2. Installing the 4-Point Expansion Board CA-B04

Installing the optional 4-point expansion board CA-B04 in the instrument allows simultaneous measurement of the

colors or flicker at up to 5 points on the display's surface. Install the expansion board as shown below.

[Installation Method]

Remove the cover of the 4-point expansion board slot.

1 Set the POWER switch on the instrument to OFF.

2 Remove the two screws from the slot cover, and re-

move the cover.

Install the 4-point expansion board.

1 Place the 4-point expansion board along the right-

and left-side guides in the slot.

2 Push the board all the way and make sure that the

board is connected properly.

3 Secure the board with the two screws that were re-

moved previously.

• Repeatability of the measurement value becomes

worse when the fixation by the screw is incomplete.

• To remove the board, remove the two screws first,

then hold the grip of the board and pull it out. After

the board is removed, attach the cover to the slot.

When installing/removing the 4-point expansion board, al-

ways set the POWER switch to OFF and pull the AC power

cord from the AC outlet first.

Do not touch the connectors (gold plated parts) or ICs on the 4-point expansion board with your hands. If oil or

similar matter adheres to the connectors, wipe them with a soft, dry cloth.

The following two types of measuring probes can be connected.

• CA-P02 (cord length: 2 m)

• CA-P05 (cord length: 5 m)

A total of five probes can be connected. When connecting two

or more probes, always make sure that one of them is con-

nected to the probe connector [P1].

Connect necessary number of probes to the probe connectors

[P2] to [P5] on the 4-point expansion board. You do not have

to connect any probes to those connectors ([P2] to [P5]). Probes

can be connected to any connectors ([P2] to [P5]).

The connecting method for connectors [P] to [P5] is the

same as that for [P1]. (Refer to page 26.)

Notes when connecting probes: Probe connectors on the 4-point ex-

pansion board where no probe is connected must be capped.
