4. ARD2 1 00 Remote Methane Leak Detector User Manual 1 Warnings Before using the instrument, you must read the instruction manual carefully and strictly follow the s teps to operate and maintain! The handheld detect or has two lasers. When the device is turned on, the detect or laser is invisible and continuous. By pressing the switch button on the device, the green spotter laser can be turned off. The green indicating laser level is C lass 3R. Protect your eyes from di rect exposure ! Laser specifications D etect or laser : Maximum output power :≤10mW Wavelength: 1653nm Laser Class: Class 1 Spotter laser : Output power : ≤5mW Wavelength: 530nm Laser level: Class3R, direct exposure is potentially dangerous, avoid direct exposure to eyes

Maintenance project Frequency Wipe the exterior surface of the instrument with a damp cleaning clot h Often Clean the window of the handheld detector with an alcohol - ba sed glass cleaning cloth When the window has obvious dust and pollutants Calibration Once a month Charge End of each use

17. ARD2 1 00 Remote Methane Leak Detector User Manual 14 ☆ Common m isuses The detect or laser is facing the sky, and the light signal cannot be returned; The detect or laser is directed at the glass at a vertical angle, and the optical signal interferes, causing a false alarm. Therefore, there must be a certain an gle with t he glass when testing through the glass; During the detection, the moving speed is too fast, causing a sudden change in the signal and easily causing false alarms; The detection distance is less than 1 meter. At this time, the laser optical syste m is in a poor state. Try to avoid measuring in this state. ☆ When there are factors that cause rapid gas diffusion, such as high winds and high temperatures, the gas cannot be concentrated, which affects the detection effect. Operators should consider similar situa tions in actual operations. ☆ ARD2 1 00 Remote Metha ne Leak Detector can detect methane leakage at a limit distance of 100 meters. The actual detection limit distance will vary depending on the environment. The longer the distance, the weaker the reflected l aser energy and the lower the accuracy of the dete ction result. When abnormal changes in the alarm value are found at a long distance, you should move to a close distance and check carefully. ☆ When the detect or laser is blocked by some objects, the distanc e will be abruptly changed, and false alarms may occur.

16. ARD2 1 00 Remote Methane Leak Detector User Manual 13 4.4.2 Detecting When the laser emitted by the device passes through the natural gas leaking air mass, the methane gas will absorb the laser. The absorbed laser l igh t is received by the detector through diffuse reflection, and the concentration information of the methane gas leakage is obtained through data collection and processing. Column density of m ethane (ppm ﹒ m) = methane concentration (ppm) × air mass thickness (m). ☆ I n order to ensure that the ARD2 1 00 Remote Methane Leak Detector can properly detect methane gas, the following conditi ons must be met: There is methane gas accumulation in the laser path; Th e laser can pass through the gas; The laser can be reflected back to the receiver through the reflective surface; ☆ During the detection operation, the moving speed of the handheld det ector will also affect the detection result. Please observe the followin g points during operation: You should try to maintain a uniform moving scan; Focus on the detection of leaking valve ports, exhaust ports, cracks, etc .; When the position of the pipel ine is known, detect according to the S - shaped scanning path;

5. ARD2 1 00 Remote Methane Leak Detector User Manual 2 1. Introduction ARD2 1 00 Remote Methan e Leak Detector uses international advanced tunable diode laser absorption spectroscopy technology (TDLAS), which can detect methane gas within a certain distance. At the same time, through optimization design and independent research and development, the detection distance and accuracy of the detector are greatly improved, which is the most powerful safety guarantee for gas inspection and leak detection. Unlike traditional portable detectors, this Remote Methane Leak Detector do es not need to place the p ro be in a gas - filled environment. Instead, the device emits a laser beam. The laser passes through the pipe or the space above the facility and hits the object at the other end. Reflected back to the receiver, and then converted into electrical signals, th es e signals are used to analyze the concentration of metha ne, the unit is ppm ﹒ m. By using WMS technology, the ARD2 1 00 Remote Methane Leak Detector can achieve extremely high detection accuracy. The light at this wavelength is only absorbed by methane, so it only reacts to methane and is not affected by other gase s, which greatly impro ves the accuracy of detection. Using the Remote Methane Leak Detector , the operator does not need to be in a dangerous environment, which not only protects the safety of the inspector, but also can inspect the overhead pipeline from a long distance, which improves the inspection efficiency. The detection reading is the product of the concentration of the laser passing through the methane gas mass and the thickness of the gas mass in ppm ﹒ m, as shown below:

12. ARD2 1 00 Remote Methane Leak Detector User Manual 9 The distance can be set from 1 t o 10, corresponding to the ARD2 1 00 detection distance from near to far. For example, when measur in g a nearby pipeline or other nearby unknown leaks, you can set the distance value to 1 to improve near - site measurement accuracy; when detecting a distant leak or a high - rise building, you can increase the distance value to increase the detection distanc e. Responding speed: Use the + and - keys to change the response speed. Press MENU to confirm the changes and return to the main menu. The distance setting can be set to "fast", "medium" and "slow", correspondin g to the response speed of ARD2 1 00 from fast to s low. Unit setting : Use the + and - keys to change the unit setting. Press MENU to confirm the changes and return to the main menu. Unit setting can be set to "ppm", "% LEL" or "% VOL". Language setting : Change the language setting with the + and - keys. Pres s MENU to confirm the changes and return to the main menu. The language can be set to "Chinese" or "English". 4.3.3 Voice setting:

15. ARD2 1 00 Remote Methane Leak Detector User Manual 12 4.4 Detecting Methods 4.4.1 Aiming instructions The ARD21 00 Remote Methane Leak Detector has two aiming methods to assist d etec tion. The first is a green spotter laser. The green spotter laser is suitable for short - range aiming and aiming in weak sunlight. The second is a sight lens , which is suitable for long - distance sighting and sighting in strong sunlight. ☆ Indicating la ser aiming After the device is turned on, the spotter laser and dete ct or laser are turned off . Short press the power switch on the front of the device to turn on the spotter laser and detect or laser at the same time. ☆ Sight lens use effect When the devic e is turned on, the sight lens is also open, and when the device is turned off, the sight lens is off at the same time. The specific aiming effect is as follows: ☆ Sight lens deviation adjustment When deviation of the sight lens is found, the accuracy can be corrected by adjusting the crews in up dan down direction or left and right direction.

19. ARD2 1 00 Remote Methane Leak Detector User Manual 16 ☆ When the laser passes through a thin PE pipe, the detec t or laser may penetrate the PE pipe to detect the methane gas in the pipe, and the pipeline detection should be avoided at this time. 4.4. 3 A larm I nformation A larm of concentration When the ARD2 1 00 Remote Methane Leak laser detects a methane gas (ppm ﹒ m) that exceeds a set threshold, it will send an audible alarm signal thro ugh a buzzer, and the alarm value will be displayed on the LCD. light intensity is too weak / too strong alarm When the reflected li ght signal received by the ARD2 1 00 Remote Methane Leak Detector is too weak or too strong ( detection accuracy cannot b e guaranteed), the LCD screen displays "light intensity too weak / light intensity too strong". Temperature control fault alarm When the ARD2 1 00 Remote Methane Leak Detector detects a problem with the internal laser temperature control (which will cause inaccurate detection and affect its life), it will display a temp erature control failure on the LCD screen. 5. Common P roblems and S olutions ☆ Unable to detect known methane gas When the device does not display any alarm information, but cannot send an alarm when the known methane gas is detected, you should use the gas chamber provided with the device for calibration. For the calibration method, refer to section 4.3.3. ☆ Temperature control failure
