Applies to an interface system used to interconnect both programmable and non-programmable electronic measuring apparatus and accessories. Specifies device-independent requirements which need to be met in order to interconnect and communicate unambiguously. Permits apparatus with a wide range of capabilities to be connected to the system. Enables the interconnection of independently manufactured apparatus into a single functional system.
