measurement screen will display. If this is the first time you
have used the instrument, you will see "no batches".

instrument on the batch sample and press the measurement
button.
After the batch has been measured, the output screen will be
displayed.
This display screen includes the absolute colorimetric data for
the standard and batch, and the color difference data for the
samples. When the gloss feature is enabled, the gloss
information is also displayed.

current date and time. The batch naming method can be
edited in the Options screen.

sample and press the measurement button. As long as you
remain in Batch Mode, each measurement you make will
