Operation Manual
I Introduction
To keep the scale working efficiently
The PPC-300WP is rated IP68 (waterproof) when it has been closed by Yamato authorized technicians using Yamato approved equipment and procedures. When closed by other technicians
or methods, the PPC-300WP is only rated IP65 (washdown).
Do not place the scale in an area exposed to direct sunlight, wind currents, fire or steam, otherwise, the measurements will not be accurate.
Do not place the scale near machines that create vibrations or electromagnetic disturbance, such
as microwave ovens, portable phones, or large motors. This will affect the accuracy.
The operating environment is a work temperature range of –10°C to +40°C (14°F to 104°F) and a
humidity range of 30% RH to 85% RH. Do not subject the scale to sudden temperature changes. Allow the scale to adjust to new temperatures before use. For example, a 10°C change in
temperature will require approximately 5 minutes before thermal equilibrium is reached.
If the scale is sealed as legal for trade, do not break the seal. If you break the seal, the scale will
not be considered legal for trade. In this case, contact your dealer.
Do not disassemble or modify the scale, you will void the warranty. Modified scales may not be
legal for trade and may loose thier IP rating.
Remove the batteries when using the AC adapter. The scale will continue to draw power from the
batteries, if they are installed, even with an AC adapter connected.
Place the scale on a flat stable surface that will support the scale and the load.
Use only parts and modifications specified by Yamato. Yamato cannot be held responsible for
problems caused by modifications or parts not specified by Yamato.
If dust or foreign matter becomes lodged in the lower diaphragm chamber, remove it following the
instructions in Cleaning the Lower Diaphragm.
End of life disposal
Dispose of all electronic equipment in accordance with all applicable laws and regulations.
Cleaning
If the scale becomes dirty, clean it with a soft cloth and clean water. For stubborn stains, apply a
little neutral detergent and then wipe the scale with a dry cloth.
When sanitizing the stainless steel platform and platform support with hypochlorous acid; use a
concentration of 200 ppm or less, soak for 5 to 10 minutes, rinse with clean water and dry with a
clean cloth.
When sanitizing the scale body with hypochlorous acid; spray the scale with the hypochlorous
acid solution, rinse with clean water and dry with a clean cloth.
When cleaning the scale with an alchol solution; use a concentration of 80% or less, rinse all plastic parts and the overlay with clean water and dry with a clean cloth.
When cleaning the scale with mild detergent; place the detergent on a sponge or cloth, use the
sponge or cloth to clean the scale, rinse with clean water and dry with a clean cloth.
Do not submerge the scale body in liquid to clean it. This will prevent deterioration of some of the
plastic components.

Operation Manual
IVUsing the Scale
Selectable Functions
The PPC-300 family of scales offer three selectable functions to assist you with your weighing needs.
These functions are packing, checkweighing and grading. Each of these functions are programmable
by the operator to give you the flexibility to adapt the PPC-300 to your processes. User setup parameter 01 controls which, if any, of these functions is enabled.
Parameter 01=000
None of the functions are enabled.
Parameter 01=001
The packing function is ideal for filling containers. The numeric display indicates the weight that needs
to be added or removed from the platform to reach the target weight. The bar chart gives a graphical
representation of the loaded weight in relationship to the target weight for quick reference. Up to 99 different setups can be stored for later recall. Available options include a flashing indication to announce
an acceptable, unacceptable, under, or over weight condition; and an auto-tare feature that automatically tares off the container weight at the beginning of each weighment. The packing function is not
legal for trade.
Parameter 01=002
The checkweighing function uses a lower limit and upper limit to establish an acceptable weight range
for portioning, quality control and filling while displaying the weight loaded on the platform. The bar
chart gives a graphical representation of the status of the loaded weight in relationship to the upper
and lower limits for quick reference. Up to 99 different setups can be stored for later recall. An optional
flashing indication announces an acceptable, unacceptable, under, or over weight condition.
Parameter 01=003
The grading function allows you to defined up to 15 continuous weight grades and displays the grade
of the current load. This facilitates quick, error free sorting by the operator without a need to consult or
memorize grade charts. Anywhere from 12 to 66 different setups can be store for later recall, depending on the number of grades within each setup. Available options include a flashing indication to announce a weight above the minimum grade, and a stability function that lets you choose to have a real
time grade display or to require a stable reading before the grade is displayed. The grading function is
not legal for trade.
More details on each of these functions and setup examples are available on the following pages.

