3 Overview of Testing
Sequence
This manual has been written using Length/Strength, Micronaire, and
Color/Trash modules. On that basis, the following is a summary of the
suggested testing sequence that may be used when testing cotton fibers.
♦ Sample ID—The cursor is positioned in the ID field where the ID for
the sample should be entered using the bar code reader (if you have
purchased that option) or via the keyboard.
♦ Micronaire—Because the micronaire value is used to calculate the
length/strength values and the fineness value, it is suggested that the
Micronaire Test be completed first.
° Weigh the sample on the balance.
° Place it in the micronaire chamber and close the door.
° The test is performed and the sample ejected.
° Discard the cotton sample.
♦ Color/Trash—These tests can be performed simultaneously (if the
S
TATUS MENU selections are set to "On").
° Place a cotton sample on the Color Tray.
° Press the start buttons that are located on both sides of the Color
Tray. (If the HVI serial number ends with "UZ," it will only have
one start button located to the right of the color tray.)
° The sample is compressed to eliminate air pockets, and the
measurements are made. The Color Tray Arm returns to its resting
position and repeats the process the number of repetitions
specified by the S
TATUS MENU.
