2 Introduction HS4000 is an ultralight and highly sensitive instrument that utilizes infrared laser to remotely detect methane leaks. HS4000 comes with Bluetooth capability that can transfer measurement data in real-time to the dedicated APP. Users can use the APP to check, record and export the data. Through the APP, users can generate detection reports using the saved data as well. 2.1 Working Principle HS4000 emits an infrared laser at 1.65 um. The laser beam travels to the target, is partially absorbed by the gas, then reected all the way back into the receiver. The reected laser is collected and converted to an electrical signal that carries information needed to deduce the relative methane concentration. The reading is expressed by a methane column density (ppm*m). It is the integral of the methane concentration (ppm) and the distance (m) on the optical path.

4.3 Instructions on the red dot sight Users can look through the red dot sight to achieve better aiming. The red dot sight is powered by the device . It automatically lights up after powering on the device. NOTE The sight is eective when aiming over 15 m away. If the distance from the measured object is too short, the red dot will not overlap with the green indication laser. If the red dot and the green indicator laser do not overlap when aiming for a long distance (>15 m), the red dot calibration can be performed by adjusting the knob on the sight. Figure 4.5 Red dot sight diagram If the red dot is higher than the green indication laser, turn the knob counterclockwise to make it lower; if the red dot is lower than the green indication laser, turn the knob clockwise to move it up. If the red dot is to the right of the green indication laser, turn the knob counterclockwise to shift it to the left; if the red dot is to the left of the green indication laser, turn the knob clockwise to shift it to the right.

4.6 Detection Do's and Don'ts 4.6.1 Case 1 When detecting through the glass, if the infrared laser is incident on the glass vertically, part of the light reected by the glass will be received by the device, which will cause light intensity saturation or inaccurate measurement result. In such case, please point as shown in Figure 4.6.B to avoid receiving the glass reected light. A B Figure 4.6 Do's and Don'ts when detecting through the glass 4.6.2 Case 2 Please avoid detecting through materials that have strong absorption or reection eect on the infrared laser, such as PMMA, laminated glass, anti-infrared glass. In such case, the methane concentration behind can't be detected or the measurement result may be inaccurate.

Figure 4.7 Avoid detecting through anti-infrared or absorbing infrared material 4.6.3 Case 3 When detecting towards the corner (or similar situation), as shown in Figure 4.8.A, the infrared laser may reect between walls, resulting in high measurement concentration. In such case, please point as shown in Figure 4.8.B to have the accurate measurement result. A B Figure 4.8 Do's and Don'ts when detecting the corner
