LED Annunciators
The 420HE display uses a set of six 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 and kg annunciators indicate the units associated with the displayed value: lb=pounds and
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 on page 2
shows which annunciators are used for all combinations of configured primary and secondary units.
