11. After all 24 tests have been completed; the average values and
the range of those values for the different parameters tested are
displayed in the unit message window. If a parameter’s average
value or range falls within the prescribed tolerance level, the
calibration for that parameter has “Passed” and the instrument
is properly calibrated.
12. The operator can print the results to the default printer by
selecting the PRINT button.
If there is a difference of one or more between the Standard Values
and Average measured values that exceed the Tolerance values, a
"Fail" condition will result. The "Fail" condition may be a result of
one or more of the following situations:
1. The calibration cottons may have been mixed or contaminated
with other cottons.
2. Calibration cotton moisture content may have changed since the
previous calibration.
3. The factory-set value may not be realistic when consideration is
given to the fact that cotton, even calibration cotton, is variable.
If a "Fail" condition exits, 12 more tests for short and long
cotton MUST be performed until all samples pass.
4. If there are NO changes when you are finished, select the QUIT
button.
5. Select the S
AVE AND QUIT button if changes have been made.
Note:
The
QUIT
button can also be used to interrupt the calibration
procedure.
6. Return to the L
ENGTH/STRENGTH CALIBRATION MENU by selecting the
QUIT button on the LENGTH/STRENGTH CALIBRATION DIALOG BOX.
Note: Factory Calibration screens are intended for certified Uster
