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.
