The Advantest R6452A is a 5.5-digit digital multimeter engineered for R&D, manufacturing, and automated test systems. Its dual-channel architecture and dual display enable simultaneous independent measurement of two signals, creating a versatile measurement environment. Channel A delivers DC voltage, AC voltage, DC current, AC current, 2-wire resistance, low-power resistance, frequency, diode test, and continuity functions. Channel B provides DC voltage, DC current, and AC current measurement. A dedicated rear-panel input accepts Type K thermocouples with cold-junction compensation for temperature measurement.
