Instrument Warranty
All USTER® instruments are covered by a limited warranty, conditions of which may vary according to local laws.
We are required by current U.S. regulations to call this a "Limited Warranty" because there are ways a user might
cause damage to this equipment that are completely beyond our control. Uster Technologies, Inc. assumes no
responsibility for the customer's process, facilities, or personnel. The customer is liable for damage of this sort. Failure
to supply specified electrical and air requirements will void the warranty.
The warranty period is 12 months from the date the instrument is installed at the purchaser’s site, or 18 months from the
date the instrument is shipped from the Uster Technologies, Inc. factory.
Further, Uster Technologies, Inc. will replace externally undamaged glass electrodes, measuring cells, and electron
tubes within 6 months of delivery if test results reveal manufacturing faults or insufficient life.
Upon written request of the purchaser within the warranty period, we will repair or replace (at our discretion) any
instrument or part that fails in normal use as a result of improper design, faulty materials, or faulty workmanship.
Replaced parts shall become the property of Uster Technologies, Inc.
In the event that the defective part/instrument must be returned to the factory for repair, transport both ways shall be at
the cost and risk of the purchaser. Also the costs of dismantling and re-erection of the defective part are to be carried
by the purchaser. If, for any reason beyond our control, such part cannot be repaired or replaced at our factory all
additional costs resulting therefrom shall be borne by the purchaser.
The purchaser shall not be entitled to claim any further indemnity for deficiencies in the goods delivered, in particular
for damages or for cancellation of the contract.
All contractual obligations of the vendor expire unless the purchaser advises Uster Technologies, Inc. of any claims
arising under the guarantee in writing before expiry of the warranty period.
Excluded from the warranty are defects and losses resulting from improper storage, natural wear, improper
maintenance, failure to observe the operating instructions, excessive loading, the user of unsuitable media, the influence
of chemical or electrolytic action, unsatisfactory building or erection and commissioning work not undertaken by Uster
Technologies, Inc., or other reasons beyond our control.
The vendor’s liability shall cease if the purchaser or a third party undertakes changes or repairs to the goods without the
written consent of Uster Technologies, Inc., or if such goods are resold by the purchaser to a third party without an
agreement from the Uster Technologies, Inc.
For materials or goods supplied by third parties, the Uster accepts liability only to the extent of the guarantees provided
by such third parties.

USTER® HVI 900 Instruction Manual
Uster Technologies, Inc. Chapter 1
Version 4.0 (1.99) Introduction - Page 1-1
Chapter 1 Introduction
The USTER® HVI 900™Instrument measures the seven physical
characteristics defined by the United States Department of Agriculture
(USDA) in its cotton marketing system. It measures fiber length, strength,
length uniformity, elongation, micronaire, color, and trash. All of these
properties are important in fiber research, in the development of
improved fiber blends, and in verifying that purchased fiber meets
specifications.
The HVI 900 fiber test system offers precise and reliable automated
operation with computer controlled calibration and diagnostics. All
functions are controlled by dedicated microprocessors to simplify
operation and to provide flexibility in testing parameters. The computer
system has both a 3.5-inch and a hard disk drive.
3HVI 900 Equipment
The following features are available on the HVI 900 unit:
♦VGA color monitor
♦Keyboard
♦IBM-compatible computer chassis
♦Hard disk drive loaded with the necessary interface, operations,
calculation, and reporting packages (a licensed version of MS-DOS
is also provided)
♦3.5-inch floppy drive
♦486 CPU type, 4 meg of memory
♦Balance

