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.
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

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
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.
Fig. 2
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.
