USTER HVI 900 - Length;Strength Setup; Synthetic Fiber Calibration

USTER® HVI 900 Instruction Manual

3 Length/Strength Setup
Length/Strength Setup menu item is to be used by Service Technicians
only to perform the Lens to Break and Deflection Calibration, and the
Short Fiber setup.
IMPORTANT
THE LENS TO BREAK AND THE DEFLECTION CALIBRATION
MUST BE DONE PRIOR TO CALIBRATING FOR
COTTON/SYNTHETIC FIBERS. Cotton/Synthetic Fiber
calibration is invalid if the Length Standard or Lens to
Break values are modified. Contact an authorized Uster
Technologies Service Technician to perform these setup
features if necessary.
3.4 Synthetic Fiber Calibration
All fiber types must be calibrated during initial setup in the following
order: length standard, lens to break and then calibration to the various
fiber types (e.g., cotton). If these have been performed for cotton at the
time of setup, there is no need to repeat these calibrations for synthetic
fibers; the same values are used in both programs.
However, if these have not been set up during initial calibrations, do so
using the instruction that follow in this section.
The S
YNTHETIC FIBER CALIBRATION MENU is used to perform synthetic fiber
calibration. It contains the following menu options: Fiber Calibration,
Number of Tests, and Calibration Status.
Note: Micronaire cannot be calibrated for synthetic fibers. It must be
calibrated during the cotton calibration process.
