This unit
The Advantest R6561 is a 6 1/2-digit digital multimeter engineered for precision DC voltage, micro-DC voltage, and resistance measurements in research and semiconductor applications. It delivers 10 nV sensitivity for micro-DC measurements and 1 μΩ resolution for resistance, supported by automatic offset cancellation and floating current source topology to eliminate thermal EMF and line resistance effects. Sampling rates reach 2,000 times per second with multi-sampling bulk output, enabling real-time data collection at 10 msec intervals in 6 1/2 digit mode.
Digital smoothing via moving average reduces noise without sacrificing measurement speed, while null function capability supports micro-resistance and offset voltage compensation.

Advantest R6561 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Advantest R6561. 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 R6561 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.
