With gentle, uniform pressure, wipe the mirror from one edge to the
other with the cleaning cloth only once and only in one direction to
remove the contamination. Discard the cloth.

Repeat with a clean sheet of lens cleaning cloth to remove the streak
left by the first wipe. Repeat, if necessary, until there is no visible
contamination on the mirror.
16.
Carefully replace the mirror assembly onto the cell in the same
orientation as previously marked making sure the o-ring is properly
seated.

Excessive Sampling Gas Temperatures and
Pressures
The embedded software is designed to produce accurate measurements only
within the allowable cell operating range (see Table B–1 on page B–1 or
Table B–2 on page B–2). Pressures and temperatures outside these ranges will
trigger a
P/T Fail
fault.
Electrical Noise
High levels of electrical noise can interfere with laser operation and cause it to
become unstable. Always connect the analyzer to a properly grounded power
source.
Peak Tracking Reset Procedure
The analyzer’s software is equipped with a peak tracking function that keeps
the laser scan centered on the absorption peak. Under some circumstances,
the peak tracking function can get lost and lock onto the wrong peak. If the
difference between
PkDf
and
PkD1
is more than 4, or
Track Fail
is displayed,
the peak tracking function should be reset.
Never rub an optical surface, especially with dry tissues, as this
can mar or scratch the coated surface.
If the pressure, temperature, or any other readings on the LCD
appear suspect, they should be checked against the specifications
(see Table B–1 on page B–1 or Table B–2 on page B–2).
