1.3.2 LED Annunicators
The 420 display uses a set of six LED annunicators 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 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), or NONE (no
units information displayed). The
lb and kg LEDs function as primary and secondary units annunciators for
some combinations of primary and secondary units. If neither primary nor secondary units are lb or kg the lb
annunciator is lit for primary units, kg for secondary units.
Table 1-1 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 lb LED is lit for primary
units, kg for secondary units.
• If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the lb LED is lit for primary
units, kg for secondary units. There is not an LED for short tons, so the kg LED is used as the secondary
units annunciator.
• If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the lb LED is lit for primary units
(tn), and kg is lit for secondary units (lb). Because there is no LED for short tons, the lb and kg LEDs are
used as primary and secondary units annunciators.
