3. Before Making Measurements
1. Please use a AC220V power supply or Batteries (1.5 V
Alkaline “D” size, x4) as the power supply for the PB-3103.
<When using an AC220V power supply>
①Remove the power cord from the power cord
accessories compartment.
②Connect the plug to the socket on the main unit.
2. Insert the crushing
handle in the correct
position.
3. Press the POWER Switch. The Initial screen is displayed.
4. Press the [SELECT] key to match the grain to be
measured, and then select the measurement item.
[Note]
When a name of application to be measured is already
displayed, this operation is unnecessary.
ON OFF
If characters on the display are too dark or light,
perform contrast adjustment (see page 12).
• Before use, leave this unit at the using site to make the
temperature dierence between the unit and enviroment within
2°C. If the temperature between the unit and enviroment is
not homogeneous, the temperature correction is not properly
performed, which may lead to dierences in measured values.
• How to display the unit temperature
Turn on the POWER Switch while holding down the
[SELECT] key in the power-off state. To hide the
temperature, turn o the power.
<When using batteries as the power supply>
Insert 4 size “D” batteries into the battery compartment
on the bottom of the unit, making sure to align the positive
⊕and negative⊖ends correctly. In the case of using
batteries, the power-saving mode is activated, in which
the light amount of the LCD backlight becomes half.
①
②
The measurement item is displayed on the screen
in the following order every time the [SELECT] key
is pressed: "Paddy"→"Milled Rice"→"Parboiled
Rice"→"Parboiled Paddy"→"Tapioca Pellet"→"Tapioca
Flour"→"TEST" →"Paddy" and so on. When the grain
to be measured is displayed, selection is completed.
Item changes every time the key is pressed

4. Sample Taking and Crushing
×
×Too much
Too little
Jast a spoonfull
Themethodofsampletakingandcrushingdependsontheproducts.
<Notes concerning taking of samples>
• The sample amount must be one level of the supplied
measurement spoon without fail.
• When taking samples, extract portions which are
believed to have moisture contents representative of the
average for the entire quantity of cereal. For example,
samples taken from portions which are exposed to
sunlight or in contact with the bottom of the container
are not appropriate representative samples.
• Avoid directly extracting samples by hand, as moisture
from the hands may make it impossible to make accurate
moisture measurements.
• PB-3103 has an automatic sample temperature
compensation function. However, the sample should
be the same temperature as the environment, when the
best possible accuracy is required.

2. Fill to the top of the supplied measurement spoon
with the sample and level o the spoon.
3. Raise the measuring lever, open the crushing
compartment cover, and insert the sample.
4. Turn the crushing handle to crush the sample.
5. Remove the sample dish and shake it lightly to atten
the sample.
1. Insert the sample dish into the sample port
completely so that the front edge comes into contact
with the back of the port.

B.TapiocaFlour
1. Fill to the top of the supplied measurement spoon
with the sample and level o the spoon.
(Remove the excess sample using a pencil or the like.)
2. Spoon out the our into the sample dish and shake it
lightly to atten the our.
3. Place the metal plate on the sample dish.

11
2. Push down the measurement lever until it stops.
3. Moisture value and the
number of measurements
is displayed on the screen.
4. When the same item is measured repeatedly, repeat
the procedure of "4. Sample Taking and Crushing" on
page 8 and later. When a dierent item is measured,
repeat the procedure of the step 4 in "3. Before
Making Measurements" on page 7 and later.
5. When the unit is not to be used over an extended
period of time after a series of measurements is
completed, turn o the Power Switch and unplug the
power cord from the wall socket.
5. Measurements
1. Insert the sample dish fully until the guide line is hid.
The Over Indicator [oL] will be displayed if the
sample’s moisture content exceeds this range, and
the Under Indicator [-oL] will be displayed if the
moisture content is below this range.
[Note]
Although the valid measurement range of the PB-
3103 is shown in specications, values up to 2% of this
range are actually displayed. However, the precision
of moisture values displayed which are outside of the
valid measurement range are not guaranteed. Use these
value readings as rough guides.
[Note]
When measuring tapioca, place a metal plate onto it.
If the measurement lever is pushed down while the
sample dish is inserted incompletely, the upper
electrode or sample dish may be damaged. Be sure to
fully insert the tray.

When the [AVERAGE] key is pressed again the TIMES
display for the next measurement will return to “1”.
The maximum number of measurement times (re-
petitions) is 9. The TIMES display will return to “1”
when measurements are performed 10 times.
<Averagemoisturevalue>
Press the [AVERAGE] key in order to obtain the
average moisture value after making measurements
several times. A point will appear at the lower right of
the TIMES display to indicate that the average value
is being displayed.
AVERAGE
6. Other functions
<Contrastadjustment>
If characters on the display are too dark or light,
perform contrast adjustment. Press the [Contrast]
key. "CONTRAST" is displayed on the screen.
After the contrast adjustment, press the [Contrast]
key again. "Contrast" disappears, and the regular
measurement mode resumes. The adjusted contrast
is saved even after the power is turned o.
To enhance the contrast, press the [SELECT⊕] key, and
to reduce the contrast, press the [AVERAGE⊖] key.
⊕ ⊖

13
<Testing>
Use the supplied checker to check to make sure
that the PB-3103’s electrical circuits are func-tioning
normally. Press several times the [SELECT] key, I will
match the "TEST" display.
Insert the checker into the measurement section and
lower the measurement lever.
15%checker
Normal because the value is
between 14.9 and 15.1%
The electrical circuitry is functioning normally if a
numeric value of 14.9~15.1% is displayed at this time.
Raise the measurement lever and press the [SELECT]
key again, "TEST" disappears, and the regular
measurement mode resumes.
[Note]
In most cases, failure to display a normal value is due to
the presence of dirt in the testing section. Perform the
test once again after thorough-ly cleaning the testing
section if the normal values are not displayed.
<Batterylevelicon>
When the battery is low, the battery level icon (
) appears on the display. When the icon appears,
replace the battery with new ones reference "When
using batteries as the power supply" on page 7.
[Note]
The moisture content may not be properly measured
when the battery level icon displayed.

on the rear panel of the main unit with the cable supplied
with the printer allows users to automatically print the
measured results after measurement.
[Note]
Refer to the operating manual for the printer for how to
set up the printer.

7. Maintenance
Measurement Section
It is very easy for spilled samples to accumulate
in the section where the sample dish is inserted,
so the supplied brushes should occasionally be
used to clean this section. It is particularly easy
for errors to arise if measurements are made when
there is sample material adhering to the electrode
plate (round metal plate).
Crushing Section
If a new sample is crushed when there are still traces
of old samples adhering to the crushing rollers,
the new sample will be contaminated with the old
sample material and accurate measurements will
be impossible. It is therefore necessary to clean the
rollers with the supplied brushes while turning them.
Sample Dish
When using the sample
dish continuously, use
the brush to remove any
sample material adhering
to the inside and back of
the dish.
<Storage>
After using the PB-3103, clean it well as described
above and then store it in a dry place where it will not
be exposed to direct sunlight. Be sure to remove the
batteries if storing the unit for an extended period of
time.
