2 Testing Sequence Quick
Reference
The fiber testing sequence can be summarized as follows:
1. Sample Identification—The Lot ID and Bale ID for the sample are
entered using the keyboard. If you have purchased the optional bar
code reader, enter the Lot ID using the keyboard and enter Bale ID
using the bar code reader.
2. Micronaire—The Micronaire value is used to calculate the
corrected strength value. Therefore, it is necessary that the
Micronaire test be completed following the steps below. It must also
be completed before performing the Length/Strength
test.
a) Weigh the sample on the balance. Make sure that it weighs
between 8.5 and 11.5 grams.
b) Place the sample in the Micronaire chamber and close the door.
c) The Micronaire test is performed and the sample is ejected.
3. Length/Strength and Color/Trash (optional)—These tests
are performed simultaneously using two sample pieces from the
bale.
IMPORTANT:
It is necessary to TURN ON the Vacuum Blower BEFORE
initiating Length/Strength Testing. If the blower is off,
testing will fail.
a) Place one sample under the Length/Strength arm and the other
sample under the Color/Trash arm.
