PRODUCT SETUP, (TAB) PAGE 1: DISPLAY MODE
The available data display modes are ABSOLUTE and DIFFERENCE . ABSOLUTE provides
values as measured by the sensor. These values are relative to the standard white tile
supplied with the system, which in turn is traceable to measurements made by N.I.S.T.
of similar material.
DIFFERENCE provides values calculated based on the difference
between a product standard’s values and the product sample’s values.
PRODUCT SETUP, (TAB) PAGE 1: ILLUMINANT/OBSERVER
Choose the ILLUMINANT and OBSERVER that you would like to use when displaying

PRODUCT SETUP, (TAB) PAGE 2: PRODUCT STANDARD VALUES
Select the PAGE 2 TAB to enter product target values for the color scale selected.
Choose AD HOC when you wish to use the first measurement value as the standard.
Choose NUMERIC when an actual product specimen does not exist for measurement,
but the target color values are known from previous measurements.
Choose PHYSICAL when an actual product specimen is available that represents the
target color to which samples will be compared on a regular basis. A physical standard is
measured and stored in the product setup for as long as desired.
