1.2 Operating Modes
The 480 has two modes of operation:
Normal (Primary) Weigh Mode
Normal mode is the default mode of the indicator. 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.

1.3.1 Key Functions
See the 480 Legend Series Technical manual (PN 119201) for more information.
Key Function
Turns the unit on/off.
If power mode is set to manual, the POWER button must be
used to turn the unit on and off. If power mode is set to
auto, the unit will automatically power on when it’s plugged
in and the only way to turn it off is 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.
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.
