Front Panel Keypad

Figure 1-1 shows the 120 keypad and LED annunciators.

The symbols shown under the keys (representing up, down, enter, left, right) describe the key functions assigned
in configuration and panel modes. In these modes, the keys are used to navigate through menus, select digits
within numeric values, and increment/decrement values. See Section 3.1.3 on page 8 for information about using
the front panel keys in configuration mode.

LED Annunciators

The 120 display uses a set of eight LED annunciators to provide additional information about the value being
displayed:

•

(gross) and

(net) annunciators are lit to show whether the displayed weight is a gross or net weight.

•

Center of zero (

): Gross weight is within ±0.25 graduations of zero. This annunciator lights when the

scale is zeroed.

•

Standstill (

): Scale is at standstill or within the specified motion band. Some operations, including

tare functions and printing, can only be done when the standstill symbol is shown.

•

lb, kg, oz,

and

annunciators indicate the units associated with the displayed value: lb=pounds,

kg=kilograms, oz=ounces, g=grams.

The displayed units can also be set to short tons (tn), metric tons (t), or NONE (no units information
displayed). The

and

LEDs function as primary and secondary units annunciators for some

combinations of primary and secondary units. If neither primary nor secondary units are lb, kg, oz, or g, the

annunciator is lit for primary units,

for secondary units.

Table 1-1 on page 3 shows which annunciators are used for all combinations of configured primary and
secondary units. For example:

•

If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the

LED is lit for primary

units,

for secondary units.

•

If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the

LED is lit for primary

units,

for secondary units. There is no LED for short tons, so the

LED is used as the secondary units

annunciator.

•

If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the

LED is lit for primary

units (tn), and

is lit for secondary units (lb). Because there is no LED for short tons, the

and

LEDs

are used as primary and secondary units annunciators.
