This unit
The Advantest R6581T is an 8.5-digit digital multimeter engineered for high-precision DC measurements in laboratory, development, and quality control environments. This DC-only instrument delivers exceptional accuracy across DC voltage, DC current, and resistance measurements - both 2-wire and 4-wire configurations. The R6581T combines stability with resolution to support demanding metrology and component characterization workflows where measurement uncertainty must be tightly controlled.

Advantest R6581T — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Advantest R6581T. Calibration covers DC voltage accuracy at all ranges, AC voltage (True RMS) accuracy at 50 Hz, 1 kHz, and 10 kHz, DC current accuracy, resistance accuracy at all decade ranges, frequency accuracy, and diode test voltage. Fluke 87V and 289 also include capacitance and temperature calibration.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Advantest R6581T 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.
