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 dam-
age the analyzer; however, bringing a cold analyzer into a warm humid
environment may cause condensate to form inside the case.
• If the CO channel (Fyrite Tech 60) is set up for Auto Zero (refer to Sec-
tion 3.5.3), ensure that the analyzer is sampling fresh air when turned
ON. Pulling a
fl
ue-gas sample through the analyzer during its warm-up
period will not damage the analyzer, but it will result in incorrect CO
readings. Also note that a CO sensor error will occur if the detected CO
level is above 50 ppm during warm-up.
• For analyzers that are used to measure
fl
ue-gas, note that
fl
ue-gas
condensate is acidic and very corrosive. It is important not to allow the
analyzer's internal components to become soaked in condensate for long
periods of time.
• Before each use, inspect the
fi
lter element of the water trap /
fi
lter assem-
bly. Replace the
fi
lter if it looks dirty.
• When sampling
fl
ue-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 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 5.6.
• It is recommended that the analyzer be purged after taking a
fl
ue-gas
measurement before turning it OFF. Once the probe is removed from the
stack, disconnect the hose assembly from the bottom of the analyzer and
let the pump run for 10 minutes or so to completely remove any remain-
ing
fl
ue 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.
