6.0 Counting Operations
The IQ plus 390-DC provides a piece count mode that
allows the indicator to serve as a portable counting
scale. In piece count mode, the indicator display
shows the number of parts on the scale rather than the
weight of those parts.
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 enable operator access to piece count mode, set the
ACCESS parameter to ENABLE (COUNT submenu
on the PROGRM menu) or send the CNTMOD=
ENABLE EDP command.
Piece count mode has two submodes:
• Count display mode displays the current parts
count and allows ticket printing using the
CFMT print format.
• Sample acquisition mode is used to calibrate
the indicator for parts counting.
Count Display Mode
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.
If a sample weight has not yet been acquired, the
indicator switches automatically to sample acquisition
mode, described below.
Sample Acquisition Mode
Sample acquisition mode is used to select the sample
quantity and calibrate the indicator for the parts being
counted.
To set a new sample weight, do the following:
1. Place empty parts container on scale. Wait for
standstill, then press TARE to acquire the tare
weight of the container.
2. Press MODE to enter piece count mode.
3. From count display mode, 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 .
To view gross and net weight of parts, press MODE to
switch from count display mode to normal weighing
mode.
