PLU Pricing Modes
PLU Pricing Modes
11BBy-Weight PLU
PLU is an abbreviation for Price Look Up. The PLU is a reference number assigned to a
product's record including fields such as the description, price, tare, etc.
Different PLU's will have different pricing modes. Meat is normally sold "By Weight" by
the pound or kilogram. Many bakery products are sold "By Count". Other products may
be sold in a standard package that all weigh the same (or assumes all weight is the
same or a minimum value). The different pricing modes are as follows –
Examples of products sold By Weight are meats, cheese, poultry, and produce. ByWeight items can be priced in three ways:
Priced "Per Pound/kilo" - Typically weighed items are priced per pound. The weight
multiplied by the unit price equals the total price of the product.
Priced "Per Fraction of a Pound/100g" (fractional) - The item may also be priced
by the fraction of the pound (where legal and desired). Pricing per 1/4 pound and
per 1/2 pound are available. Kilos are not interchangeable for pounds in this
mode.
12BBy-Count PLU
13BStandard Pack PLU
"Pounds/kilos for price" - The PLU may be sold with a pounds-for-price (rather
than price per pound). For example, “2 pounds for $1.00” rather than
“$0.50/pound.”
Examples of items sold by the count are cookies, donuts, rolls, bread, etc. Example: 4
Apples for $0.69. The By-Count PLU allows the operator to use the scale to print labels.
Pricing is entered as a certain quantity of items for a set price. If the total weight for the
items is needed, a weight field can be configured on the label to print the weight of the
items in addition to the By-Count information.
Examples of items sold by Standard Pack include whole chickens, sheet cakes, bread,
etc. The Standard Pack PLU is similar to By-Count and also allows the operator to print
labels. These labels indicate the net weight and total price of the item. These types of
items all weigh the same (or are assumed to weigh the same or of a minimum value).

PLU Screens
The PLU screen will vary based on the type of PLU that is being displayed: By Weight,
By Count or Standard Pack.
On the PLU screen, if a value field has a border it can be changed for that transaction.
Override the values by touching the box and selecting/entering new values. Note: this is
only a temporary override for this transaction only and the values will revert to the
original the next time the PLU is called.
If the field has no border the value cannot be changed, as determined by Setup
Configuration.

Calling Up PLUs
Calling Up PLUs
When the Impact S® is in Service Mode, the operator screen will display the active
department’s Preset Pages and Preset PLUs.
Note: “Service Mode” is normally the default on the PLU Edit screen. After the product
has been weighed, a label has been printed, and the item has been removed from the
scale, the PLU will clear and the scale will return to the home screen, ready for the next
item.
To begin a transaction, place the item on the weighing tray (can be done after a PLU is
called up).
Call up the PLU (Price Look Up) Record. To do this, find the Preset PLU related to the
product, it may be a By Weight, By Count or Standard Pack item(s). You may also
directly enter the PLU number in order to bring a particular PLU’s data to the screen.
Note: Remember some PLU buttons can link into another page of related items, so you
may need to drill down to find your item’s PLU. Or check that the scale is displaying the
right Preset Page or category for desired PLU. These Preset Page buttons are along the
bottom of the screen and represent PLUs grouped into categories or departments. The
current Preset Page shows a black button, along the bottom. Switch Preset Pages by
touching the desired button.
Once you locate the PLU button touch it to get a detailed PLU screen. The screen will
vary slightly in appearance depending on whether it is By Weight, By Count or Standard
Pack.
Depending on how the PLU has been set up you may be able to edit some of the values
for this current selection. If allowed change items such as Shelf Life, Tare, etc by using a
Temporary Override (see this chapter’s Temporary Override section for details).

Temporary Overrides
Chapter 2: Operating Instructions
Temporary Overrides
Temporary Overrides are certain values can be adjusted for the current transaction only
from within the PLU screen. The changes are temporary and will not be retained in the
original PLU.
If a value can be changed a button will appear around the value. This indicates that the
value can be changed during a transaction.
In the PLU screen above, the Unit Price ($/lb), Tare, Mode, Pack Date, and Shelf Life,
have buttons, indicating they can be changed. The Total Price field does not have a
button and cannot be changed. There is also a button graphic around the Touch to Zero
field, but that does not indicate a changeable field, but rather an interactive one.
To change a value, touch the field. Then depending on the field: enter a numeric value
in the pop-up window using the keypad, toggling to a different within the selected field,
or if there are multiple choices, a new screen will appear and a selection can be made
from that screen.
As always, additional overrides can be found by pressing the OPER button on the
keypad.

Memory Mode
Memory Mode
When the user processes a Memory Mode transaction, he presses the MEM key instead
of the Print key. This will store the transaction data into Memory Mode and return the
user to the Home screen.
If a PLU is added to MEMORY that already exists in MEMORY, it is treated as a separate
entry. This means that it is possible to have multiple transactions associated with the
same PLU.
Making use of items stored via Memory function is simple. Begin with the scale at the
home screen and press the MEM key to bring up a dedicated MEM array. The user will
find Subtotal, RemoveItem and ClearMEM keys available.
In order to make use of data, the user will need to press the Subtotal key. From there,
they will select their MEM entry and press Print when ready.
NOTE: When a PLU is added to MEMORY, the word MEM will display on the main
screen alerting the operator to the presence of data in the MEMORY queue.

Nutrifacts
Selecting the Nutrifacts field will bring up a window that allows you to apply a Nutrifact
entry to a product by its database number.
If the number is not recognized you may select “add” on the next popup, or if you
simply wish to edit the Nutrifact entry, then you will be taken to this screen, where you
may further define your preferred data.
Label – allows the user to determine if the Nutrifact information will print on the main
label in its short-form or if it will print on a second label of its own. This menu also
allows the user to determine which of the two labels (if chosen) will be printed first.
Template – vertical, vertical simplified, tabular, tabular simplified, horizontal, etc.
These choices allow the user to orient the Nutrifacts in a particular direction so as to
make the best use of the label’s space. The simple modes only print the main box of a
Nutrifact entry, whereas the others will use all available label space to print data.
Data – this is where the user chooses between standard and simplified for the
Nutrifact information.
As always, touch the Enter key when finished making any changes.

COOL
Chapter 3: Configuration
Database
The COOL section of the Database cascade allows the user to change or apply specific
COOL parameters to a PLU. Selection of these categories prompts you for a number that
corresponds to database entries. Should you forget the number – or if there isn’t a COOL
entry for the PLU you’re using – you may also add a new COOL entry or edit an existing
one by following the menu prompts.
The buttons in this array are pretty self-explanatory, with each directing you to the COOL
sector of the same name. Type where necessary, use the database-given numbers
when you’re able and hit Enter when finished.
Accumulators
The Accumulator array allows the user to view and modify the accumulator settings.
