GENERAL SAFETY INFORMATION
Intended Use
The M
™
Single Gas Monitor 0XL Series is designed to continuously monitor the ambient environment and
notifiy the user if the level of the target gas reaches the alarm set point for the dectector. The 0XL monitor
is a single gas monitor that is available in two versions to monitor either Carbon Monoxide (CO) or Hydrogen
Sulfide (H
S).

List of Warnings and Cautions within these User Instructions
Using a certified gas with a concentration other than the one listed for this instrument and sensor when
conducting a calibration or calibration verification test (Bump test) will produce inaccurate readings. This
means that higher levels of the gas being monitored may be present and could result in overexposure
and cause sickness or death. For proper use, see supervisor or User Instructions, or call M in U.S.A.,
-800-2-60. In Canada, call Technical Service at -800-267-.
Each person using this equipment must read and understand the information in these User Instructions
before use. Use of this equipment by untrained or unqualified persons, or use that is not in accordance with
these User Instructions, may adversely affect product performance and result in sickness or death.
This instrument helps monitor for the presence and concentration level of certain specified airborne gases.
Misuse may produce an inaccurate reading, which means that higher levels of the gas being monitored may
be present and could result in overexposure and cause sickness or death. For proper use, see supervisor or
User Instructions, or call M in U.S.A., -800-2-60. In Canada, call Technical Service at -800-267-.
Use only for monitoring the gas which the sensor and instrument are designed to monitor. Failure to do
so may result in exposures to gases not detectable and cause sickness or death. For proper use, see
supervisor or User Instructions, or call M in U.S.A., -800-2-60. In Canada, call Technical Service at
-800-267-.
Each time the unit is turned on, it performs a self-test, which activates the audible, vibratory and visual
alarms. If the self-test fails, or all the alarms do not activate, do not use. Failure to do so may adversely
affect product performance and result in sickness or death.
Immediately exit any environment that causes an alarm condition on the monitor. Failure to do so may
result in sickness or death.
Do not cover or obstruct display, audible alarm opening or visual alarm cover. Doing so may adversely
affect product performance and result in sickness or death.
Vibrator and LCD may not function effectively below – °F (–20 °C). Using the instrument below this
temperature may adversely affect product performance and result in sickness or death.
The following steps must be performed when conducting a calibration or calibration verification test
(Bump test) to ensure proper performance of the monitor. Failure to do so may adversely affect product
performance and result in sickness or death.
– Calibrate prior to initial use.
– When performing a calibration or calibration verification test (Bump test) only use certified calibration
gas at the required concentration level. Do not calibrate with expired calibration gas.
– A calibration verification test (Bump test) should be performed before each use.
– If the instrument cannot be calibrated, do not use until the reason can be determined and corrected.
– Do not cover or obstruct display, audible alarm opening or visual alarm cover.
– Ensure sensor inlet is unobstructed and is free of debris.
– Ensure calibration hood is removed prior to use.
WARNING
Do not attempt to clean the instrument by rubbing with a dry cloth. Cleaning with a dry cloth may generate
a static charge and result in an explosion if located in a hazardous environment.
Do not disassemble unit or attempt to repair or modify any component of this instrument. This instrument
contains no user serviceable parts, and substitution of components may impair intrinsic safety which may
adversely affect product performance and result in sickness or death.
CAUTION
This instrument contains a lithium battery. Dispose of in accordance with local regulations.
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may
permanently scratch the surfaces and damage the display window, labels, or instrument housing.
USE INSTRUCTIONS AND LIMITATIONS
IMPORTANT: Before use, each person using this equipment must read and understand these User
Instructions. Keep these User Instructions for reference.
Use For
Monitoring for Carbon Monoxide (CO) with the 0XL-CO monitor or Hydrogen Sulfide (H
H
S monitor.
2
Do Not Use For
Monitoring for gases other than those which the instrument was designed to monitor, or in atmospheres
where oxygen concentrations are below 2%. Prolonged exposure to high levels of target gas may
prematurely degrade sensor performance.
General Description
™
These User Instructions apply to the M
Single Gas Monitor 0XL Series, Carbon Monoxide (CO) or
Hydrogen Sulfide (H
S). It is designed to provide continuous monitoring of the ambient environment for either
2
Carbon Monoxide (CO) or Hydrogen Sulfide (H
The gas detected by the sensor installed in the instrument is identified on the label located on the front of
the unit. Accuracy of the instrument's gas sensor readings can vary up to ±2% depending on the accuracy
of the calibration gas, how often the instrument is calibrated, environmental conditions (temperature,
atmospheric pressure, humidity, air velocity), cross interference gases, or time of exposure to the target gas
(see SPECIFICATIONS section). Calibrating with the appropriate certified calibration gas prior to use, within
the same environmental conditions in which the instrument will be used, will increase the accuracy of the
instrument's gas concentration reading (see Calibration Verification Test and Calibration section). An internal
microprocessor controls the indication and alarm functions in response to the signals received from an
electrochemical sensor permanently mounted inside the unit. When turned on, it continuously monitors the
ambient air that enters the sensor through the sensor inlet opening by the process of passive diffusion. If the
level of the target gas detected by the sensor reaches a factory preset alarm point, the unit will alarm (see
SPECIFICATIONS section).
The 0XL monitor is a battery powered unit utilizing a permanently mounted, non-rechargeable .6-volt
Lithium battery. It is designed to be intrinsically safe. The 0XL monitor is CSA (US) certified intrinsically safe
for Class I, Div. I, Groups A, B, C, and D Hazardous Locations.
The components of the 0XL monitor are assembled in an ABS/PC plastic housing .2 x 2 x .2 in. (8. x
. x . cm). Located on the front face of the unit is an OFF/ON/MENU button, the display (LCD), sensor inlet,
audio alarm opening, visual alarm LED. On the back of the instrument is an alligator pocket/belt clip and a
label containing the intrinsic safety information and serial number.
