8. Replace parts in the Measuring Cell:
It is critical to reassemble the Reflector Block in the exact orientation
as it was assembled at the factory.
If the Cell Windows (or Window/Mirror Combination) are found to
be scratched, cracked, or chipped, replace them during reassembly. Do
not operate the analyzer with faulty parts.
a. Standard Range
Hold the Measuring Cell vertically with the Reflector Block end
up and install (2) new o-rings (P/N 100-2009), the Window (P/N
300-0281), and the Window Holder.
Orient the Reflector Block with its “peak line” at 90° to a line
through the fittings and place it on the Measuring Cell. Ensure the
Window does not slide out of position when the Reflector Block is
placed against the Measuring Cell.
Secure the Reflector Block to the Measuring Cell with (3) M4 x 35
screws. Tighten the screws evenly.
Low Range
Install (1) new o-ring (P/N 300-9060) in the end of the Measuring
Cell that connects to the Window Holder. Install (1) new o-ring
(P/N 300 9060) in the Window Holder. Place the Window (P/N
300-0281) in the Window Holder. Secure the Window Mounting
Plate to the Window Holder with (3) M3 x 10 screws.
Hold the Measuring Cell vertically with the Reflector Block end
up. Connect the Reflector Block and Window Holder to the Mea-
suring Cell using (3) M4 x 35 screws.
b. Standard Range
Invert the Measuring Cell and install (1) new o-ring (P/N 100-2009)
and the Window (P/N 300-0281).
Low Range
Invert the Measuring Cell and install (1) new o-ring (P/N 300-9060)
and the Window/Mirror Combination (P/N 300-6288), oriented
with the Mirror side away from the Measuring Cell. Install (1) new
o-ring (P/N 300-9060). Orient the Aperture Plate with the Coun-
tersink Hole aligned with the Sample fitting. Secure the Aperture
Plate to the Measuring Cell with (3) M4 x 8 screws. Tighten the
screws evenly.
