When an analyzer is brought in from a cold vehicle, let it warm up 

slowly to minimize condensation.  Temperatures below freezing will 

not damage the analyzer; however, bringing a cold analyzer into a 

warm, humid environment may cause condensate to form inside the 

case.

: Although the analyzer itself is not damaged by an ex-

tremely cold environment, the electrochemical sensors may be 

damaged.  The O

2  

sensor's electrolyte will freeze at approximately 

-20 °F and the CO sensor's at approximately -90 °F.  If the analyzer 

is exposed to an extremely cold condition, it is strongly suggested 

that the sensor housings be examined for hairline cracks. Be aware 

that a leaking sensor can cause chemical burns to the skin and 

possibly damage the PCB assemblies.

Ensure that the analyzer is sampling fresh air when turned ON.  Pulling 

a stack-gas sample through the analyzer during its warm-up period will 

not damage the analyzer, but it will result in incorrect sensor readings, 

and may result in sensor error messages appearing after the warm-up 

cycle completes.

Note that flue-gas condensate is acidic and very corrosive.  It is important 

not to allow the analyzer's internal components to come in contact with 

condensate for long periods of time.

Before each use, inspect the filter element of the water-trap / filter as-

sembly.  Replace the filter if it looks dirty.  

When sampling flue-gas, keep the analyzer above the water-trap, and keep 

the trap in a vertical position.  This will maximize the effectiveness of the 

trap and keep liquid from being drawn directly into the analyzer.

When liquid condensate is seen inside the water trap, empty the trap 

before it becomes full. 

When storing the analyzer, it's a good idea to empty the water trap and 

leave it open to further dry it out.

Calibrate the analyzer every 6 months - 1 year to assure its accuracy.

1.  Connect the probe and make sure that the analyzer is properly set 

up per Sec tion 3.

 DO NOT insert probe into stack before powering 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. Power ON the analyzer by pressing the 

 button for at least 1 second, or until 

a single beep is heard.  Observe that the 

analyzer's firmware version, model and se-

rial 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 in-

strument will display the Combustion Test 

HOLD screen.

If, however, any errors were detected during 

warm-up, the message "ERRORS DETECT-

ED" is displayed along with a list of those 

errors.  In this example, the O2 sensor is 

missing and the T-Stack thermocouple is not 

connected.  Refer to Section 6.8 for a listing 

and possible remedy for the errors displayed.

The top line of Combustion Test HOLD screen shows the fuel currently 

selected.  If necessary, change the fuel as follows:

1. Display the MAIN MENU by pressing the 

 button.  If necessary, press ESC 

until MENU appears above F2

2. Use the ▲▼ buttons to select FUEL.  Press 

 to display the Fuel Selection screen.

3. Use the ▲▼ buttons to select the desired fuel.
