1.2 Front Panel Display
Figure 1-1 shows the 520 front panel keys and the key
functions assigned in normal mode.
The 520 display is divided into three areas (see
Figure 1-2):
• The primary display consists of seven large,
14-segment digits used to display weight data.
• A two-digit annunciator shows the units
associated with the displayed value: lb=pounds,
kg=kilograms, oz=ounces, T=short tons, t=metric
tons, LT=long tons, g=grams, GN=grains. The
units can also be set to NONE (no units
information displayed).
The 16-digit secondary display is used to display the
weighing mode (Gross/Brutto or Net), status
indicators, including standstill (
) and center of
zero ( ), Bar Graph and Checkweigh.
The symbols shown over the keys in Figure 1-1
(representing up, down, enter, left, right) describe the
key functions assigned in setup mode. In setup mode,
the keys are used to navigate through menus, select
digits within numeric values, and increment/decrement
values. See Section 3.1.3 on page 18 for information
about using the front panel keys in setup mode. In
count mode, the displayed value is PC (Piece Count).
