  • Page 16: Self Test

    Self test The RMLD-CS features an integrated function for carrying out a self test. This ensures that the RMLD-CS can provide accurate measurement data. A self test log file is automatically recorded and saved. NOTICE! A self test must always be performed before commencing work. The self test takes about 1 – 3 minutes. To perform the self test, proceed as follows: The RMLD-CS must be switched on and ready for use.

  • Page 17: Audio Modes

    If the self test was unsuccessful, what should be done? The most common causes of a failed self test are: ● The RMLD-CS was not placed correctly in the carrying case. − make sure the RMLD-CS is lying flat as intended in the com- partment in the carrying case.

  • Page 18: Real Time Mode

    3.6.2 Real Time mode Real Time mode is most effective when used over short distances and can be helpful in detecting low concentrations or in identify- ing the location of the highest gas concentration. In Real Time mode a continuous sequence of beats sounds as a function of the measured methane gas concentration. The quick- er the acoustic signal beat frequency, the higher the methane gas concentration.

  • Page 19: Using The Spotter Laser

    (here: AL 20). Using the Spotter Laser The green spotter laser is used for orientation, to indicate which area is being surveyed by the RMLD-CS. CAUTION! The spotter laser for the visible green wavelength is a class II laser product.

  • Page 20: Connectivity

    The OFF option is shown on the left-hand menu bar. After 1 minute, the spotter laser switches itself off automati- cally. If you wish to switch the spotter laser off manually: ● Select OFF.

  • Page 30: Detecting Methane Gas

    Detecting methane gas Functional principle The RMLD-CS makes it possible to detect methane gas from a safe distance. When IR light passes through a methane cloud, the methane absorbs a specific wavelength of the light. The de- tector detects the absorption due to methane in the reflected IR light of the laser. The signal is processed and displayed as the relative gas concentration expressed as ppm Direct sunlight and ambient light...

  • Page 31: Requirements

    Requirements For detecting methane gas using the RMLD-CS, three require- ments must be satisfied: ● The methane cloud and methane concentration must be great- er than the minimum sensitivity of the detector. ● The IR laser beam must penetrate the methane cloud. ● The target background (i. e. ground, buildings, etc.) must re- flect the IR laser beam.
  • Page 32 Note: Atmospheric air always contains a low level of methane. This natural background methane level is also measured by the RMLD-CS. The ppm-m measurement value therefore increases as the scanning distance is increased. Note: The shape of a methane cloud can be highly variable. Some leaks cause a high concentration directly at ground level without any measurable methane cloud above it.

  • Page 33: Start Measurement

    NOTICE! A self test must always be performed before commencing work. To perform a measurement, proceed as follows: 1. Switch on the RMLD-CS. 2. Select the desired display mode. 3. Use the spotter laser to select the area where you suspect a methane cloud may be present.

  • Page 34: Practical Tips For Detection

    Practical tips for detection Please note the following general points for all measurements: ● Use a smooth sweeping motion. ● If the target distance of the IR laser beam is approx. 5 to 7 m, ensure that the measuring point size in the target is large enough for good coverage. ● Scan pipework joints and valves as you approach them. ●...

  • Page 35: Measuring At Low Methane Gas Concentrations

    2. As far as possible, position yourself with the wind at your back at a distance of approx. 1.5 to 3 m from the meter. 3. Aim the beam initially downwards on to the ground. 4. Then sweep the beam upwards with an S-shaped motion along the pipeline. 5. If you suspect a leak underground, clear the area. 4.5.3 Measuring at low methane gas concentrations To measure low methane gas concentrations, proceed as follows: 1.

  • Page 36: Measuring From A Long Range

    4.5.5 Measuring from a long range The RMLD-CS can be used to determine methane clouds at dis- tances of up to 30 m. The actual maximum distance will depend on the characteristics of the target surface and the environmental conditions. As the distance is increased, the intensity of the laser light will become lower.

  • Page 37: Avoid Incorrect Measurements

    Obstruction The dark zone is not scanned. Fig. 26: Select the best angle to survey all areas during the measure- ment. Avoid incorrect measurements There are several conditions that may occur when using DMD audio mode that can lead to the algorithm giving a false detec- tion indication.

  • Page 38: Maintenance

    Maintenance A battery charger is included in the scope of supply of the RMLD-CS . Two slots allow two battery packs to be charged at the same time. WARNING! If lithium ion rechargeable batteries are defective there is a risk they can explode.

  • Page 39: Charging The Battery Pack

    AC/DC adapter. The RMLD-CS must be switched off to remove the battery pack. Charge the battery pack as follows: 1. Undo the two screws on the bottom of the RMLD-CS 2. Remove the battery pack. 3. Place the battery pack in the charger. Make sure it is fully inserted.

  • Page 40: Handling Faulty Lithium Ion Rechargeable Batteries

    Where transportation is permitted (e.g. by road or rail), it is subject to strict regulations. Faulty lithium ion rechargeable batteries must therefore always be removed be- fore shipping the RMLD-CS . Transportation by road or rail must occur in compliance with the current applicable version of the regulations.
