Note for measurement
Perform measurements on a flat surface.
Glossinesses cannot be obtained with the following surfaces.
• Uneven surface
• Bent or distorted surface
• Scratched surface
• Curved surface
Remove the USB cable for measurement.
Performing measurement with the USB cable connected may
cause measurement values to be unstable.
Bring the entire measurement area into close contact with
the measurement target surface.
The measurement dimension (dimension where the light from
light source hits the measurement area) is elliptical in shape (6
12 mm) at the center of the measurement area. If the entire
measurement area is not kept in close contact with the
measurement target surface, a correct measurement value
may not be obtained due to the influence of ambient light (refer
to page 52).
This product guarantees the performance of glossinesses
from 0.0 to 100.0.
If a measurement value is outside the guaranteed range, the
following are displayed.
