1.3 Operational Overview
Pressing the
PWR
button turns the analyzer ON. Note that there is a
warm-up period of 60 seconds that must elapse before the analyzer can be
used.
To perform a combustion test, choose a fuel code that corresponds to the
fuel being burned by the appliance being tested (Section 4.3), and then
press the
RUN/hOlD
button to place the analyzer into its Run Mode.
Begin testing by inserting the analyzer’s probe tube into the flue-gas
stream of the appliance under test. The analyzer will monitor the flue gas
and display measured and calculated values that are relative to the com-
bustion process. These values are displayed on the analyzer’s LCD, and
are chosen for display by pressing the Increment
(

)
and Decrement
(

)
buttons. The recommended time required to achieve a stable measurement
is a minimum of 3 minutes.
Pressing the
RUN/hOlD
button during a test will freeze all measured and
calculated values at their current levels. Pressing the
RUN/hOlD
button
again resumes testing.
A backlight enables an operator to read the display in dimly-lit areas.
Pressing the
PWR
button turns the backlight ON and OFF.
An optional power saver function will shut the analyzer OFF after a set
time period of inactivity. This feature is disabled if the CO value is greater
than 50 ppm or the O
2
value is less than 16.0%.
Press the
PWR
button for at least two seconds to power the analyzer
OFF. Note that there is a 5 second delay before the analyzer actually
turns OFF, during which time the unit can be kept ON by pressing the
RUN/hOlD
button. There is a CO purge feature that keeps the analyzer’s
pump running until the measured CO level drops below 50 ppm.
