The HIOKI RM3545A-2 precision resistance meter measures low-resistance welds, connectors and conductors for development and production inspection. Four-terminal measurement, offset compensation and contact checking help distinguish small resistance changes.
Model configuration: RM3545A-2 accepts up to two optional Z3003 units, giving up to 20 four-wire channels. Multiplexer units are not included.
Configuration: The L2101 clip type lead is included only in the Kit version. Multiplexer units and external switch mainframes are sold separately.
Contact RCC Electronics for configuration assistance and Canadian application support.
Instrument specifications apply under HIOKI's stated measurement conditions. Kit contents are listed separately.
