Operation
4.2 Turning ON the Analyzer and Warm Up
1. Connect the probe and hose assembly, and make sure that the analyzer
is properly set up per Section 3 Initial Setup.
IMPORTANT: DO NOT insert probe into stack
before turning ON the analyzer!
2. Place the probe in an area that contains fresh
air. This ensures that the sensors will be
properly zeroed during the warm-up cycle.
3. 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
firmware version, model and serial numbers
are briefly displayed followed by the Warm Up
screen.
4. Wait for the analyzer to count down its
60 second warm-up period; after which, the
message “NO ERRORS DETECTED” along
with the oxygen sensor’s output voltage is
briefly displayed followed by the display of the
Combustion Test HOLD screen.
TIP: The O
2
value at the end of warm-up is
reported as "Good, Low or BAD". Consider
replacing the oxygen sensor when its value is
reported as "Low".
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.
