• The test is automatically performed, the lid opens, and the sample is
ejected from the chamber. The screen displays the mass for the
sample.
• Weigh the sample of high-micronaire cotton, and place it in the
chamber.
The test is automatically performed, the lid opens, and the sample is
ejected from the chamber. The screen displays the mass for the sample.
After both samples are tested, the MICRONAIRE CALIBRATION MENU will
reappear if the samples "Passed." If the calibration was not successful,
an error message will display indicating that the sample is out of
tolerance.
If necessary, the micronaire calibration process may be interrupted at
any time by pressing the ESCAPE key. The MICRONAIRE CALIBRATION
MENU will reappear.
Attention: The balance is extremely sensitive to air
currents, vibrations, etc. To ensure accuracy, prevent
any ventilation fans from blowing directly on the
balance. Also, to ensure accurate sample weights, make
sure the sample does not touch the sides of the balance’s
enclosure or hang over the balance pan.
After this initial calibration, use Micronaire Module Testing to check
calibration each day.
