Selecting Color Data Parameters
Colorimetric data can be viewed under varying illuminant
observer conditions, and color space/indices. The color data
immediately changes to reflect the selected parameter.
To select a color data parameter:
1.
Use the Tab keys
$ @
to highlight the desired parameter.
2.
Press the Enter key
#
to page though the parameters.
Instrument Indicator Light
The LED located next to the display illuminates various color
conditions during instrument measurements.
•
Flashing Amber – instrument calibration is required or
measurement aborted.
•
Solid Amber – measurement is taking place.
•
Solid Green – measurement passed tolerancing
requirement in QA mode.
•
Solid Red – measurement failed tolerancing requirements
in QA mode.
Important Measurement Techniques
In order for the instrument to obtain accurate and repeatable
measurements, the bottom of the shoe must be flat on the
surface to be measured. When measuring curved items where a
flat surface is not available, a fixture should be used. A fixture
allows accurate positioning of the sample tangent to the
measurement plane. If the item to be measured is smaller than
the shoe, you may want to make a platform—at the same height
as the item—for the rest of the instrument to sit on. The
instrument can also be used with the shoe fully extended 180°
from the closed position. A measurement is then activated
using the Read key.
