Port Inserts
Port inserts with various-sized openings may be purchased and placed at the
reflectance port to change the area of view. Remove the standard port insert by
pulling it out of the port insert retainer. Replace it with the special port insert. Make
sure that the flat portion of the insert is facing outward with the beveled portion
toward the interior of the sensor. Then standardize the instrument. Any change in
port size must be followed by standardization on both the Black Glass and the
calibrated White Tile.

and airborne particles. Remove the standard port insert by pulling it out of the port
insert retainer. Replace it with the glass port insert. Make sure that the flat portion
of the insert is facing outward with the beveled portion toward the interior of the

Diagnostics without the glass cover. Difference measurements using a glass cover
will be more accurate than absolute measurements.
