Cleaning Each Part
This section explains how to clean the White Calibration Plate, Target Mask and inside of the integrating
sphere.
White Calibration Plate
Gently wipe off dirt with a soft dry cloth. If dirt is difficult to remove, dampen a cloth with commercially
available lens cleaning liquid and wipe. Then remove the liquid with a cloth dampened with water, and
leave it to dry.
Note
Take care not to scratch the White Calibration Plate.
Target Mask
Use a blower to remove dirt and dust from the Target Masks.
Note
Do not touch the inner surface of the Target Masks with your fingers or wipe them with a cloth. If the Target
Masks are so dirty that dirt cannot be removed with a blower, contact the nearest KONICA MINOLTA SENSING-
authorized service facility.
