This unit
The Advantest R6451A is a 5.5-digit digital multimeter engineered for general-purpose electrical measurement across R&D, production, and field environments. This Japanese-manufactured instrument delivers true RMS AC measurements, frequency analysis, and resistance testing with 180 ppm + 5 digits accuracy on DC voltage and ±0.1% ± 6 digits on the 200 mΩ resistance range. The half-width 19" 2U form factor accommodates both benchtop and rack-mount deployment.

Advantest R6451A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Advantest R6451A. 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 R6451A 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.
