This Operator Card describes the IQ plus 390-DC LCD display, weighing and counting operations, and
procedures for battery replacement and AC adapter use.
LCD Display and Annunciators
The IQ plus 390-DC display uses a set of LCD
annunciators to provide additional information about
the value being displayed. The illustration below
shows these annunciators and their meanings.
G
The displayed weight is a gross weight.
N
The displayed weight is a net weight.
Scale is at standstill or within the specified motion
band. Some operations, including zero, tare, and
printing functions, can only be done when the
standstill symbol is shown.
Center of zero. Gross weight is within 0.25
graduations of zero. This annunciator lights when
the scale is zeroed.
Indicates that a tare has been entered. The tare
value can be entered by pressing the
TARE
key on
the keypad or by sending the KTARE EDP
command.
Indicates that the battery charge is low.
lb, kg, PC
Three arrow annunciators on the right side of the
LCD display indicate the units associated with the
displayed value. The bottom arrow annunciator
(PC) is lit when the indicator is in piece count
mode. The top and middle arrows, labeled lb and
kg, show primary and secondary units, as
described below:
•If the displayed weight is in pounds, the top
arrow (lb) is lit; if kilograms, the middle
arrow (kg) is lit.
•If the primary unit of weight is pounds, the
middle (kg) arrow is lit for secondary units—
or, if the primary unit is kilograms, the top
(lb) arrow is lit for secondary units, unless the
secondary unit of weight is the same as the
primary unit.
•If neither primary nor secondary units are
pounds or kilograms, the top arrow is used as
a primary units annunciator and the middle
arrow is used as the secondary units
annunciator.
A set of replacement overlay decals is included in
the parts kit for units other than pounds and
kilograms.

Counting Operations
The illustration below shows the IQ plus 390-DC keypad and piece count mode key functions.
NOTE: Legal-for-trade applications require product to be sold by weight rather than an equivalent parts
count. Operator access to piece count mode is disabled when the indicator is shipped from the factory. To
use piece count mode, access must be enabled when the indicator is configured.
Piece count mode is entered by pressing the
MODE
( GROSS/NET ) key from normal weighing mode. In
count display mode, the display shows the number of
parts rather than weight, the arrow annunciator at the
right side of the LCD display points to piece count
(PC), and pressing the
PRINT
key sends the CFMT
print format data string to the serial port.
IQ plus 390-DC counting operations are summarized
below:
Acquire Parts Sample
1. Place empty parts container on scale. Wait for
the standstill annunciator ( ), then press
TARE
to acquire the tare weight of the
container.
2. Press
MODE
to enter piece count mode.
3. Press the
SAMPLE
(
UNITS
) key to enter
sample acquisition mode.
4. The indicator display shows the message
Addnnn
, where
nnn
is the sample quantity to
be placed on the scale. Add the number of
parts shown or choose a different sample size
by pressing the
SAMPLE
key to scroll through
the selectable sample quantities (5, 10, 20, 50,
100).
5. Once the sample quantity is on the scale,
press
ENTER
to calibrate the indicator for
counting the new parts. The indicator display
shows the message
–CNT–
as it acquires the
sample weight, then switches to count display
mode and shows the part quantity.
If the weight of the sample quantity is insufficient
for piece counting, the indicator automatically
requests the next higher sample quantity by
showing the
Addnnn
message again. If the sample
quantity is at maximum (100) and the sample
weight is still not sufficient, the indicator shows
the message
CNTERR
.
Display Part Weight
To view gross and net weight of parts, press
MODE
to switch from count display mode to
normal weighing mode.

indicator adapter port.
The IQ plus 390-DC enclosure cannot
be rated for NEMA 4X/IP66 applications
with the AC adapter port cover open.
Do not use the AC adapter in washdown environments.
Figure 2. AC Adapter Port Cover
When not using the AC adapter, close the adapter port
cover and reinstall all backplate screws. Use the
torque pattern shown in Figure 3 to prevent distorting
the backplate gasket. Torque screws to 15 in-lb (1.7
N-m).
