UltraScan PRO Features
The UltraScan PRO is a dual beam xenon flash spectrophotometer with a wavelength range from 350
to 1050 nanometers (nm). All tristimulus integrations are based on a triangular bandpass having a full
width half max of five nm and are calculated per Paragraph 7.3.1 of ASTM Standard E308. The
wavelength interval is five nm.
The sensor uses an integrating sphere that is six inches in diameter and coated with Spectraflectto
diffuse the light from the three installed xenon flash lamps. One of the lamps provides light in the UV
region only, one provides IR light only, and the third provides light across the spectral range. The
instrument can measure both reflected and transmitted color of products.
Figure 1.The UltraScan PRO
Note: Dropping the instrument or using it in a manner not specified by the
manufacturer may impair the protection afforded by the equipment. Danger of electric
shock if liquids are spilled and fire if volatile liquids are spilled. Use care when
measuring liquid samples.
The UltraScan PRO possesses the following default features:
•Reflectance port
•Sample Clamp
•Transmittance compartment
•Specular-Included/Excluded Port
Reflectance Port
The reflectance port is located at the front of the sensor. The port is covered by a spring-loaded sample
clamp which is used to hold the specimen in place during measurement. Two guidance holes are
present to aid in placement of the white tile and light trap at the reflectance port. When the small area
of view lens is in use, the small area or large area port plate is installed at the reflectance port.

Sample Clamp
The UltraScan PRO includes a spring-loaded sample clamp that can be used to hold samples flat and
securely at the reflectance port. The clamp has two buttons, one which raises and lowers the arm, and
one that moves the clamp toward and away from the reflectance port. The white line at the bottom of
the clamp marks the appropriate clamp position for standardization; in this position both the light trap
and white tile may be placed at the reflectance port by simply pulling back the spring-loaded head of
the clamp.
A magnetic white ceramic disk on the face of the clamp provides a consistent white background for
measurements. A non-slip, magnetic black pad is also included that can be used to replace the white
disk for applications that require a non-slip or dark backing. To change to the pad, simply pop out the
white disk and insert the non-slip pad.

.
Specular Included/Excluded Port
The UltraScan PRO sphere contains a specular exclusion port door which is closed during specular
included and transmittance measurements and opened during specular excluded measurements. The
position of the door is controlled through the software. See the ULTRASCAN PRO STANDARDIZATION
section for more information on the various measurement modes.
Figure 5. Specular Exclusion Port Closed

Figure 6. Specular Exclusion Port Open
The UltraScan PRO features automated specular included/excluded port control and sensing. This
feature allows you to set the port to the desired position from EasyMatch QC. The software reports the
position, thereby allowing errorless measurements.
Indicator Lights
The UltraScan PRO’s indicator lights let you know what mode of standardization is currently in use.
The top light indicates that power is on. The second light indicates that the specular exclusion port is
open. The third light indicates that small or medium area view is in use, and the bottom light indicates
that the Ganz-Griesser UV filter calibration is in use.
Figure 7. Indicator Lights
Automated UV Control
The UltraScan PRO performs a Ganz-Griesser calibration, which uses a 400-nm UV filter to achieve and
maintain the proper ratio of the energy in the UV region of the electromagnetic spectrum to that in the
visible region of the spectrum. This improves the agreement of the illumination between different
instruments and keeps illumination constant as the instrument’s lamp ages. This calibration should be
used when measuring colors that fluoresce due to illumination by light in the UV range of the
electromagnetic spectrum (such as optically-brightened whites).
For the Ganz-Griesser calibration, a stable, fluorescent white transfer standard marked with an
assigned Ganz whiteness (normally assigned in reflectance-specular excluded mode) is used to set the
correct illumination conditions. The assigned value is traceable to a four-step cotton white scale

