Using the White Calibration Plate

CAUTION
Do not perform measurement with the specimen measuring port directed
towards your face. Doing so may cause damage to your eyes .
Be careful around openings in the CF-300. Failure to do so may
result in fingers being trapped causing injury.
c Attach the target mask that is to be used in measurements to the instrument before performing calibration.
Procedure
1
. Remove the cap from the white calibration
plate.
2
. <For contact measurements>
Press the white calibration plate flush against
the instrument with your hand so that it covers
the measurement side of the target mask.
<For noncontact measurements>
Attach the white calibration adapter over the
target mask, then fit the white calibration
plate into to the specimen measuring port of
the adapter with the white side of the white
calibration plate facing inward (towards the
CF-300) and press it into the hole with your
hand.
Memo • Do not forget to attach the white
calibration adapter.
• Be careful not to move the white calibration plate
when calibrating the instrument's white sensitivity.

Notes on Use of White Calibration Plate

Memo • When performing white calibration, the white calibration data for the white calibration plate being used is required.
The white calibration data for the white calibration plate included with the instrument is stored in the instrument's
memory at the time of shipment.
c The white calibration plate may become discolored if left exposed to light. Therefore,
when not in use, make sure that the lid is closed to prevent exposure to light.
c Take care not to scratch, touch, or make the white calibration plate surface dirty with such as fingerprints.
c If the white calibration plate gets dirty, wipe it with a soft, clean, dry cloth.
c If dirt is difficult to remove, dampen a cloth with commercially available lens cleaning liquid and wipe
the white calibration plate. Then wipe off the liquid with a cloth dampened with water, and leave the plate
to dry.Should the white calibration plate get so dirty that it cannot be cleaned, replace the plate with a
new one. If the White Calibration Plate is changed, reset the white calibration data to the new plate's.

Updating White Calibration Data

c You may the "Data Setting Tool software" stored on the CD-ROM accompanying White Calibration Plate
CM-A24 or the optional Color Data Software SpectraMagic DX to set the white calibration data.
