2. Highlight LS Cotton in the Calibration Type window.
3. You are instructed to perform Test 1 of 12 for short cotton.
4. To begin the measurement process, place approximately 10 grams
of fiber in the sampler drum(s).
5. Make sure your hands are clear of the doors that cover the sampler
drum(s) and press the START button on the top of the
Length/Strength cabinet.
CAUTION:
Make sure your hands, jewelry, clothing, and any other
loose items are clear of the doors that cover the sampler
drums before you press the start button that begins the
cotton sample preparation and measurement process.
6. The doors are closed automatically and the FIBROSAMPLER
prepares the comb(s) from the material in the drum(s) (one comb is
prepared from the material in each drum).
7. The comb(s) slide along the comb track until the first one is
positioned in front of the brusher.
8. As soon as the comb is in place, the brusher automatically removes
loose fibers from the beard while simultaneously cleaning and
aligning the remaining fibers.
9. It is then moved along the comb track to the lens and jaw system
where the tests for length, uniformity, strength, and elongation are
performed.
10. While the first cotton sample is being measured, the second cotton
sample is being brushed (for M1000).
11. After the measurements for the first cotton sample are complete, it
continues to move down the comb track until the second cotton
sample is in the proper position for measurement (for M1000).
12. After the measurements are complete for both cotton samples (or
for the first M700 cotton sample) the comb(s) slide back down the
comb track and are positioned in front of the sampler drum.
