Note: Once Lot ID is entered; it is carried over when the next bale
from the same lot is tested. When testing bales from a new lot, you
must re-enter from the HVI SPECTRUM T ESTING screen to change the
Lot ID. The Bale ID field must also be modified each time a new
sample is tested.
Note: If a bar code reader is used to enter the Bale ID, hold the bale
tag with the code facing up. Slide the tag toward the reader until the
beam is centered over the bar code on the tag. When the code has
been read, the bar code reader will beep and the beam will shut OFF.
2.5 Step 5—Perform the Micronaire Test
• Select the NEW TEST button.
The micronaire tests are performed next. Depending on the test setup
parameters, they can include the micronaire test and the maturity index.
The weight of the fiber is always taken.
The Micronaire measurement is used to calculate the
values for Strength. Although the Micronaire
measurement does not have to be completed before the
Length/Strength and Color/Trash tests are run, it must
be complete before the test results can be displayed on
the HVI SPECTRUM Testing screen.
• Prior to placing the fiber on the balance, make sure the panel
reads "0.00”. It may be necessary to tare the balance to get rid
of any drift from zero that might occur. To do this, press the bar on
the front of the balance.
Note: The newer style balance has a T ARE button instead of a bar.
• Place the fiber on the balance. The sample must weigh between 8.5
and 11.5 grams for the micronaire test to be performed. Add or
subtract fiber until the sample weight is within the acceptable limits.
• The sample weight is displayed on the balance display.
