Features
Automatic Shut-Off
To increase battery life, the instrument automatically
turns itself off if it is not used within a user-defined
time—between 10 and 120 seconds. See Setting
Instrument Configuration, Section Four for more
information. The instrument turns back on whenever a
key is pressed, measurement taken, or when the adapter is
plugged in.
Patch Smarts Recognition
Several functions within the instrument incorporate a
feature that automatically recognizes patch types. This
"patch smarts" feature attempts to characterize a paper,
solid, tint, or overprint patch. After a measurement, the
highlight cursor in the measurement list automatically
moves to the predicted measurement item, regardless of
its previous placement. This feature can be disabled in the
instrument configuration menu.
Drag-n-Drop Override
Several functions incorporate a "drag-n-drop" feature,
allowing you to reassign measured data to a different
measurement item. To do this, simply move the highlight
cursor with the tab keys to the appropriate measurement
item while holding the instrument down to the shoe. For
example, if a tint measurement is taken and the data
appears as a solid, you could override the result by
keeping the instrument down and tabbing the highlight
cursor to the tint measurement item.
Hi-Fi Color Capability
The instrument does more than just measure the density
of special colors—such as HiFi Color™. Instead, it
captures their unique spectral identities and transforms
them into useful color information.
OVERVIEW AND SETUP
1-3
Unpacking and Inspection
After removing the instrument from the shipping carton,
inspect it for damage. If any damage has occurred during
shipping, immediately contact the transportation
company. Do not proceed with installation until the
carrier’s agent has inspected the damage.
Your instrument was packaged in a specially designed
carton to assure against damage. If shipment is necessary,
the instrument should be packaged in the original carton.
If the original carton is not available, contact X-Rite to
have a replacement carton shipped to you.
Shoe Lock Operation
To take measurements with the instrument, you must
unlock the shoe. When the instrument is not in use, the
shoe should be re-locked to protect the instrument optics.
A rotating latch on the bottom of the instrument locks the
shoe closed.
• To unlock, hold shoe against the instrument and
rotate latch. Align latch so that it fits through the
cutout in the shoe. Carefully release the shoe to open.
• To lock, hold shoe against the instrument and rotate
latch to catch the detents in the shoe.

Applying Power
The Battery switch—located on the bottom of the
instrument—turns the instrument off and on during battery
operation. When the AC adapter is attached, the instrument
remains on and the battery switch has no affect.
As an added feature to conserve battery life, the
instrument automatically powers down when it is not in
use. You can define the amount of time it takes to initiate
a power-down within the instrument configuration
options, see Section Four. Taking a measurement or
pressing a key turns the instrument back on during a
power-down.

OVERVIEW AND SETUP
1-5
Charging the Battery Pack
Four, AA nickel-metal hydride batteries fastened in a
removable battery pack power the instrument. The battery pack
must remain in the instrument at all times for proper operation.
Before initial “remote” use of the instrument, charge the battery
pack for approximately three hours. However, if immediate use
is required, the instrument can be operated “tethered” to the AC
adapter after a short period of battery charging.
NOTE: Only use the AC Adapter supplied or the optional battery
charger (X-Rite P/N 500CHG) to charge the battery pack. A "Low
Battery" message appears on the display when the battery falls
below approximately 25% of full charge. Measurements are still
possible, but the battery should be charged soon. A "Charge Battery"
message appears when not enough battery power remains to take a
measurement. The battery must be charged immediately.
To attach the AC adapter:
1. Verify that the voltage indicated on the adapter complies
with the AC line voltage in your area. If not, contact
X-Rite or an authorized representative.
2. Insert the small plug from the adapter into the power-
input connector on the instrument. (If you are using Serial
Cable SE108-92, you can plug the small plug into the
power connector at the end of the cable.)
3. Plug the detachable line cord into the adapter.
4. Plug the line cord into an AC wall receptacle.

Important Measurement Techniques
In order for the instrument to obtain accurate and
repeatable measurements, the bottom of the shoe must be
flat with the surface to be measured. When measuring
curved items where a flat surface is not available, a
fixture should be used. A fixture allows accurate
positioning of the sample tangent to the measurement
plane. If the item to be measured is smaller than the shoe,
you may want to make a platform—at same height as the
item—for the rest of the instrument to sit on.

3. Instrument Calibration
General Information 3-1
White Calibration 3-1
Full Calibration 3-3
General Information
Under normal circumstances, the instrument should be calibrated
at least once a day. Calibrating the instrument every day ensures
the best measurement accuracy and stability. However, you can
customize the amount of time you would like to elapse between
calibrations. Varied time intervals can be set allowing the
instrument to notify you when a calibration is required. Refer to
Setting Calibration Intervals in Section Four, Configuration.
White Calibration
IMPORTANT: Every white calibration reference has a set of reflectance
values that are unique. Use the calibration reference only if the reflectance
values match those of the instrument you are calibrating. The calibration
reference shipped with an instrument is marked with a matching serial
number. If a different calibration reference is used, the reflectance values
for that reference must be entered in the instrument. Refer to Entering
Reflectances in Section Four if the values need to be modified.
The White Calibration function is used to update the
white calibration point in the instrument.
• Use the Tab Up $ or Tab Down @ key to highlight
Calibration. Press the Enter key # to access the white
calibration function.
Positioning the Instrument on the White
Calibration Reference
NOTE: Make sure the calibration reference is clean before use. Refer
to the calibration cleaning procedure in Section Seven.
