TABLE OF CONTENTS The manufacturers of digital measurement instruments equipped with the RS-232C interface driver usually provide their own (standard) computer programs designed to control data transmission from a measuring device to a computer and to data processing and presentation. The use of such a program makes the completion of a measurement system much easier, but it implies limitations resulting from the fact that the program does not fit individual measurement tasks. The elaboration of an original computer program to control measuring data transmission and data processing avoids such limitations. Programming is easier, since one of the generally used programming languages of visual (object) programming is applied. In high-level programming languages, such as Visual Basic or Delphi, there are procedures prepared for both serial transmission service in the RS-232C system and data processing. To illustrate the programming mode, in this section we discuss two examples of programs for controlling data transmission between a multimeter and a computer. These are the ScopeView program prepared by Metex Co., and an original Thermo program written by an author in Visual Basic. Metex Co. is a significant provider of digital devices for the instruments market, and therefore, the computer program may be useful to the users of Metex meters with the RS-232C interface.
The ScopeView program, supported by the Metex Corporation with the Metex meter of type M-4650CR, is presented next [1]. The program...
