SMIQProgramming ExamplesDAnnex DD.1 Programming ExamplesThe examples explain the programming of the instrument and can serve as a basis to solve morecomplex programming tasks.QuickBASIC has been used as programming language. However, the programs can be translated intoother languages.1.

Initialization and Default StatusThe IEC bus as well as the settings of the instrument are brought into a defined default status at thebeginning of every program.
