Note: If the size of the sample beard is too large or small for the
measurement mechanisms, an error message saying "Large Sample" or
"Small Sample" will be displayed. When either of these messages
appears, simply perform another repetition.
• Make a beard using the Fibrosampler and the correct calibration
cotton. The proper technique for using the Fibrosampler is described
in Chapter 13, Fibrosampler 192-1, in this manual.
• Place the sample in the comb track of the Length/Strength console
with the beard extending toward the black brushing surface. Press
the green Length/Strength start button to initiate the test.
The brusher removes loose fibers and cleans and aligns the fibers for
measurement. After the brushing operation is completed, a mechanical
finger slides the sample into the comb holder. The sample is measured,
and the instruction statement directs you to perform Test 2 of 12 for
Short Cotton.
Note: Once the test is completed, the comb will be pushed to the far
left of the console when the next sample is tested.
• Follow the instruction statements to perform tests 2 through 12 with
the short calibration cotton. If needed, press “ESC” to exit and to
reject a sample. The LENGTH/STRENGTH CALIBRATION MENU will
reappear and the calibration procedure can be restarted.
• After every other comb is made, rotate the cotton in the
Fibrosampler.
•
If the error message “Reject—Check Sample” appears in the lower
right corner of the screen, recheck to see that the correct box of
calibration cottons is being tested (the values listed on the box and
on the screen must be identical).
•
After the last Short Cotton test, the display changes to request that
12 tests be performed on Long Cotton.
