Remote Detection for Increased Safety
The RMLD-FR uses highly advanced technology to detect natural gas
plumes from a remote distance. This makes it safer to scan in areas that
may be dicult to reach such as busy roadways, yards with dogs, fenced
o areas, and other hard to access places.
Tunable Diode Laser Absorption Spectroscopy (TDLAS)
The RMLD-FR employs Tunable Diode Laser Absorption Spectroscopy
(TDLAS) technology.
As the laser passes through the gas plume,
the methane absorbs a portion of the light, which the
instrument then detects. Based on the local meteorological
conditions, a given amount of gas escaping from the ground
will produce a plume that varies in size and uniformity of concentration
levels. The plume, by nature, is variable and dependent on the soil
conditions, temperature, wind, and leak rate.
Features
The RMLD-FR includes many features which reduce costs and improve
usage. These advanced features include, but are not limited to:
- User Interface - highly optimized
for First Responders
- Internal Data Logging
- WiFi
- GPS
- Bluetooth BLE
- Color Camera
- Color Display
- Spotter laser
- Self Test
- Light Weight
- Rechargeable and Replaceable

What if the instrument
failed the Self Test?
The cause is most often due to:
- instrument not properly
positioned in the case
- case was moved during test
- laser wavelength has drifted
- battery level is too low
Ensure sucient battery
charge before attempting
Self Test procedure.
Make sure the instrument
is in its proper position,
all the way down, and at.
After rechecking the above,
repeat the Self Test procedure.
The instrument has a built-in function to perform a Self Test
of the laser wavelength. Perform the Self Test daily before
scanning to ensure the instrument is operational.
A Self Test log le is recorded and stored on the instrument.
To access the stored les, refer to pages 18-20.
Self Test
Self Test takes 1-3 minutes
No yearly factory
calibration required unless
instrument repeatedly fails
the Self Test or presents
other problems.
CAUTION: Should the instrument
not pass after several attempts,
do not use the instrument for scan
work until the problem is corrected.
CAUTION: Do not attempt to
repair the instrument. Should the
instrument not work properly,
or indicate a fault or warning,
refer to the troubleshooting
section of this manual.
NOTICE: Laser wavelength drift
is a normal characteristic of the
RMLD-FR. The rate of drift is
normally low and will not aect
the Self Test if performed on a
regular basis. Scan work conducted
with an instrument which has drifted
and was not Self Tested may need
to be redone. If instrument does not
successfully perform a Self Test
after three attempts, contact
HEATH for assistance.
CAUTION
1. Turn on the instrument and
allow it to successfully boot up.
If the instrument does not nd a
successful Self Test report for the
day, a pop-up message appears
on screen. Press the OK button to
continue. (There is no pop-up
message if a successful Self Test
report is found for the day.)
2. Press (long press) and release the
MENU button.
3. Select the Self Test option.
The screen will display and guide
the next steps for the Operator
to follow within 10 seconds
(enough time for the steps).
4. Place the instrument in its
designated area in the carrying
case, making sure it is all the
way in place and at.
5. Result of Self Test is indicated
by audible tones:
One (1) beep every second
means instrument passed.
Two (2) beeps every second
means instrument failed, and
Self Test should be repeated.
If instrument fails on a third
attempt, contact Heath
Consultants Factory Service.
Result of Self Test is indicated
on the display. A Self Test le is
also created.

DMD (Digital Methane Detection)
Digital Methane Detection (DMD)
is a highly sophisticated detection
algorithm that greatly enhances the
use of the RMLD-FR. The factory de-
fault setting for DMD is Enabled (on).
While using DMD mode, an audio alarm
will be heard, and on-screen indicators
(ashing/color-changing readings
and screen border) will be seen when
methane detection occurs.
DMD will indicate detection when
the PPM-M exceeds the Alarm Level,
or when the reading is excessive.
While the low light warning is sound-
ing, the RMLD-FR may still be able to
detect very large gas concentrations,
indicated by frequent, fast beeps.
The adjustable Alarm Level controls
the DMD. Your department’s scan-
ning procedure may require the use
of a specic value or procedure to
set it. Set the Alarm Level such that
the false detection rate is low, while
not too high that leaks are missed.
Please refer to page 10 for detailed instrucitons on performing a Self Test.
Audio Warning Indications
The instrument emits a constant
beep to indicate instrument-level
warnings and/or fault conditions.
A warning will also be displayed
on screen. The most common
warnings are:
- Low signal return/low light level
- Over saturation of signal
- Low battery
If low signal return/low light
occurs, then change angle or
move in closer to get in range.
If over saturation, then back up
from the target or point the
device at a less reective surface.
Should the warning(s) persist in
the instrument, check the display
and follow the instructions in the
troubleshooting guide on page 25.
To turn o DMD mode:
- Press the MENU button
- Select AUDIO MODE
- Select Disabled
NOTICE: DMD Mode will enable
automatically after 5 minutes,
enabling audible and color
border indicators.
NOTICE
WARNING
WARNING: When DMD is
disabled, the instrument
will not alarm with audible