calibrated by the Hohenstein Institute in Germany. Instructions for using UV control are described in
the Standardization section.
Medium Area View and Small Area View
The medium area view (MAV)/small area view (SAV) feature includes MAV and SAV lenses, port plates,
and a retroviewer (lamp in the sphere that allows viewing of the sample in a flip-up mirror for
determining the proper placement of samples). To use the MAV/SAV feature:
1. Remove the original port plate from the reflectance port and replace it with the MAV or
SAV port plate, as desired.
2. Standardize the instrument. Be sure to select 0.390 inch (9.906 mm) [MAV] or 0.190 inch
(4.826 mm) [SAV] as the area view in the Setup Mode window in EasyMatch QC. The lens
will automatically adjust.
3. Place the sample at the reflectance port.
4. Press the retroviewer switch on the top left of the sensor (about halfway back). The sample
is illuminated, and an image appears on the screen on the top of the sensor. If necessary,
adjust the door above the screen to see a mirror image of the screen display.
5. Be sure that the sample completely covers the reflectance port. Adjust the position of the
sample if necessary.
6. Read the sample.
The RETROVIEWERlamp has two modes of operation. Select the desired mode of operation using the
retroviewer button as follows:
1. Lamp Stay on Mode:Press and hold the retroviewer button until a beep is heard. To turn
the lamp off, press and immediately release the retroviewer button three times in a row.
2. Lamp Turn Off Mode:Press and immediately release the retroviewer button. The lamp will
automatically turn itself off when you take a reading.
Note: To prevent heat build-up, the lamp will turn off automatically after four minutes
of inactivity, regardless of the selected mode.

UltraScan PRO Functions
The UltraScan PRO must be standardized on a regular basis to keep it operating properly.
Standardization sets the top and bottom of the photometric scale. During standardization, the bottom
of scale is set first. For this, you simulate the case where all the light is absorbed by the sample. For
UltraScan PRO, the bottom of scale is set with the light trap for reflectance. The light blocker (a.k.a.
black card) is used to set the bottom of scale for transmittance measurements.
Top of scale is then set by scaling the light which is reflected or transmitted to a calibrated standard.
This is done using a calibrated white tile for reflectance measurements. For top of scale in
transmittance, you are prompted to place the white calibrated standard at the reflectance port.
Alternatively, a plug of barium sulfate (BaSO4) or magnesium oxide (MgO) may be used to more closely
approximate the actual sphere wall reflectance. When taking transmittance measurements, the
calibrated white tile or the plug used during standardization must be kept at the reflectance port.
When the instrument is to be used for transmittance measurements of liquids, a clear liquid (distilled
water for water-based samples, toluene or benzene for resins, or mineral oil for oils) in a cell of the
desired size should be used to set the top of the scale.
It is recommended that the instrument be standardized at least once every eight hours. Also,
standardize the instrument whenever the hardware changes, such as the placement of the UV filter or
with any environmental changes, such as temperature.
Sensor > Standardization
Four modes of measurement are available when you standardize the UltraScan PRO:
•RSIN: Reflectance - Specular Included
•RSEX: Reflectance - Specular Excluded
•TTRAN: Total Transmittance
•RTRAN: Regular Transmittance
With varying hardware configurations such as UV filter in/out and the different areas of view, there are
many ways to standardize the UltraScan PRO. The instrument can be standardized at any time by
selecting SENSOR > STANDARDIZE or by clicking the STANDARDIZE button on the default toolbar. You
are first prompted to indicate the instrument configuration.
Place the cell in the transmittance compartment as close to the sphere as possible for measuring total
transmittance. Place it as close to the lens as possible when measuring regular transmittance.

