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.
