6.0 Counting Operations
The 390HE 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.
