2.1 Basic counting principles
2 Introduction
The ZK830 is an indicator which, when attached to a BSQ digital scale base, creates a
highly accurate counting, weighing and checkweighing system. The indicator, shown in
with the optional keypad, is easy to use. The indicator has two full duplex
RS232 ports, one USB VCP (virtual comm port), Ethernet port, three logic level inputs
with configurable functions, three setpoint outputs and an expansion card slot for 1 of
2 option cards:
l
802 Wireless card
l
5V Analog scale card
Other options available are a stack light kit for visual confirmation of outputs, two
columns for mounting the indicator above the BSQ base, battery packs and scanners.
See the Specification literature for a full list of specifications.

The ZK830 can have a remote base attached which can be analog or digital.
For information on the BSQ bases please refer to the manuals for BSQ line.
2.1 Basic counting principles
There are several things which affect counting accuracy:
l
environmental noise (vibration, wind, etc.)
l
number of sample parts used
l
the weight consistency of the sample parts
l
the weight of one part
l
accuracy requirement
Changes in each, or any one, of these variables can affect the accuracy for the better
or for the worse. If there is wind or vibration accuracy will drop, especially if parts are
small in weight. If parts are not a consistent weight, accuracy can be poorer but may
be increased by using a large sample size.
Accuracy with this system can be extremely high, even with small parts, if the
environment is controlled, parts have a consistent weight and a large enough sample
size is used.
