The Solartron 7150 Digital Multimeter is suitable for general-purpose bench applications and for systems use. It performs all common measurement functions and has a scale length in excess of 200000. The Multimeter has a built-in GP-IB Systems Interface port which conforms with the internationally-recognised IEEE 488 (1978) standard, thus ensuring the compatibility of the 7150 with a wide range of system devices produced both by Solartron and by other manufacturers. The front panel controls permit all main functions to be selected or changed. Additional facilities become available when the 7150 is controlled remotely via the GP-IB Interface port.
