Performing A Calibration; Maintenance; Cleaning; Disposal - 3M 110XL Serie Directives D'utilisation

A calibration verification test (Bump test) should be performed before every use. This is done by checking
the monitor's response to a known concentration of certified calibration gas. Calibration of the unit must be
performed at least every 0 days or immediately if it does not pass a calibration verification test. Sensors used
beyond the warranty period or exposed to very high concentrations of gas may require more frequent testing.
Note: The instrument has been calibrated prior to being shipped from the factory. However, to ensure it is
performing correctly, a calibration or calibration verification test must be performed prior to initial use.
Performing a Calibration Verification Test (Bump test)
A calibration verification test (Bump test) should be conducted every time you use
the monitor. This is the only way to effectively confirm that all characteristics of
the monitor and the sensors are working correctly.
Ensure that you are in a non-contaminated environment before performing a
calibration verification test. To conduct the test, attach the calibration (cal) hood
on top of the sensor inlet. Ensure the calibration gas matches the sensor installed
in the instrument. Connect the hose from the gas regulator of the calibration gas
bottle to the cal hood (Fig. 7). Turn on the gas.
Compare the displayed values with those of your reference calibration gas source.
Apply the calibration gas for a period of at least 2 -  minutes to ensure sufficient
response time and steady state readings. If the measurement displayed is within
±0% of the calibration gas concentration, turn off the calibration gas and
remove the cal hood. The unit is now ready for use. Otherwise a calibration should
be performed.

Performing a Calibration

Ensure that you are in a non-contaminated environment
before entering calibration mode. From normal mode press
the button once; the self-test will be performed and "CAL"
will be displayed (Fig. 8). Press the button within  seconds
and the unit will enter calibration mode indicated by "000"
displayed on the LCD (Fig. 9). If the unit passed this
zeroing step, the display will change to "SPn" alternating
with "YES" (Fig. 20 & 2). Press button to complete
calibration with a gas span. Apply gas when the display
indicates "GAS" alternating with the expected gas level (Fig.
22). Apply the appropriate gas ( ppm for CO and 0 ppm
for H S) within 0 seconds.
2
Once the gas is sensed the display will read "SPn"
alternating with the expected gas level. The calibration
will take approximately 2 –  minutes. Upon successful
completion, the display will show the gas reading. Turn off
the gas and remove the cal hood.
If calibration fails, the "FAIL" message will be displayed
(Fig. 2). Repeat calibration steps. If the instrument still
fails to calibrate, do not use. Do not use the instrument
until the reason for the "FAIL" message has been
determined and corrected.

MAINTENANCE

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.
CAUTION
This instrument contains a lithium battery. Dispose of in accordance with local regulations.
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may
permanently scratch the surfaces and damage the display window, labels, or instrument housing.

Cleaning

Cleaning of the external surfaces is best carried out using a damp cloth with a mild detergent or soap.

Disposal

The 0XL monitor is designed to be discarded or sent back to a M Service Center to have the battery and
sensor replaced 2 years after initial activation. To properly dispose of the instrument, follow local solid waste
disposal regulations.

PRODUCTS, ACCESSORIES AND PARTS

Do not disassemble unit or attempt to repair or modify any component of this instrument. This instrument
