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 condensation 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 O
2
sensor’s electrolyte will freeze at approximately
-25 °C and the CO sensor’s at approximately -70 °C. 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, 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 measurement is a
minimum of 3 minutes.
