6-2. Insertion Into the Main Unit
Insert the sample case into the sample case slot on the
main unit until it cannot be inserted any further.
[Caution] Make sure the sample case is facing the correct
direction.
6-3. Measurement
Once the sample case has been inserted into the main unit,
the number of times measured and the whiteness value are
displayed on the display.
■ Average Value
You can also display the average value of two to nine
measurements. After performing between two to nine
measurements, press the key to view the average
value and the number of times measured. Once the
average value is displayed, all values up to that point are
cleared and the next measurement is treated as the first
measurement of a new set.
The number of measurements is displayed after each
measurement is completed.
However, the number of measurements is reset to one in the
following cases.
(1) When the key is pressed.
(2) When the number of measurements exceeds nine.
6-4. Sensitivity Calibration
After performing measurements for a long period of time,
the sensitivity of the device may need to be re-calibrated.
Therefore, you must check the sensitivity of the device from
time to time.
To check the sensitivity, insert the whiteness standard plate into
the main unit and measure the value of the whiteness standard
plate. If this measurement value is not equal to the number on
the whiteness standard plate, the sensitivity needs to be re-
calibrated. Press the key with the whiteness standard plate
still inserted to automatically calibrate the sensitivity.
You can also press the key to calibrate the sensitivity
when "STD" is displayed in the upper-left corner of the display.
