3.2.5
If the instrument goes into any alarm mode (any
annunciator light is any color other than
green
or any
audible alarm) after the warm-up, re-initiate the warm-up
by terminating and restarting power. If the ARMED light
is not lit, or the ALARM light is
yellow
with an intermittent
horn, proceed as follows:
ARMED light is not lit: The alarm may be disarmed. Arm
the alarm by inserting a probe (straightened paper clip)
through the small ARM access opening in the faceplate,
pushing gently until the detent is felt. It may take several
pushes to trip the switch.
ALARM light is
yellow
with an intermittent horn: This
usually means low or high flow through the sensor.
Generally, with the correct flow, the ball will be between
.4 and .9, in some cases slightly higher or lower flow is
required. Increase or decrease pressure at the pressure
regulator in half turn increments until the horn silences.
Approximately one minute later, the ALARM light should
change from
yellow
to
green
.
3.2.6
A continuous alarm with
red
AIR QUALITY light
indicates that the sample air exceeds the permissible
contamination level (the digital display confirms the
contamination level), or the instrument requires a
calibration test. Refer to Section 4.0.
DO NOT use the respirator during the warm-up
period. Alarms are disabled during the warm-up
and do not warn against toxic gases.
3.3
Operating Mode
3.3.1
Following the warm-up period, with the toggle
positioned to RUN, and the sample air flowing through
the unit, the monitor is in full operating mode.
3.3.2
Before donning the respirator, make sure the
monitor is in the operating mode; all three alarm-lights
must be lit
green
, with no audible alarm.
Do not use compressed air monitored by this
instrument for breathing without checking to
make sure the instrument is in full operating
mode, and all the annunciator lights are
illuminated
green
. Failure to heed this warning
can cause death from the inhalation of carbon
monoxide.
3.4
Shutdown
3.4.1
If the instrument is in a facility that has 24-hour
compressed air and electrical power, there is no need to
shut off the monitor. If the compressed air system is
shutdown, the electrical power must also be turned off,
by unplugging the power cord, or disengaging power if
the monitor is permanently wired.
If the compressed-air source is shut down
without shutting off electrical power, the
monitor will go into low-flow alarm, sounding
an intermittent alarm and displaying a
yellow
ALARM light.

CALIBRATION TEST and CALIBRATION
Note: Thoroughly review and understand the calibration
test and calibration process before testing or calibrating
the instrument..
The following calibration instructions are
written for 10 PPM of CO Test Gas. To avoid
confusion, do not test or calibrate the
instrument with any concentration of CO test
gas. Using other concentrations, while
following the calibrating instructions, will place
the monitor out of calibration, and may fail to
alert the user of toxic gases. Breathing toxic
gases can cause death.
The following materials are required for tests and
calibration:
10 PPM test gas ............................. Stock No. 22865
Impurity-free test gas .................... Stock No. 11132
(when required, see Section 4.8)
Calibration connector ..................... Stock No. 23011
Small probe such as a straightened paper clip
(only when calibration is required)
4.1
Difference Between Calibration Test and the
Calibration Process
4.1.1
It is important to understand the difference
between calibration testing and the calibration process.
