6 320IS Installation Manual
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 3.3.2 on page 24 for more information about configuring primary and secondary display units.
1.6 Indicator Operations
Basic
320IS
operations are summarized below.
1.6.1 Toggle Gross/Net Mode
Press the
GROSS/NET
key to switch the display mode from gross to net, or from net to gross. If a tare value has been
entered or acquired, the net value is the gross weight minus the tare. The
Tare
( ) annunciator is lit when a tare
value is currently stored in memory.
1.6.2 Toggle Units
Press the
UNITS
key to switch between primary and secondary units. The appropriate units LED to the right of the
display is lit.
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.
