Scale Basic 4.2E Introduction
Introduction
Scale Basic in a programming language that is used to modify the functions of a weight
indicator. This makes it possible for the weight indicator to be customized to fit a wide variety
of weighing applications
The first section of this manual describes how to use EZ Link, a computer program that runs on
a PC computer under Microsoft’s ‘Windows’ operating system. EZ Link connects the indicator
to a PC computer. It is used to configure the weight indicator’s parameters and to enter Scale
Basic functions using the Windows graphical interface. Use the EZ Link section to learn how to
connect the indicator to a PC computer and how to use EZ Link to configure, program, and test
the weight indicator.
The Event Driven Programming section of the manual begins with a discussion of program
design and then goes on to describe event driven programming. Scale Basic functions are
controlled by a computer operating system called an “event driven executive”. This means that
the operation of the indicator is controlled by a combination of ‘events’ and ‘functions’. The
operating system scans for events. When an event is detected the operating system activates a
scale basic function.
The Scale Basic Tutorial section is a tutorial on the Scale Basic language. It is a step by step
demonstration on how to implement programs in Scale Basic.
The last section is a Reference on Scale basic. This section describes the Scale Basic
instructions, built in functions, condition codes, and event types.
