Changing the Aperture
NOTE: The 964 instrument includes all three apertures.
The instrument was designed to allow you to quickly change
the aperture and target window. X-Rite provides three aperture
sizes especially designed for the instrument.
Available sizes:
4mm, 8mm and 16mm.
Refer to the next page for illustrations.
To change the aperture size:
1.
Unplug the AC adapter and click the battery switch to Off.
2.
Hold the shoe next to the instrument housing and lift
upward on the spring-loaded latch. Open the shoe
perpendicular to the instrument housing.
Refer to
Unlatching the Instrument Shoe in Section One.
3.
Carefully rotate the instrument over and rest it on its top.
4.
Using your fingers, rotate the sensor nose to the left
(counter-clockwise) until it stops.
5.
Carefully remove the sensor nose by lifting upwards and
set aside.
6.
Position the appropriate end of the aperture wrench on the
existing aperture and remove by turning to the left
(counter-clockwise) until it is free. Set existing aperture
aside.
CAUTION: Extreme care should be taken not to contaminate the
optics with any dust or dirt when installing the new aperture.
7.
Align new aperture over opening in optics and secure by
using the appropriate end of the aperture wrench.

Position corresponding sensor nose over the optics opening
in the bottom housing and rotate to the right (clockwise)
until it stops.

Using your fingers, press the target window out from the
topside of the shoe. Press against the ring and not the clear
window.