Version 4.0 (1.99) Introduction - Page 1-3
5HVI 900 System Modules
The HVI 900 system is housed in two floor-standing cabinets: the larger
cabinet contains the Length/Strength Module and the smaller cabinet
contains the Micronaire and Color/Trash Modules. Included with the
system are an alphanumeric keyboard, a monitor and a balance. The
monitor displays the menu selections, operating instructions and test
results. As tests are completed for each sample, the results can be
transmitted to a printer and/or an external computer system, if
available. The HVI 900 system consists of modules that can be
combined in a variety of ways. Your system may include any or all of
the following components: the Length/Strength Module, the Micronaire
Module and the Color/Trash Module.
5.4 Length/Strength Module
The Length/Strength Module optically determines fiber lengths and
associated uniformities. The length, known as the “elongation,” is
calculated by averaging the length of distance the fibers will extend
before breaking. The Strength is determined by measuring the force
that is required to break a sample of a known mass.
The Length/Strength Module of the HVI 900 consists of a brushing
mechanism, an optical system for measuring length and uniformity, and
a clamping jaw system for measuring strength and elongation. It is
operated by placing a sample prepared using the Fibrosampler 192 in
the comb track of the Fibrograph Plus where it is automatically brushed
and moved into position for testing.
The brushing and measurement mechanisms are located on the top of
the left cabinet. A lint/waste box and blower system is located
underneath the left cabinet.
Version 3 (automatic) instruments operate differently than previous HIV
900 Semi-Automatic systems as a result of the following features being
added to the instrument.

USTER® HVI 900 Instruction Manual
Uster Technologies, Inc. Chapter 1
Version 4.0 (1.99) Introduction - Page 1-4
♦The comb track is now enclosed within the Length/Strength cover.
To access it, lift the door located on top of the brusher and place the
fibrocomb in the track. The Length/Strength start button is then
pressed to initiate the measuring process, or it can be automatically
prompted using the software.
♦The main power and blower switches are located on the
Length/Strength Module plexiglass cover.
♦The vacuum box has been replaced with a lint/waste box and
blower system. The lint/waste box is located behind the left door of
the Length/Strength Module cabinet. The blower can be turned off
when not required for measurements.
♦Two buttons, located on both sides of the Color/Trash mechanism,
must be pressed simultaneously to initiate the Color/Trash Test.
5.5 Micronaire Module
Micronaire is measured by relating air flow resistance to the specific
surface of fibers. An air stream is passed through a known mass of
fiber confined in a chamber of fixed volume. The pressure differential
across the chamber is then related to the specific surface of the fiber to
determine the micronaire value for cotton.
Before a sample is placed in the micronaire chamber, it must be
weighed. A precision electronic balance is provided to weigh the
sample and is protected by an acrylic guard (the optional bar code
reader can be attached to it). The testing chamber for micronaire
measurements is located directly below the electronic balance.

USTER® HVI 900 Instruction Manual
Uster Technologies, Inc. Chapter 1
Version 4.0 (1.99) Introduction - Page 1-5
5.6 Color/Trash Modules
The Color/Trash instrument for measuring cotton color (reflectiveness
and yellowness) and trash is located in the smaller cabinet that also
houses the Micronaire Module. The color/trash tray is mounted on the
tabletop. A pneumatic-powered automatic pressure plate that applies a
consistent amount of pressure during testing is located directly above the
tray.
Color and trash are measured by placing a sample on top of the tray
and by pressing the start button(s) (mounted flush with the tabletop on
either one or both sides of the color/trash tray). This will cause the
pressure plate to descend to the test tray.
The HVI 900 system uses two lamps to measure a sample during testing.
The two color components of cotton—reflectiveness and yellowness—
are measured when the light reflected passes through the filters and is
deflected by photo diodes. This reflectiveness is expressed as a percent
reflectance (%Rd).
The yellowness is expressed in Hunter's scale (+b) values. These values
are converted into the equivalent USDA color grade codes that are
based on the universal standards for grading American Upland and/or
Pima cottons.
The Trash Module is an automated video image processor that measures
the amount of visible leaf or trash in a sample of cotton. The digitized
image produces results for three measurements:
♦Trash area—the percent of the sample viewing area
occupied by trash.
♦Trash count—an indication of the number of trash
particles •0.01 inch in diameter or larger.
♦Trash code or leaf—a code value related to the trash
area (10 * trash area, example: area = 0.37%, leaf = 04).

computer. An entry can be erased any time before pressing this key
and corrected using the backspace key.
If the keyboard does not respond to input or if the system halts in mid-
operation, reset the system (refer to Resetting the HVI 900 System in
Chapter 3). If there is still no response, turn off the main power switch
located on the front of the Length/Strength cover.

the sequence. Generally, pressing the ESCAPE key can do this.
