Page 18: Software Version 4.0 Features
Instruction Manual Software Version 4.0 Features The HVI 900 system’s version 4.0 software uses a pop-up menu structure. This allows you to select the procedures to be performed from options displayed on the screen. Once a selection has been entered, the screen reflects the choice and displays the next menu or procedure level.
Page 19: Keyboard Commands
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.

Page 27: Chapter 2 Installation
USTER® Instruction Manual Chapter 2 Installation The HVI 900 System is shipped in three separate crates containing the module cabinets, peripherals, and some of the internal parts of the system. Any loss or damage should be immediately reported to the carrier.
Page 28: Electrical Power Requirements
Electrical Power Requirements All the system components are plugged into the power strips in the back of each of the cabinets. The Version 3 HVI 900 instrument operates on 230 volts (50 to 60 Hz) and requires a separate dedicated 15-amp circuit breaker at the facility’s electrical load center.
Page 29: Compressed Air
HVI 900 USTER® Instruction Manual The instrument must be operated in a controlled environment in the range of 20°C ±2°C (65°F to 72°F). The relative humidity should be 65%, ±2%. For consistent results, fiber samples should be conditioned in the laboratory environment.
Page 30: Floor Space Requirements
HVI 900 USTER® Instruction Manual Floor Space Requirements The 900 SA is always installed in a straight-line configuration. The Length/Strength cabinet physically occupies a space of 137 cm (54 inches) long by 80 cm (31.5 inches) deep. The working surface is 98 cm (38.5 inches) from the floor.
Page 31: Connections
Connect the bar code reader to the cable labeled COM2 (located in the Micronaire cabinet). The HVI 900 system is now ready for use. Allow the system to warm up for at least four (4) hours before performing calibrations for the first time.
Page 32 HVI 900 USTER® Instruction Manual Most cotton standards organizations recommend that the temperature be in the range of 20°C ±2°C (65°F to 72°F) for a testing cotton environment. The relative humidity should be 65%, ±2%. It is suggested that fiber samples be conditioned in the laboratory environment for consistent testing results.

Page 66: Uster® Sci Regression Coefficients
4.18 Uster® SCI Regression Coefficients Uster® Spinning Consistency Index (SCI) is a calculated value based on multiple regression analyses that compare fiber properties to yarn properties. Each equation takes into account all HVI properties, and calculates one value to be used on each test sample. The standard equation for SCI is based on the following information.
Page 67 A screen is displayed that lists the standard values recommended by Uster Technologies, Inc. and the current values used for calculating SCI. The standard values listed in the first (left) column are the values recommended by Uster Technologies.
Page 68: Csp Regression Coefficients
HVI 900 USTER® Instruction Manual The Uniformity standard value will change depending on whether ICC (ratio) or HVI (index) cotton has been selected as the Calibration Mode. The Length standard value will change depending on whether English or Metric has been selected as the Length Units measuring system. The choices are shown in parentheses beside uniformity and length.
Page 69 Instruction Manual The CSP Regression Coefficients screen displays the standard values recommended by Uster Technologies, Inc. and the current values used for calculating CSP.

Page 202: Importance Of Testing Fiber
Research conducted by Cotton Incorporated (USA) and Uster Technologies indicates the influence of HVI measured fiber properties on yarn strength. When spinning a Ne 26, one can see that length, length uniformity, strength, and micronaire predict over 75% of possible variation in yarn strength.
Page 203: Applications Of Hvi Results For Spinning Mills
HVI 900 USTER® Instruction Manual Applications of HVI Results for Spinning Mills The speed of the HVI instrument allows every bale of cotton to be tested. The challenge then becomes how to effectively use the information to improve the spinning process. All cotton has a natural variation of fiber properties.
Page 204 HVI 900 USTER® Instruction Manual The next graph shows the influence of yarn strength, as well as yarn strength CV%, on the weaving end breaks. Higher speed weaving machines need yarn that is not only stronger but also yarn that has a better yarn strength CV%.

