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
(flashing/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 larg
e 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 specific 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 reflective 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 off 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
or visible indicators.
