同时施加0.12 Nm002Nm力矩,或旋转不超过90、力矩从顺时针方向施加。
2、保持该组装力和力矩或旋转角度10s士1s。
3、在无任何锁合或解锁合机构的作用下,释放该施加的力和力矩。
4、将式样链接到LEY-T01鲁尔接头性能测试仪上，使试评价小孔径连接件和目标过盈/干涉连接件或结构以及管路(B.3616)的出口保持同一水平面。
5、仪器自动充水，直到孔或管路端有水滴落。
6、将注射器置于称重仪上,按下皮重键清零。
7、用水充入注射器。
8、对充水注射器在称重仪上称重,并记录该质量 m1,(注射器中水的重量)。
9、将充水注射器推入模拟配对连接件和止流夹的开口。
10、确定注射器和模拟配对连接件之间的连接在试验过程中没有水泄漏。
11、将称重盘放在称重仪上,按皮重键清零。
12、将称重盘放在孔或管路下方,这样使从管路出来的水收集到称重盘中。
13、慢慢推注射器芯杆使水在7s到15s内全部排出。
14、对装有从管部开口端收集的水称重盘称重，记录该质量 m2、这代表了没有从装配组件中泄漏的水。
