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.

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).

10
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.

 ■AverageValue
This device can display the average value for 2-9
measurements. After measuring 2-9 times, press the
key and the average value, in addition to the number
of measurements, will display. Displaying the average
value deletes all previous values and makes the next
measurement the rst measurement of the next set.
The number of measurements is displayed after each
measurement. However, the display will show 1 in the
following situations:
(1) After pressing the key
(2) After the number of measurements has reached 9
(3) After changing to Standard Plate Check Mode
(4) After changing the calibration curve number
6-5. Adjusting for Sensitivity
After performing measurements for a long period of time,
the sensitivity of the device may need to be re-calibrated.
Therefore, the sensitivity must be periodically checked.
[Caution] If a sensitivity adjustment is required, [C] will be
displayed in the upper right corner of the display.
(1) Press the key, and [CHECK STD] will display. You can
then switch to the Standard Plate Check Mode.
(2) The value of the whiteness standard plate will be measured if
you place the whiteness standard plate and close the drawer.
(3) Sensitivity is misaligned when the measured value and
the value recorded on the whiteness standard plate do
not match. While the whiteness standard plate is still in
the machine, press the key and the sensitivity will be
automatically adjusted.
(4) Press the key to switch from Standard Plate Check Mode
back to Measurement Mode. [CHECK STD] will disappear.
(5) Remove the whiteness standard plate.
[Note] The whiteness standard plate can be measured
during Measurement Mode. While the reading may
be different during Standard Plate Check Mode,
this is not unusual.
[Note] For accurate whiteness measurements, it
is important to regularly adjust instrument
sensitivity (the brightness of light). You are more
likely to see the [C] indicator in the top right of
the display either immediately after startup or
when substantial humidity changes alter the light
transmission near the LEDs.

7-1. About user calibration curves
For users of previous models (C-100), measurement
values compared to those of previous models may be
different when measuring samples other than starch.
Additionally, there may be a need for a different
calibration curve than the factory standard provided,
depending on the measurement requirements (e.g.,
customer internal standards).
In such cases, it is possible to calculate the reading by
creating a user calibration curve.
[Note] You can register up to 9 user calibrations from
[02] to [10].
7-2.Creating a calibration curve
(1) Sample preparation
Prepare 5 samples of various whiteness levels.
Samples should include the upper and lower limits of
the whiteness values you intend to measure. As an
example, if you wish to measure whiteness between 40
and 95, you should include a sample with a whiteness
of approximately 40 and a sample with a whiteness of
approximately 95.
(2) Reading the sample
Read the prepared sample using the machine’s by
Measurement Mode (Base Calibration Curve [01]),
Measure the sample using the previous instrument or
the user’s standard method.
(3) Record the sample readings per Table 1.
(Please copy and use the Creating a Calibration Curve
Table, P.18)
[Caution] When making the table, rank the whiteness
values of 130’s should be from smallest to
largest.
[Note] It cannot be used when there is no calibration
curve of a graph at upward slant to the right.
(Figure 2)
[Note] At least two samples should be used when
creating a calibration curve. If less than five
samples are used, repeat the largest value
for the remaining items. As an example, when
three samples are used, sample three values
shouldberepeatedforsamplefourandvein
both columns.
