This unit

The Advantest R6581 is a precision digital multimeter engineered for high-accuracy measurement across DC and AC domains. It delivers 8.5-digit resolution with True RMS AC capabilities, making it suitable for electronics testing, maintenance, and calibration work. The instrument covers DC voltage (100 mV to 1000 V), DC current (100 nA to 1 A), 2-wire and 4-wire resistance, frequency, and temperature measurements.


Its exceptional DC voltage accuracy - as low as 5 ppm + 0.2 ppm on the 10 V range - and sophisticated 4-wire resistance measurement with selectable source current modes (10 mA down to 100 nA) enable precision characterization of components and circuits. The R6581 incorporates automatic thermoelectromotive force cancellation in resistance mode and achieves low noise performance across all measurement functions at NPLC100 integration.

Common Advantest R6581 faults: blown input fuse, worn input jacks, display segment failure, relay contact wear on bench DMMs. Common faults include worn input jacks (banana socket contact wear on the mA and COM terminals), blown input fuses (especially the 440 mA HRC fuse), and display segment failures. Keithley 2000/2001/2002 bench DMMs commonly develop relay contact wear affecting resistance accuracy after extended service.
