2.1 Basic counting principles
2 Introduction
The ZK810 is a counting scale indicator which, when attached to a BSQ digital scale
base, creates a 35,000 division counting system. The indicator, shown in
Figure 2.1
, is
easy to use. The indicator has an Ethernet port and two RS232 ports.
See the Specification literature for a full list of specifications.

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.