Page 206: Influence Of Staple Length And Yarn Strength
HVI 900 USTER® Instruction Manual Influence of Staple Length and Yarn Strength Textile research further indicates that as cotton staple length increases so does the strength of the resulting yarn. Generally, longer staple cottons tend to be finer, thereby allowing a greater number of fibers per cross- section in yarn.
Page 207: Influence Of Micronaire And Yarn Strength
HVI 900 USTER® Instruction Manual Influence of Micronaire and Yarn Strength Textile research indicates that micronaire influences the amount of fibers per cross-section, thereby affecting yarn strength. Generally, lower micronaire fibers are smaller in perimeter, and thus finer, allowing more fibers per cross-section.

If the metal length standard will not slide in/out from the track easily, refer to the following instructions to raise the cabinet top and insert/remove the comb.
Page 219 HVI 900 USTER® Instruction Manual If the standard measurement is within 0.004 inches of the actual standard value, the instrument returns to the Length/Strength Calibration Menu when you press ENTER. If the value is greater than ±0.004 inches of the actual value, a Fail indication is displayed.

Calibration Status • Select the item from the S YNTHETIC IBER ALIBRATION It contains three menu options: Synthetic Fiber Standard Values, Synthetic Fiber Calibration Constants, and Synthetic Fiber Calibration Tolerances.
Page 223 HVI 900 USTER® Instruction Manual 3.5.5.1 Synthetic Fiber Standard Values The values entered on Synthetic Fiber Standard Values screen will be displayed and used as the Standard Values for Calibration. If no value is entered for Elongation, Uniformity, or Strength, that property will not be calibrated.
Page 224 HVI 900 USTER® Instruction Manual 3.5.5.2 Synthetic Fiber Calibration Constants • Change the values by using the arrow keys to highlight the item, then by pressing the ENTER key. Enter the value at the prompt, and then press ESCAPE to save the data.
Page 225 HVI 900 USTER® Instruction Manual 3.5.5.3 Synthetic Fiber Calibration Tolerances The Synthetic Fiber Calibration Tolerance values should be about 1.5 to 2.0 times the standard deviations obtained during testing. If the standard deviation for strength is 1 gram per tex, the strength tolerance should be set to 1.5.
Page 226 HVI 900 USTER® Instruction Manual 3.5.6 Fiber Calibration Once the number of tests has been established, the fiber calibration can begin. • Select the Fiber Calibration item from the S YNTHETIC IBER ALIBRATION The top of the Synthetic Fiber Calibration screen lists the current calibration values for Len 1, Len 2, Uniformity, Strength, and Elongation.
Page 227 HVI 900 USTER® Instruction Manual As long as the difference between the Average and the Standard Values are within Tolerance, the calibration will pass. • To continue, press ENTER. A printout containing individual test data, low, high, range, average, and standard values will be generated.

IBER TATUS Note: Brusher Forward, Breaker Read Rate, and Comb Read Rate are the only items that should be changed without consulting Uster Technologies. In general, the comb and breaker rates for synthetic fiber must be lower than for cotton. The lower comb rate is a result of the fact that static electrical forces are higher in Synthetic fiber than in cotton.

Page 251: Chapter 13 Fibrosampler 192
The Uster Technologies’ Fibrosampler 192 is an instrument that uses a Fibrocomb to form a sample beard of randomly selected fibers. The beard, which is held by the Fibrocomb, is placed in Uster Technologies’ Fibrograph to test for span length or the HVI Semi-Automatic to test for span length, length uniformity, and strength (tenacity).

Page 253: Theory Of Operation
HVI 900 USTER® Instruction Manual Theory of Operation Sample beard preparation is a critical step in any scientific test procedure that strives to achieve statistically valid and repeatable results. The Fibrosampler 192 selects a random sample by presenting to the Fibrocomb a series of small staggered tufts. These are created by the hole pattern in the sample plate against which the fiber is pressed.
