Calibrating the CP320
Calibrate the colorimeter each time you charge it or turn it on. In addition, it is a good idea to
calibrate it every hour when making a long series of measurements.
To calibrate the CP320
1 Remove the white standard from the plastic bag.
2 Verify that the white standard is clean.
3 Verify that the serial number of the white standard (located on a label on the back) is
the same as the serial number of the colorimeter (located on a label on the bottom of
the instrument).
4 Put the instrument on the white standard, seating the pins in the white standard in the
connector holes in the bottom of the instrument.
5 Press the green start button to turn on the colorimeter.
6 Press the MENU function key. The word CALIBRATION appears in the LCD display
with a menu choice symbol (>) to the left of it.
7 Press the ENTER function key. At the prompt FOR CALIBRATION PRESS ENTER,
Press the ENTER function key again. The colorimeter is now calibrated and ready for
use, and the LCD window returns to the previous operational display.
Using the CP320
General use of the CP320 comprises the following tasks:
♦ Taking samples
♦ Using the color-matching mode function keys
♦ Using the menu mode function keys
♦ Menu options
Taking samples with the CP320
You can take samples with the colorimeter using it as a portable or tethered device. The
operation in either case is the same.
To take samples with the CP320
1 Put the measuring tube on the color source surface and hold it firmly on the surface.
2 Press and release the green start button. The LCD displays the sample as shown in the
following example.
#1 M1 dE= 4.5
GCS-010/GCT-614
#1 indicates sample #1, M1 is the closest color match, and dE is the Delta E (the
numeric difference between the color sample and the matching color in the chosen
palette). The second line is the name of the nearest color match in the chosen palette. In
