• When storing the analyzer, it’s a good idea to empty the water trap
and leave it open to further dry it out.
• Calibrate the analyzer every 6 months - 1 year to ensure its
accuracy.
4.2 Turning ON the Analyzer and Warm Up
Connect the probe and hose assembly, and make sure that the analyzer is
properly set up per Section 3.
IMPORTANT: DO NOT insert probe into stack before
turning ON the analyzer!
1. Place the probe in an area that
contains fresh air. This ensures that
the sensors will be properly zeroed
during the warm-up cycle.
2. Turn ON the analyzer by pressing
the I/O button for at least 1 second, or
until a single beep is heard. Observe
that the analyzer’s fi rmware version,
model and serial numbers are briefl y
displayed followed by the Warm Up
screen.
3. Wait for the analyzer to count down
its 60 second warm-up period; after
which, the instrument will display the
Combustion Test HOLD screen.
4. If problems were detected during
warm up, the message “ERRORS
DETECTED” is displayed along with
a list of those errors. As an example,
the screen to the right shows that the
battery is low. Refer to Section 7.3 for
a listing and possible remedy for the
errors displayed.
TIP: If the sensors in error are not
critical to the combustion test, then
press the RUN/HOLD button to
display the Combustion Test HOLD
screen and proceed with the test.
