opaque cover. Measure the sample at the sample port through the glass bottom of the sample cup with
the instrument in the port-up orientation.
Orange Juice Tube Holder (45°/0° instruments only)
This holder is designed to allow the viewing of a 1-inch glass test tube
of orange juice by the instrument through a viewed area equivalent to
that of the optional 0.75-inch port plate. The orange juice tube holder
option includes a special mounted black glass for standardization and
is recommended for use along with the Sample Clamp/Port-Forward
Stand.
To install the orange juice holder, first install the instrument onto the
sample clamp/port-forward stand as described earlier in this chapter.
Then, remove the regular port plate from the instrument port and
replace it with the tube holder port plate. Orient the port plate so that
the larger opening in the tube holder portion is facing upward. Insert
the alignment pin on the tube holder into the small alignment hole at
the top of the instrument port. When the pin is properly installed into
the hole, the tube holder should be held firmly in the upright position
at the instrument port and should not be allowed to rotate.
Then, standardize the instrument with the normal 0.75-inch port plate
in place. Replace the 0.75-inch port plate with the orange juice tube holder port plate. To use the
orange juice tube holder, fill the 1-inch glass tube with orange juice and insert the tube into the tube
holder from the top.
Citrus Option (45°/0° instruments only)
This option provides three additional indices that may be calculated and displayed in Universal’s color
data displays, Citrus Red, Citrus Yellow, and Citrus Number. Install the indices after installation of
Universal by copying the CMRINDEX.CDX file contained on the option diskette into your Universal
installation directory (C:\UNIVERSE by default). The citrus scales will then be available for use
through Universal whenever the ColorFlex is the active instrument.
