1. Measurement Principles and Characteristics
■ MeasurementPrinciples
This device measures powder whiteness according to our own uniquely
developed standards. It measures reectivity and utilizes two blue LEDs as its
light source. The light from the blue LEDs is passed through a diffuser panel and
shined onto the sample surface at 45 degree angles from both the left and right.
A photo diode measures the amount of reected light. The whiter the sample, the
more light is reected back and detected and thus a higher measurement value
is registered. The LEDs are a blue color with a 466nm center wavelength. They
are adjusted to provide a similar measurement that the previous model (C-100)
created when used with it’s blue lter. In addition to having a starch calibration
curve built in as the base calibration curve, a function allowing the user to set
their own calibration curves is also included, making it possible to measure the
whiteness of a variety of powders.
■ Characteristics
The new C-130 model is smaller and more compact than our previous C-100
model. Furthermore, using blue LED light sources allow for a longer light source
lifetime reduced power consumption and reduced heat generation. In addition,
the required sample size has been greatly reduced. Using starch as an example,
about 13.5g of sample was required in the C-100. The C-130 only requires
approximately 5.5g of starch, Not only has ease of packing of the sample been
improved, but the amount of time spent preparing for the measurement has been
reduced. Finally, sensitivity calibration when the device is turned on has been
reduced, allowing measurements to begin must faster than with previous models.

5-1.Connecting the power cord
[Caution] Power supply voltage may be different when using
this product in other countries. Please only use a
power cord designed for your country.
(1) Insert the power cord into the power supply connector on
the rear of the main unit.
(2) If the power supply is a three-prong plug 100V-120V outlet,
insert the power cord into VAC outlet. (See the right gure and in
case of 100V-120V use with the blade plug connector). Connect
the included power plug conversion adapter into the power cord
first, then plug the cord into a 100V-120V power outlet. Next,
connect the ground wire on the power cord to the ground.
[Caution] If 200V-240V outlet is used, power cord B should be used.
[Caution] Ifthepowersupplyis200V-240Vwithaatbladeplug,
the conversion adapter should be prepared by yourself.
[Caution] If the power supply is 100V-120V with a round pin plug,
the conversion adapter should be prepared by yourself.
5-2. Whiteness standard plate set
As shown in the diagram, insert the whiteness standard
plate into the drawer of the main unit and close the drawer.
[Note] To ensure proper placement of the whiteness standard
plate, there is a pin that protrudes from the bottom.
Make sure the pin goes into the hole in the drawer.
[Note]
Be sure not to touch or scratch the hole on whiteness
standard plate. If it gets dirty, clean it with the glass cleaner.
[Note] Keep the whiteness standard plate in the case when
not in use. Use the magnetic bottom of the case to
hang it in a convenient place (or on the instrument).
5-3. Starting up the main unit
(1) Turn the power switch located on the back of the main unit
to ON..
(2) [WARMING-UP] is displayed. Dots will flash for about 20
seconds.
[Note] If the whiteness standard plate is incorrectly
placed, when you turn on the power switch, [Insert
STD] or [Error 01 Leak] will display. If this occurs,
correctly insert the whiteness standard plate into
the drawer (see 5-2).
(3) When powering up, if the machine is set to standard plate
check mode, the whiteness standard plate value will display.
(4) If you press the key, it will change to measurement
mode and ‘CHECK STD’ will disappear.
(5) Remove the whiteness standard plate.

6. Measurement
6-1.How to pack the sample
(see the separate ‘Simple Guide to Sampling’)
[Note] The following is the standard measurement
method for starch. Different packing methods will
apply to samples with larger diameters, viscosity,
moisture, runny sample, etc.
(1) Heap the sample onto the sample platter.
(2) Use the spoon with spatula to pack down the sample.
(3) Use the spoon with spatula to level off the sample to the
height of the edge of the sample platter.
[Note] An accurate measurement cannot be taken if there
are cracks or lumps in the surface of the sample.
Use the spatula to make the surface as flat and
smooth as possible.
[Note] When the surface of the sample to be measured is
asataspossible,themeasurementwillbevery
accurate.
[Note] If powder sticks to the outside or bottom of the
sample platter, clean it with the brush. Powder
stuck to the sample platter may cause it to tilt,
resulting in the measurement not being accurate.
While cleaning the sample platter, the spatula may
be used to hold down the sample and keep the
surfaceatandsmooth.
[Note] Depending on the sample, contact with the air may
cause drying or an increase in moisture content.
When handling such samples, it is necessary to
move quickly to the next operation after packing
down the sample.
[Note] If several samples are measuring at the same time,
Sample Platter Holder is useful in this purpose.
[Caution] Before performing any measurements, use the glass wiper
tocleantheglasslterofthemainunit(referto8.1).

6-2. Setting the sample platter
Open the drawer and place the sample platter inside the
drawer.
[Note] If there are any contaminants stuck in the area
where you place the sample platter or drawer, the
platter will tilt and it will not be possible to get an
accurate measurement. Always keep the inside of
the drawer clean.
6-3. Closing the drawer
Slowly, completely close the drawer.
[Note] Light entering through any gaps may make
accurate readings impossible.
[Note] Impacts while closing the drawer may cause
cracks in the sample surface, leading to inaccurate
measurements. Please slowly close the drawer.
6-4.Measurement
After closing the drawer, the calibration curve number, the
number of the measurement and whiteness value will be
displayed automatically.
[Note] If the reading is outside of the measurement
range, UNDER or OVER will be displayed.
 ■SelectingtheCalibrationCurve
The C-130 can have up to ten calibration curves. [01] is
for the base calibration curve, and [02-10] provide for nine
additional customer calibrations that can be stored and later
retrieved.
[Note] The factory setting is the base calibration curve [01].
[Note] Please refer to [7. How to Make a User Calibration
Curve] for information on how to register a user
calibration curve.
(1) Set the whiteness standard plate.
(2) In Measurement Mode, use the key to select the
calibration curve input mode.
(3) The instrument restarts after you input your desired
calibration curve number and press the key.
(4) The main unit startup procedure follows the same sequence
(refer to 5-3) and returns to measurement mode. At the
time of measurement, the calibration curve number will be
displayed.
