Typical Applications Automated test and measurement systems requiring precision resistance insertion, equipment calibration platforms, potential divider configurations, and remote resistance control in laboratory or production environments.

Compatibility & Integration Standard 24-pin IEEE-488 connector. Commands transmitted in Ohms (direct mode) or hexadecimal format (divider mode) with carriage return or line-feed terminator. Supports local/remote mode switching and command execution on G.E.T. trigger. Operates best in dust-free, temperature-stable environments with shielding from direct sunlight and thermal EMF sources.
