If the light-receiving part of the product, the measuring laser beam output port, the guide laser beam output port or the camera lens become dirty, wipe them gently with a soft, dry cloth so as not to damage their surfaces. To ensure correct measurement results, calibration should be carried out regularly (once a month or so). Any malfunctions or failures due to lack of calibration will be subject to repair even if the product is still under warranty. See page 47 for calibration instructions. Do not use kitchen detergent, polishing powder, thinner, benzene or ethanol. Do not scrub with a brush. The surface gloss, printing and writing will be lost or scratched. If the receiver or laser output port becomes dirty or scratched, accurate measurement may not be possible.

53. 52 8. Operations What is LDAM? LDAM is an acronym for Leak Detection And Maintenance and is the collective name for the functions of the entire system of leak detection and data recording. LDAM requires that a series of inspection records of critical inspection points and information about the equipment used for the inspection must be maintained. The product has an ‘LDAM mode’ specification to meet this requirement. The product's ‘LDAM mode’ is designed to extract, record and verify only the data recorded for the LDAM. When LDAM Mode is selected During the measurement, the product serial number is shown on the product display. On the cloud service side, there is a menu where only files captured for LDAM can be extracted and displayed.

For example, if is selected, an alarm beeping will be audible intermittently when the measured value is 100ppm-m or more, and the detection lamp will light up. When a reading of 500ppm-m (5 times the set value) or more is detected, the alarm sounds with a continuous beep and the detection lamp will light up. If is selected, the alarm will not sound (the detection lamp also does not light up). NOTE: The factory default setting is 100ppm-m. NOTE: The alarm setting point can be checked on the standby screen. For methane column density, see page 28.

Safety Precautions CAUTION

29. 28 5. Overview and principles 5.2 Principle The product detects methane based on near-infrared absorption spectroscopy using a semiconductor laser. A laser beam is emitted towards a detection point (gas pipe, ceiling, wall, fl oor, ground, etc.). The laser beam is scattered when it hits the detection point. A part of the scattered light is detected by the receiver of the product, and the total amount of methane between the product and the detection point is measured. The total amount of methane measured is expressed as the methane concentration (ppm) multiplied by the thickness (m), i.e. the methane column density (ppm-m). In principle, this product cannot detect gases other than methane (butane, propane, etc.). It is also not possible to detect gases beyond the reach of the measuring laser, for example behind walls or underground. Both detect the same methane column density. 100ppm 100ppm 100ppm×1m=100ppm·m 200ppm×0.5m=100ppm·m 1m 1m 200ppm 200ppm 0.5m 0.5m

44. 43 About measured and captured data: ● During measurement, the measured value is updated every 0.5 seconds. ● During measurement, the data is stored in the memory in every 3 minutes. The last data before terminating the measurement will be less than 3 minutes. ● The measurement data and the capture file are stored in the micro SD card together with the information of the measurement (or capture) date and time. If the device is connected to a smartphone, device location obtained from the smartphone will be added to the memory file. ● The built-in Micro SD card can store approximately 2,035 days of measurement data (approximately 13.7 kB for 3 minutes) alone, and approximately 65,000 times of capture files (approximately 21.2 kB per file) alone. ● When the capacity of the Micro SD card is used up, the product will delete the old measurement data and capture files stored in the SD card, and overwrite them with new data and files. 20210928140351_LMS2109002_+25.470167_+118.469034.txt Date and time Example of 28 September 2021 14:03:51 Serial number of this product Location information (Latitude _ Longitude) 8.

19. 18 4. Certi fi cations and Standards ■ Laser beam safety The measurement laser beam emitted by this product is classi fi ed as class 1 according to IEC 60825-1 speci fi cation. The guide laser beam is classified as class 3R according to IEC 60825-1 speci fi cation. The guide laser beam is dangerous to the eyes and should not be observed directly or aimed at other persons. Energizing the guide laser beam can also be seen on the display as “ ”. The Class is indicated on the label on the back of the product (see “ Speci fi cation of the laser beam” on page 19). Class 1 and 3R indicate the degree of danger with respect to the laser beam, as de fi ned in IEC 60825-1 as follows: Class 1 : Laser products that are safe to use for long periods of direct observation in the beam, even when using telescopic optics. Observation in the beam can still cause visual effects such as blindness, especially in dark surroundings. Class 3R : Although the level of radiant power exceeds the MPE for direct in beam observation conditions, the AEL is 5 times stronger than the Class 2 AEL (for visible lasers) or 5 times more powerful than the Class 1 AEL (for invisible lasers) and therefore the risk of failure is relatively low for these laser products. Because of the relatively low risk, the requirements for manufacturers and the control criteria in the national regulations for users are less stringent than for Class 3B. Laser products of class 3R are not regarded as intrinsically safe, but the risk is reduced. 4.3 Applicable Standards

9. 8 Always use the strap when using this product. Use the strap to prevent damage, malfunction or injury from the product being dropped.

41. 40 8. Operations If you detect methane gas... ● The measured value will increase. The measured value depends on the amount of methane gas and the distance to the measuring position. When there is a methane leak, the reading will rise sharply. If the measured value exceeds the alarm setpoint... ● The alarm will sound begin beeping and the flashing duration of the detection lamp will shorten. Refer to ‘Alert Value’ on page 48 for the alarm setting value. If the measured value exceeds the alarm setpoint by a factor of 5... ● The alarm will beep and the detection lamp will change from flashing to fully lit to indicate that an abnormal reading has been detected. The measured value is shown in red. If the measured value is displayed as a red dotted line −−−−− ... Measurement is no longer possible due to insuf fi cient light reception. Try a different method of measurement. (1) Shorten the distance to the detection point. (2) Look for areas where the guide Laser is re fl ected and facing the front.
