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
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
.
