1.2 Operating Modes
The 480 has two modes of operation:
Weigh Mode
The indicator displays gross or net weights as required, using the annunciators
described in Section 1.3.2 on page 5 to indicate scale status and the type of weight
value displayed.
User Menu Setup Mode
The user menu setup mode is used to access the Accumulator Functions, Audit Trail,
display the Tare, Unit ID, Time & Date, Setpoints, Serial Communications
parameters, Print Formats, and view the Firmware Version.
It is accessible by pressing the MENU key on the front panel.
1.3 Front Panel Display
Figure 1-1 shows the 480 LED annunciators, keypad and key functions.
The symbols shown by the keys (representing up, down, enter, left, right) describe the key
functions assigned in the operating modes. The keys are used to navigate through
menus, select digits within numeric values, and increment/decrement values.

to unplug power.
The MENU key is used to access the User Setup menu.
Sets the current gross weight to zero, provided the amount of weight to be
removed or added is within the specified zero range and the scale is not in motion.
The zero band is defaulted to 2% of full scale, but can be configured for up to 100%
of full scale.
Switches the weight display to an alternate unit.
In numeric entry mode used as a “clear” key.
Sends “on-demand” print format out the serial port, provided the conditions for
standstill are met. PRINT may be displayed while the unit prints.
Performs one of several predetermined Tare functions dependent on the mode of
operation s. To view a stored tare, see Section 1.5.6 on page 9.
Also acts as an “enter” key for numeric or parameter entry.
Toggles the display between gross and net. If a tare value has been entered or
acquired, the net value is the gross weight minus the tare.
Gross mode is shown by the Gross/Brutto annunciator; net mode is shown by the
Net annunciator.
During a numeric entry, sets the currently select digit to 0, then selects one digit to
the right.

1.3.2 Annunciator Functions
The 480 display uses a set of eight LED annunciators to provide additional information
about the value being displayed.
See the 480 Legend Series Technical manual (PN 119201) for more information.
LED Description
Gross/Brutto LED
Gross weight display mode (or Brutto in OIML mode)
Net LED
Net weight display mode
Zero (Center of Zero) LED
The Center of Zero LED indicates that the current gross weight reading is within
+/- 0.25 display divisions of the acquired zero, or is within the center of zero band.
A display division is the resolution of the displayed weight value, or the smallest
incremental increase or decrease that can be displayed or printed.
Standstill LED
Scale is at standstill or within the specified motion band. Some operations,
including Zero, Tare and Printing, can only be done when the standstill LED is on.
lb/kg LED
Displays which unit of measure is being used.
lb and kg annunciators indicate the units associated with the displayed
value: lb = pounds, kg = kilograms.
The displayed units can also be set to short tons (tn), metric tons (t), ounces (oz),
grams (g), NONE (no units information displayed). The lb and kg LEDs function as
primary and secondary units annunciators. If neither primary nor secondary units
are lb or kg, the lb annunciator is lit for primary units and kg is lit for secondary
units.
T LED
Indicates that a push-button tare weight has been acquired and stored in memory.
PT LED
Indicates that a preset tare weight has been keyed in or entered and stored in
memory.
