LED Annunciators
The
320IS Plus
display uses eight LED annunciators to provide additional information about the value being
displayed (see Figure 1-1 on page 3):
Table 1-3 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
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 no 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.
See Section 3.2.2 on page 25 for more information about configuring primary and secondary display units.
LED Annunciators
Gross
The Gross and Net annunciators are lit to show whether the displayed weight is a
gross or net weight.
Net
Center of Zero
Gross weight is ±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.
The Tare Acquired light shows that a tare value has been entered.
Count
The Count annunciator is lit to show that the indicator is in piece count mode.
0 lb
lb and kg annunciators indicate the units associated with the displayed value:
lb=pounds, kg=kilograms. Two units of measurement can be chosen to toggle
between.
The displayed units can also be set to ounces (oz), short tons (tn), metric tons (t),
grams (g), or they can be disabled. A user-defined unit can also be set as secondary
unit by declaring a conversion factor in the setup menu. The lb and kg LED’s 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 lb
annunciator is lit for primary units, kg for secondary units.
