Measuring/Editing a Color Reference

The reference function is used to enter color reference
data into the instrument using a sequence or match
method. Up to 16 references can be stored and accessed in
the instrument. Color reference values are then compared
to color measurements and the difference displayed.

To measure a reference:

1.

If not selected, press the Tab Up key

$

or Tab Down

key

@

to highlight

Reference

and press Enter key

#

.

NOTE:

Reference

will not appear in the measurement list unless

COLOR–REF01

is selected as the active color mode. Refer to Color

Measurement Mode earlier in this section.

2.

Press the Tab Up key

$

to move highlight to the

reference measurement method (

Seq

or

Match

).

•

The

Sequence

(Seq) method automatically

increments the reference location as you measure.
For example, when the highlight is on

Ref 01

, and a

measurement is taken, the data is set for reference
one and the highlight advances to

Ref 02

. This

occurs for all reference measurements taken.

•

The

Match

method is used to update an existing

reference. The measurement automatically replaces
data in the location that has the closest match (lowest

Δ

E) to the measurement.
