This unit
The Advantest R6551 is a precision digital multimeter engineered for high-resolution measurement and automated test system integration. With a 5½ digit display (maximum reading 319999) and 3 ppm resolution, it delivers DC voltage, AC voltage (true RMS), resistance (two-wire and four-wire), DC current, AC current (true RMS), frequency, and continuity measurements across wide ranges. DC voltage measurements span 0.03 V to 1000 V with 1 µV minimum resolution.
AC voltage covers 300 mV to 700 V across 20 Hz to 300 kHz. Current measurements reach 3 A maximum on both DC and AC circuits with 1 µA resolution. Resistance measurements utilize a four-wire system across seven ranges from 300 Ω to 300 MΩ, minimizing cable resistance effects.

Advantest R6551 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Advantest R6551. 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 R6551 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.