Grading Function
The grading function allows you to defined up to 15 continuous weight grades and displays the grade
of the current load. This facilitates quick, error free sorting by the operator without a need to consult
or memorize grade charts. Anywhere from 12 to 66 different setups can be store for later recall, depending on the number of grades within each setup. Available options include a flashing indication to
announce an acceptable weight grade, and a stability function that lets you choose to have a real time
grade display or to require a stable reading before the grade is displayed. The grading function is not
legal for trade.
Enable
1. To enable the grading function, press the

IVUsing the Scale
Grading Function
Once the grading function is enabled, the grade weights need to be setup. Each weight entered is the
lowest acceptable weight for that grade. This example will setup three grades. The first is from 8.00 to
9.99 lb. The second is from 10.00 to 11.99 lb. The third is from 12.00 to 18.00 lb. Since parameter 02
is set to 003, the scale will prompt for four weights. The weights for this setup will be 8.00, 10.00, 12.00
and 18.01 lb.
Setup
1. With the scale on and the platform empty, press the
key for one
second. The scale will indicate that it is in grading setup mode and
the
indicator will flash.
2. Up to 66 different configurations can be stored in memory. Initially,

4. Use the
key to select a digit to change, and the
and
keys
to decrease or increase the digit's value. Example: Press the
key
eight times to change the digit to "8". Press the
key to save this
weight and advance to the next grade.
5. Enter the second grade weight. Example: Press the
key three
times to select the fourth digit. Press the
key once to change the
digit to "1". Press the
key to save the second weight and advance
to the next grade.
6. Enter the third grade weight. Example: Use the keys to enter 12.00
lb. Press the
key to save the third weight and advance to the final
weight entry.
7. Enter the final weight. This will be the lowest unacceptable weight
above the final grade. Example: The final grade is from 12.00 to
18.00 lb, so enter 18.01 lb (one division above 18.00 lb). Press the
key to save the final weight and exit setup mode.
The scale will not accept a grade weight that is equal to or less than the previous grade weight.

IVUsing the Scale
Grading Function
This is an example of how the grading function operates once it has been enabled and setup. The
setup for this example has grades of 8.00 to 9.99 lb, 10.00 to 11.99 lb, and 12.00 to 18.00 lb. The
scale is set to display real time grade values. The flashing display is not enabled.
Operation
1. The scale should display the grading setup that is active, 05 in this
example. The
, stable and center-of-zero indicators should be
displayed. The rightmost two digits should display underscores. This
indicates that the current load is below the lowest grade.
2. If you wish to enter a tare, place the item on the scale platform and
press the
key. The net weight indicator should be displayed, and
the center-of-zero indicator should not.
3. Load the scale with the product to be graded. If the product falls at or
above the first grade setpoint, and below the second grade setpoint,
then grade 01 will be displayed.
4. If the product falls at or above the second grade setpoint, and below
the third grade setpoint, then grade 02 will be displayed.
5. If the product falls at or above the third grade setpoint, and below the
final grade setpoint, then grade 03 will be displayed.
6. If the product falls at or above the final grade setpoint, then two overscores will be displayed.
7. Remove the product and any tared item. If a tare was entered, press
to clear it. Press the
and
keys to toggle between the
checkweighing function and the normal weighing mode.
If parameter 04 is set to 001 (stable weight reading required), then the
scale will display two dashes on the right until the weight reading is
stable.

This parameter only applies to the PPC-300WP.
04 - Grade Stability
The grading function can be set to either show a real time display of the calculated grade, or to show
no grade value until a stable weight reading has been acheived. If this parameter is enabled (001) then
the scale will display two dashes in place of the grade value until the weight reading is stable. Then it
will display the appropriate grade.
05 - Auto-off Timer
The PPC-300 series of scales can be set to automatically turn off after a specified time with no activity.
This feature only operates when the scale is using batteries for power.
06 - Automatic Tare
The packing function can be set to automatically tare an initial stable weight, and to automatically clear
the tare when the scale returns to zero.
07 - Flashing Display
This feature is available for the packing, checkweighing and grading functions. For the packing and
checkweigh functions, this feature can be set to operate as specified in the preceeding table. Any setting between 001 and 004 will cause the display in the grading function to flash when any weight above
or equal to the first, lowest grade weight is detected. Setting 005 is only appicable to the PPC-300WP.
21 - Vibration Compensation
Environments that experience "noise" issues caused by external vibration can set this parameter for a
more stable reading at the cost of a longer response time to calculate a stable weight.
