1.2 Operational Overview
Pressing the I/O button turns the analyzer ON. Note that there is a warm-
up period of 60 seconds before the unit can be used for testing.
After completion of the warm-up period, choose a fuel code that corre-
sponds to the fuel being burned by the appliance being tested, and then
press the ENTER 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 displayed on the analyzer’s LCD, and are chosen
for display by pressing the Increment () and Decrement () buttons.
Pressing the HOLD button during a test will freeze all measured and calculat-
ed values at their current levels. Pressing the ENTER button resumes testing.
Pressing the HOLD button twice during a test will display the Print/
Memory Menu Screen. Using the and ENTER buttons, the operator can
choose to print the current readings, save the current readings in memory,
recall and view saved readings from memory, clear all the memory, or print
all saved readings.
A backlight enables an operator to read the display in dimly-lit areas.
Pressing the LIGHT button turns the backlight ON and OFF. The backlight
will automatically turn OFF after 10 minutes of keyboard inactivity.
A power saver function will shut the analyzer OFF after 20 minutes of
keyboard inactivity. The power saver function is disabled if the detected O
2
value is less than 17.9%, or for analyzers with a CO sensor the CO value is
more than 50 ppm.
Press the I/O button to turn the analyzer OFF. Note that there is a 5 sec-
ond delay before the analyzer actually turns OFF, during which time the
unit can be kept ON by pressing the ENTER button. For analyzers that
contain a CO sensor, there is a CO purge feature that keeps the analyzer’s
pump running until the measured CO level drops below 50 ppm.
