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).
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 %. 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 0XLS Series, Carbon Monoxide (CO). It
is designed to provide continuous monitoring of the ambient environment for Carbon Monoxide. 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 ±% 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 0XLS monitor is a battery powered unit utilizing a permanently mounted, non-rechargeable .6-volt
Lithium battery. It is designed to be intrinsically safe. The 0XLS monitor is CSA (US) certified intrinsically
safe for Class I, Div. I, Groups A, B, C, and D Hazardous Locations.
The components of the 0XLS monitor are assembled in an ABS/PC plastic housing . x x . 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.
