♦ Length/Strength—These tests should be conducted after the color,
trash, and micronaire tests are completed. This will allow the
Micronaire and Color/Trash operator to begin testing the next
sample.
° The Length/Strength operator places the first sample in the Fibro-
sampler 192 to prepare a sample beard in the Fibrocomb
(comb).
° The comb with the sample beard is then placed in the comb track
for brushing.
° A mechanical finger moves the comb into position for measuring
length, strength, and elongation.
° The beard can be discarded from the Fibrocomb and the next
sample prepared.
Once all samples have been taken, the test results displayed on the
screen are averaged. (The number of samples to be tested is
determined by the number entered using the STATUS MENU, which is
discussed in Chapter 4.) If, according to the selections made on the
STATUS MENU, the results are to be sent to a printer and/or external
computer, they are then transmitted.
