Manual No. 22925, Rev. I, 04/18
4.9.2
Follow the steps in Section 4.6 Calibration
Testing, except use impurity-free test gas in place of 10
ppm gas. The alarm light will either remain
red
or turn
green
. Proceed as follows:
4.9.3
Alarm light turns
green
4.9.3.1
If the monitor is correctly calibrated and in
working order, the alarm light will turn
green
during this
test. This means the monitor was reading contaminated
air. DO NOT USE THE COMPRESSED AIR FOR
BREATHING.
WARNING
Do not breathe air that this instrument identifies
as toxic until the source of contamination is
identified and corrected. Breathing toxic gases
can cause death.
4.9.3.2
Identify the source of contamination. Do not
overlook the possibility that contaminated air entered the
compressor intake. The contamination could be from
engine or other exhaust entering the intake. If the source
of contamination is temporary, the monitor will return to
a non-alarm (safe) condition after the contamination is
cleared from the compressed-air system.
4.9.4
Alarm light remains red
4.9.4.1
If the monitor is out of calibration or not in good
working order, the alarm light will remain red.
4.9.4.2
Calibrate the monitor per Section 4.7 and apply
impurity-free gas per Section 4.9. If the alarm light
remains red, the monitor requires service. Refer to
Section 6.0.
WARNING
Do not use compressed air monitored by this
instrument for breathing unless the instrument
is in good working condition. Using a monitor
that is not in calibration or not working
correctly can permit undetected CO to enter the
breathing-air lines. Breathing toxic gases can
cause death.
5.0 GENERAL
MAINTENANCE
5.1
Care and Handling
5.1.1
This monitor is designed for portable, field use
and is not adversely affected by normal handling that is
required of any test and measurement instrument.
5.1.2
Transport the instrument in the passenger
compartment of the service vehicle.
NOTICE
Do not subject this instrument to extreme heat or
cold. Placing the instrument on the dashboard of
the service vehicle in direct sunlight or similar
conditions will elevate the temperature, which
will damage the instrument’s electronic
components. Temperatures at 0
o
F and below or
case temperature at 125
o
F and above will
damage the instruments components.
5.2 Cleaning
5.2.1
The need to open the case periodically to
calibrate the instrument exposes it to potential external
contamination. Take care not to introduce contaminants
into the instrument when the case is open.
5.2.2
Clean the exterior of the case with a solution of
water and mild detergent. Do not use solvent cleaners.
5.3
Calibration Test Schedule
5.3.1
Test the calibration when it is initially set up and
again the day after. Check it once a week for the first
month. Check it at least once a month thereafter. Refer
to Section 4.0 for test procedure.
5.4 Calibration
Schedule
5.4.1
Avoid the urge to calibrate the instrument.
Calibrate only when the calibration test shows it is
required. See Section 4.0.
5.5 Alarm
Tests
5.5.1
Although uncommon, alarm lights and horns do
fail. Check their function before each use by placing the
Run/Calibration toggle toward CALIBRATION. The
external alarm light will immediately turn
yellow
, and
within a few seconds the intermittent audible alarm will
sound. Placing the toggle in RUN position returns the
alarms to their normal operation.
Never use the
respirator without first verifying that the monitor is
in the operating mode; the exterior alarm light must
be
green
with no audible alarm.
