The Keysight 34461A is a 6½ digit digital multimeter engineered for precise measurements across DC/AC voltage, current, resistance, frequency, and specialized functions. Built on Truevolt technology, this instrument eliminates real-world measurement errors—noise, input bias current, and injected current—delivering 35 ppm basic DCV accuracy (0.0035%) and true RMS AC measurements with crest factor support up to 10.
Measurement capabilities span DCV to 1000 V, ACV to 750 V, DC/AC current from 100 µA to 10 A, 2- and 4-wire resistance from 100 Ω to 100 MΩ, frequency and period from 3 Hz to 300 kHz, capacitance, diode testing, continuity, and temperature via RTD/PT100 and thermistor sensors. The 4.3-inch color graphical display supports number, histogram, bar chart, and trend chart modes, enabling real-time data visualization. Internal memory stores 10,000 readings with data logging for trend analysis and digitizing mode for transient capture.
