3.5.4 Number of Calibration Tests
Before performing a calibration, the number of repetitions that should be
performed per test should be established. This is done using the
Number of Calibration Tests
item on the SYNTHETIC FIBER TESTING MENU.
• Select the
Number of Tests
item using the arrow keys, then press the
ENTER key.
• Each calibration will consist of 4, 8 or 12 tests. To change the
number of tests, enter 4, 8 or 12 at the prompt, then press ENTER.
Although performing four (4) tests is an option, it is advised that at least
eight be performed, particularly if there is a great deal of variation in
the fiber or the sampling of the fiber.