UltraScan PRO Supplemental Manual for EasyMatch QC Ver. 2.0

Sensor > Configure Multi Mode
This command is used to set up the process by which the instrument can standardize and read in two
separate but similar modes when the standardization and read commands, respectively, are given.
The following screen first appears that allows you to indicate how you would like the multimode
readings to be performed.
Figure 17. Configure Multi-Mode
When this screen first opens, the standardization modes you have configured for your instrument
(using SENSOR > SET MODES) are listed in the AVAILABLE MODES box. Click on the first mode you wish
to use and then click the INCLUDE button to move the mode from the Available Modes box to the
Selected Modes box. Only modes that are similar enough to the already-selected mode that no user
intervention is required for the dual measurements will remain available. Select the second desired
mode and click INCLUDE again to include it. Click OK. Then, when the OPTIONS > READ METHOD
menu is set as MULTIPLE READ MODE, the instrument will be standardized in the two modes when
you initiate standardization and will read in the two modes when you initiate readings. The multiple
readings are placed in the job as separate measurements.

Figure 19. Setting Top of Scale TTRAN
Note: Closing the transmittance compartment door while making transmittance
measurements is the best practice for this instrument. However, when measuring the
transmittance of liquids that are volatile and/or toxic, it may be more important to
measure the samples quickly than to eliminate ambient room light. To see if leaving
the door open will adversely affect your color measurements, standardize the
instrument in the desired transmittance mode with the transmittance compartment
door closed, then measure either air or a typical sample with the door open and then
with the door closed. Compare the measurements. If the difference is acceptable under
your measurement method, you may measure your samples with the door open. This
test should be repeated if the instrument is moved to a new location.
Sensor > Setup Mode (UV Filter)
Each UltraScan PRO is factory fitted with a UV filter to exclude UV content in a measurement. The
procedure is to standardize in 2 modes –one with the UV Filter Out-Of-View and one with the UV Filter
In-View for comparison. In this way, a numerical value for the ultraviolet contribution can be
documented.
Figure 20. UV Calibration Mode Settings
•UV Filter Nominal position is set at factory and never changed. All Diagnostic test programs
are run with the UV Filter in the Nominal position to establish a consistent optical path for
the test across a model line. Some instrument models have motorized UV Control as an
option. If the instrument does not have the option, the UV Filter will be fixed at the Nominal

UltraScan PRO Supplemental Manual for EasyMatch QC Ver. 2.0
20
position. The instruments with motorized UV Control move the UV Filter insertion to that
position.
•UV Filter IN creates a UV-excluded measurement for UV optically-brightened agents. The
UV Filter is inserted 100% to exclude UV. This option allows the user to negate the effect of
optically-brightened agents or when used in multimode with UV Filter Nominal or UV Filter
Calibrated, determines the amount of optical brightening agents present.
•UV Filter Calibrated creates a UV-included measurement for UV optically-brightened
agents). This UV calibration procedure optimizes the UV content to match D65 Daylight over
time using a Fluorescent Standard with an assigned WI Ganz value. Once calibrated to the
Fluorescent standard (available as an option) with the UV filter inserted into the light path
such that the measured WI Ganz value matches assigned WI Ganz value for the Fluorescent
standard. This UV CAL filter position is fixed and user-set until the next UV Calibration.
•UV Filter Custom can create one of more UV Filter states where the UV Filter insertion point
is custom set by the User.
UV filter calibration should be performed weekly and after lamp replacement. Once SENSOR > UV
FILTER CALIBRATION is chosen, the following screen appears.
Figure 21. UV Calibration
Enter the standard’s ASSIGNED VALUE into the appropriate box on the UV Calibration screen. This
value has been assigned at the factory if you are using the HunterLab-supplied fluorescent standard.
Also choose whether the value is for BRIGHTNESS 457, WHITENESS INDEX CIE (and the
illuminant/observer combination), WHITENESS INDEX GANZ, or Z%. The scale used in the example will
be WI Ganz for a HunterLab standard.
Figure 22. UV Calibration with WI Ganz
Select CALIBRATE UV to automatically adjust the UV filter to the appropriate position after several
readings of the fluorescent standard. First you are prompted to place the fluorescent standard at the
port.
