  • Page 4: Overview

    The RMLD-CS employs the same technology as the RMLD, known as Tunable Diode Laser Absorption Spectroscopy (TDLAS). As the laser passes through the gas plume, the methane absorbs a portion of the light, which the instrument then detects.

  • Page 18: Instrument Self Test

    RMLD-CS Operator Manual Instrument Self Test The RMLD-CS has a built-in function to perform a Self-Test of the laser wavelength. The self-test feature should be performed daily before survey to ensure that the instrument is operational. A Self- Test log file is recorded and stored on the RMLD-CS instrument.
  • Page 19 RMLD-CS Operator Manual NOTE: Laser wavelength drift is a normal characteristic of the RMLD-CS. Normally the rate of drift is low and will not affect the Self-Test if performed on a regular basis. Survey work conducted with an instrument which has drifted and was not self-tested may need to be redone. If instrument is not able to successfully perform a self-test after three attempts, contact HEATH for assistance.

  • Page 20: Audio Modes

    Real Time (Geiger) The Real Time mode of the RMLD-CS plays a variable (continuous) beep that is relative to the instantaneous concentration level. The faster the unit beeps, the higher the methane concentration level.

  • Page 21: Audio Warning Indications

    RMLD-CS Operator Manual The Real Time mode is most effective when used up close to help verify a low level detection or to help isolate the highest gas concentration. To verify a low level leak the following procedure should be used: 1.
  • Page 22 RMLD-CS Operator Manual If over saturation, the operator should back up from the target or point the device at a less reflective surface. Should the warning(s) persist, it could be due to a fault in the instrument. Check the display and follow the instructions in the troubleshooting guideline.

    Screen Mode - Image The IMAGE mode allows the user to view a live image of where the RMLD-CS is pointed as well as current and peak PPMM readings. This feature is especially useful in bright sunlight when the green spotter laser may be hard to see.

  • Page 43: Surveying With The Rmld-Cs

    The most important aspect to using the RMLD-CS is the proper control and aiming of the infrared beam. The first thing you will need to learn when surveying with the RMLD-CS is to control the aiming of the laser and rate of sweeping. Radical or abrupt motion may cause the RMLD-CS to give false detections due to rapidly changing distance or background that the laser detects.

  • Page 45: Long Range Scanning

    RMLD-CS Operator Manual Long Range Scanning The RMLD-CS can detect leaks from up to 100 ft. away. Actual distance may vary due to target surface and environmental conditions. As the scanning distance is increased, the laser light level returned will decrease. As the maximum distance is approached, a “low return signal”ytone is heard. You will need to move in closer.

  • Page 47: Dealing With False Detections

    RMLD-CS Operator Manual Dealing With False Detections While using the DMD mode, several conditions may occur that will cause the algorithm to give a detection indication. The most common situations are: Abrupt or jerky motions causing the scanning distance to rapidly change.

  • Page 48: How Does The Rmld-Cs Measure Gas

    How Does the RMLD-CS Measure Gas? With the RMLD-CS it is now possible to survey areas that are hard to reach or not easily accessible. The RMLD-CS does not have to be within the gas plume because it uses laser technology known as Tunable Diode Laser Absorption Spectroscopy.
  • Page 49 RMLD-CS Operator Manual meter in width, the RMLD-CS will measure 40 ppm-m, plus a background level of 15 ppm-m in this case, displaying a total value of 55 ppm-m. The infrared beam width is about 22”yat 100 feet. It is important to note that the laser beam “footprint”ywidth and distance increases as the distance increases (see Figure 4-5).
