GENERAL SAFETY INFORMATION
Intended Use
The M
™
Single Gas Monitor 0XLS Series is designed to continuously monitor the ambient environment
and notifiy the user if Carbon Monoxide (CO) levels reach the alarm set point for the monitor.
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 over exposure
and cause sickness or death. For proper use, see supervisor or User Instructions, or call M in U.S.A.,
-800-4-460. In Canada, call Technical Service at -800-67-444.
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 carbon monoxide gas. Misuse may
produce an inaccurate reading, which means that higher levels of the gas being monitored may be present
and could result in over exposure and cause sickness or death. For proper use, see supervisor or User
Instructions, or call M in U.S.A., -800-4-460. In Canada, call Technical Service at -800-67-444.
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., -800-4-460. In Canada, call Technical Service at
-800-67-444.
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 -4 ºF (-0 ºC). 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.
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.
