Agilent/Keysight 34530A

The Agilent/Keysight 34530A is a high-performance digital multimeter delivering exceptional accuracy and resolution across a comprehensive range of electrical measurements. Built for precision work in R&D, manufacturing, and service environments, it measures DC and AC voltage, current, resistance (2-wire and 4-wire), frequency, period, capacitance, and temperature with true RMS capability on AC signals. The instrument combines 6½-digit resolution with measurement speeds up to 50,000 readings/sec and integrates advanced triggering, data logging, and real-time statistical analysis.

Accuracy (1 Year Calibration)
DC Voltage ranges from 100 mV to 100 V with accuracy to ±(0.0015% to 0.0030% of reading + 0.0004% to 0.0006% of range). AC Voltage (true RMS) maintains ±(0.02% to 0.05% of reading + 0.02% to 0.04% of range) across 100 mV to 750 V spans. Resistance accuracy reaches ±(0.002% to 0.007% of reading + 0.0005% to 0.001% of range). DC Current provides ±(0.002% to 0.007% of reading + 0.0005% to 0.006% of range); AC Current (true RMS) ±(0.015% to 0.10% of reading + 0.004% to 0.006% of range). Frequency/Period accuracy is ±(0.006% of reading + 0.000% of range). Capacitance at 1.0000 nF range: ±(0.005% of reading + 0.003% of range). Temperature measurement via RTD (-200 °C to 600 °C) achieves ±0.06 °C; thermistor (-80 °C to 150 °C) ±0.08 °C.

Resolution & Speed
Up to 6½ digits with DC and AC current resolution to 100 pA on 100 µA ranges. Data acquisition speeds reach 50,000 readings/sec at 4½ digits, 10,000 readings/sec at 5½ digits, and 1,000 readings/sec at 6½ digits.

Memory & Capture
1 million readings volatile memory; 50,000 readings non-volatile (Data Logger). Peak-detect captures transients as short as 20 µs.
