4.3 Operating 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.

• If the CO channel (Model 125E only) is set up for Auto Zero (refer to

Section 3.5.3), ensure that the analyzer is sampling fresh air when

turned ON. Pulling a flue-gas sample through the analyzer during its

warm-up period will not damage the analyzer, but it will result in in-

correct CO readings. Also note that a CO sensor error will occur if the

detected CO level is above 50 ppm during warm-up.

• When measuring flue-gas, note that flue-gas condensate is acidic and

very corrosive. It is important not to allow the analyzer’s internal com-

ponents to become soaked in 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. Refer to Section 5.8.

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

keep the trap in a vertical position. This will maximize the effective-

ness of the trap and keep liquid condensate from being drawn directly

into the analyzer.

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

before it becomes full. Refer to Section 5.8.

• It is recommended that the analyzer be purged after taking a flue-gas

measurement before turning it OFF. Once the probe is removed from

the stack, disconnect the hose assembly from the bottom of the analyz-

er and let the pump run for 10 minutes or so to completely remove any

remaining flue gases and dry any condensate from inside the sensor

chamber.

• 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 to ensure its accuracy.
