2. Installing the 4-Probe Expansion Board CA-B15
Installing the optional 4-Probe Expansion Board CA-B15 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]
1. Remove the cover of the 4-Probe Expansion Board slot.
1 Set the POWER switch on the instrument to OFF(●●).
2 Remove the two screws from the slot cover, and remove the cover.
2. Install the 4-Probe Expansion Board.
1 Place the 4-Probe 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 con-
nected properly.
3 Secure the board with the two screws that were removed previ-
ously.
• 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.
<Notes on Installation>
● When installing/removing the 4-Probe Expansion Board, always 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-Probe Expansion Board with your hands. If oil
or similar matter adheres to the connectors, wipe them with a soft, dry cloth.
<Connecting Measuring Probes>
The following 8 types of measuring probes can be connected.
●
LED Universal Measuring ø27 Probe CA-PU32 /CA-PU35
●
LED Universal Measuring ø10 Probe CA-PSU32/CA-PSU35
●
LED Flicker Measuring ø27 Probe CA-P32 /CA-P35
●
LED Flicker Measuring ø10 Probe CA-PS32 /CA-PS35
A total of five probes can be connected. When connecting two or more probes, always make sure that one of them
is connected to the probe connector [P1].
Connect necessary number of probes to the probe connectors [P2] to [P5] on the 4-Probe 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 Measuring Luminance Range will vary according to the type of Measuring Probe.
6 types of optionally available Measuring Probes can be connected.
As a display model to be measured and the Measuring Luminance Range of Measuring Probe will vary according
to the type, please install one that is fit for your use. Also, different types can be coresident.
● The connecting method for connectors [P2] to [P5] is the same as that for [P1]. (Refer to page 26.)
Notes when connecting probes: Probe connectors on the 4-Probe Expansion Board where no probe is connected must be capped.
**Flicker Mode is a function which can be used only when LED Flicker Measuring ø27 Probe(CA-P32/35) or LED Flicker Measuring ø10
Probe(CA-PS32/35) is connected.
