OPERATING INSTRUCTIONS

The following instructions are intended to serve as a guideline for the use of the M
Series. It is not to be considered all-inclusive, nor is it intended to replace the policy and procedures for each facility.
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-.
If you have any doubts about the applicability of the equipment to your job situation, consult an industrial

Display Readings

Normal Operating Mode

The LCD will display 0 ppm for gas levels below  ppm. Gas levels of  ppm and higher will be displayed in
increments of  ppm.

Performing Self-test

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.
A self-test can be performed at any time by pressing the On/Off/Menu button once from the normal operating
mode. This will test the battery, electronic circuitry and alarm functions to insure they are working properly.
The self-test does not test the performance of the sensor. This must be done through a calibration or
calibration verification test. See Calibration Verification Test and Calibration section of these User Instructions.
The self-test will be indicated by "test" icon being displayed on the LCD for about  seconds (Fig. ). The
buzzer, LED and vibrator will activate and then "CAL" will be displayed for  seconds (Fig. ). If the button
is pressed within  seconds of "CAL" being displayed, the unit will enter calibration mode (see Calibration
Verification Test and Calibration section). After successful completion of a self-test, the "check" icon (Fig. )
will appear on the display for 2 hours, and the unit will be in normal operating mode.
If a self-test fails, the LCD will display "Err" (Fig. 6). Press button to clear. Do not use the instrument until
the reason for the "Err" message has been determined and corrected.

Viewing Peak Levels

From normal mode, press the button twice and the peak reading will be displayed.
To clear the peak reading, wait  seconds; "Clr" will be displayed. Press the
button once to clear and the value will be set to zero so long as the unit is in a
non-contaminated environment (Fig. 7). The instrument will go back to normal
operating mode after  seconds.

Calibration Reminder Function

The unit has a calibration reminder function that can be enabled and disabled by the
user (factory default is enabled). When enabled, the "TEST" icon will flash when the
time since last calibration exceeds 0 days (Fig. 8).
In the event a user has a fixed calibration schedule less than every 0 days, the
calibration reminder function may be disabled. To disable this function: press the
button  times, the "Off/On" status will be displayed, wait  seconds until the "TEST"
icon begins to flash. To re-enable this function: press the button  times, the off/on
status will be displayed, wait  seconds until the "TEST" icon begins to flash.
Press the button to toggle between off/on. After  seconds it will return to normal mode.
