Normal Weighing Mode Operations

annunciators (LEDs) used to operate the IQ 700IS in
the normal weighing mode.
After the unit has been configured and calibrated, the
unit is then placed in the weighing or normal
weighing mode (SW 1-1 through SW 1-4 open). In
this mode, the weight indicator displays live weight
data that is presently on the scale.
5.1
Display Test
The display check and EPROM verification are used
to test the indicator LED.
5.1.1
Display Check
Observe the display when power is first applied to the
indicator. All six indicator LEDs (Zero, Net, Gross, lb,
kg, and Motion) should be turned on and each seven
segment display, with its associated decimal point,
will advance across the display field, allowing the
operator to check for any missing segments or decimal
points.
5.1.2
EPROM Verification
Upon completion of the display check an EP. 49.x
momentarily appears on the display. This value
indicates to the operator the current EPROM that has
been installed in the IQ 700IS. The IQ 700IS operates
with an EPROM family group KDA 49.x (x is the
version).
5.2
LED Annunciators
Table 5-1 shows the display panel annunciator and the
definitions of the annunciator.
Annunciator
Annunciator Definition
ZERO
On when gross weight data is within ±1/4
graduation of the center of zero
NET
On when indicator is in net weighing mode
GROSS
On when indicator is in gross weighing mode
lb/kg
Shows units of displayed weight data
MOTION
On when display data is changing by the
number of graduations selected in Parameter 9
in configuration mode

Function Keys
Table 5-2 describes the various functions of the IQ
700IS keys.
Key
Functional Description
ZERO
Rezeroes scale if the gross weight is within the
band of zero selected in the configuration
mode (1.9% or full scale)
GROSS
Selects the desired weight data to be viewed
NET
(GROSS or NET). The gross and net LED
annunciators indicate which display mode is
active.
TARE
When used in the gross mode, the indicator
will acquire the tare value and automatically
shift to the net display mode. If a tare
acquisiton is negative or the weight data is in
motion, the indicator remains in the present
mode and no tare is performed.
UNIT
If the indicator is set up to perform lb/kg
conversion, this key toggles weight data
between its calibrated base weight unit in lb to
kg units. The lb and kg annunciator LEDs
indicate which units are displayed.
PRINT
Issues a demand print command to the serial
output.

5.4
Gross/Tare/Net Weighing
Operations
In normal mode, the IQ 700IS displays gross, tare, or
net weights using the LED annunciators to indicate
scale status and the type of weight value displayed.
5.4.1
Display Mode on Power Up
When the IQ 700IS is initially powered up, the display
automatically appears in the gross mode.
5.4.2
ZERO Key Function
If the gross weight zero is within the zero band, press
the zero key. The following conditions make invalid
zero conditions:
• Gross weight data above the defined zero band
• Gross weight data in motion
• Overload/underload condition
