Sensor Accuracy
(After calibration)
Carbon Monoxide (CO) – Less than ± 5% of the displayed reading or 5 ppm,
whichever is greater.
Oxygen (O
) - Less than + 0.5% vol/vol from 7% to 4% Oxygen.
Hydrogen Sulfide (H
S) - Less than ± 5% of the displayed reading or ppm,
whichever is greater.
Non-contaminated
environment
An environment containing less than 0. ppm of hydrocarbons, 0.5 ppm of CO,
0. ppm of H
S, 0. ppm of Ammonia, 0.5 ppm of Hydrogen and 0. ppm of other
gasses not normally found in the air.
Certified calibration gas Refers to a calibration gas sold by M* or produced by an ISO 900:000
certified calibration gas manufacturer. The certified accuracy of the calibration
gas components must be listed on the calibration gas container and traceable to
National Institute of Standards and Technology (NIST) or a national measurement
institute standard reference material.
Warranty
years for sensor and electronics (see WARRANTY section)
* A gas analysis certificate of the calibration gas is available if requested.

OPERATING INSTRUCTIONS
The following instructions are intended to serve as a guideline for the use of the M
™
Single Gas Monitor 0
Series. It is not to be considered all-inclusive, nor is it intended to replace the policy and procedures for each facility.
If you have any doubts about the applicability of the equipment to your job situation, consult an industrial
hygienist or call M at -800-4-460. In Canada, call Technical Service at -800-67-444.
Activating the Detector
Press and hold the On/Menu button for seconds until the LCD displays “RLS”.
The instrument will go through a test sequence (test sequence may take up to 5 minutes on O
models).
Once the check icon is displayed, the instrument will remain on for two years.

WARNING
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.
