4.0 OPERATION

4.1 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.

CAUTION: Although the analyzer itself is not damaged by an

extremely cold environment, the electrochemical sensors may be

damaged. The O

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 to 1 year to assure its accuracy.

• The recommended time required to achieve a stable reading is a mini-

mum of 3 minutes.
