GENERAL SAFETY INFORMATION
Intended Use
The M
™
Single Gas Monitor 0 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 monitor. The 0 monitor is
designed to operate for years and then be disposed of according to local regulations. The 0 monitor is a
single gas monitor that is available in three versions to monitor either Carbon Monoxide (CO), Hydrogen Sulfide
(H
S) or Oxygen (O
).
List of Warnings and Cautions within these User Instructions
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. With oxygen sensor
installed, misuse may produce an inaccurate reading where lower or higher levels of oxygen may be
present 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 a self-test is performed, it 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 °F (-0 °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 performing a calibration (O
test (CO and H
S models) to ensure proper performance of the detector. Failure to do so may adversely
affect product performance and result in sickness or death.
- When performing a calibration or calibration verification test (bump test) only use certified
calibration gas at the required concentration level. Do not use expired calibration gas.
- A calibration verification test (bump test) should be performed before initial and each use.
- If the instrument cannot be calibrated (O
models) is not within ± 5% of the calibration gas concentration 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.
- Insure 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.
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.
