Normal Weighing Mode Operations

This section provides the operator with a description of front panel key functions and associated annunciators
(LEDs) used to operate the IQ 700 in the normal weighing mode.

After the unit is configured and calibrated, the unit is placed in the weighing or normal weighing mode (SW1-1
through SW1-4 open). In this mode, the weight indicator displays live weight data that is presently on the scale.

6.1

Display Test

The display check and EPROM verification are used to
test the indicator LED.

6.1.1

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.

6.1.2

EPROM Verification

Upon completion of the display check the software
version momentarily appears on the display. This value
indicates to the operator the current EPROM that has
been installed in the IQ 700. The IQ 700 operates with
an EPROM family group KDA 49.x (x is the version).

6.2

LED Annunciators

Table 6-1 shows the display panel annunciator and the
definitions of the annunciator.

6.3

Function Keys

Table 6-2 describes the various functions of the IQ 700
keys.

6.4

Gross/Tare/Net Weighing
Operations

In normal mode, the IQ 700 displays gross, tare, or net
weights using the LED annunciators to indicate scale
status and the type of weight value displayed.

6.4.1

Display Mode on Power Up

When the IQ 700 is initially powered up, the display
automatically appears in the gross mode.

6.4.2

ZERO Key Function

If the gross weight zero is within the zero band, press
the

ZERO

key. There are various things that would

make invalid zero conditions. They are:

Gross weight data above the defined zero band

Gross weight data in motion

Overload/underload condition

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

Table 6-1. Annunciator Definitions

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

NET

Selects the desired weight data to be viewed
(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
acquisition 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.
