Note:
Allow the balance time to stabilize and make the correct
reading before removing the fiber. The system will not accept the results
until a stable reading is taken.
• When the sample weight is within range, the weight is displayed in
the WGT field on the
HVI
SPECTRUM
TESTING screen.
• Insert the weighed sample into the micronaire chamber and close the
lid. The micronaire test will begin automatically.
• The chamber lid will open once the test is completed and the sample
is ejected from the chamber.
• The micronaire value will be displayed in the box for MIC in the
Micronaire
area.
• The maturity of the cotton will be displayed in the box for MAT after
the length/strength measurement tests are complete.
Note:
Maturity Index is an optional setting.
If the Micronaire value is outside the set limits:
• Select the NEW TEST button to accept the value and proceed with
testing.
• To reject the value and perform another test sequence on the sample,
press the REJECT TEST button and then press the NEW TEST button.
• Checking the “…AND NEP” box allows you to reject NEP data as
well as other data.
Note: If an error message appears repeatedly, it could indicate an air
leakage in the micronaire chamber. In such a case, perform a
micronaire calibration check to ensure that it is accurate. If necessary,
contact an Uster Technologies’
Service technician for further support.
