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
combustion process. These values are dis played on the analyzer’s LCD, and
are chosen for display by pressing the In cre ment (▲) and Dec re ment (▼)
but tons.
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 dis abled 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.
