4.1Operating Tips

•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.

Caution: Although the analyzer itself is not damaged by an ex- tremely cold environment, the electrochemical sensors may be damaged. The O2 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.

4.2Analyzer Power On & Warm Up

1.Connect the probe and make sure that the analyzer is properly set up per Section 3.

IMPORTANT! 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

PWR button for at least 1 second, or until
a single beep is heard. Observe that the
analyzer's firmware version, model and se-	V1.00
	24-8250
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.

4.3 Fuel Selection

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 MENU (F2) button. If necessary, press ESC until MENU appears above F2

2.Use the ▲▼ buttons to select FUEL. Press ENTER to display the Fuel Selection screen.

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