34410 A Multimeter

The Keysight 34410A is a 6½-digit digital multimeter (DMM) manufactured by Keysight Technologies, previously sold under the Agilent Technologies brand. The 34410A is a high-performance instrument designed for both benchtop and automated system use. The multimeter supports DC voltage, AC voltage, DC current, AC current, 2-wire and 4-wire resistance, frequency, period, capacitance, temperature, continuity, and diode test measurements.^[2][3][1][4]

The 34410A is part of Keysight's family of 6½-digit multimeters that succeeded the industry-standard 34401A. The instrument offers expanded measurement ranges, including DC and AC current ranges down to 100 μA with 100 pA resolution. A peak-detect capability allows capture of peaks as short as 20 μs.^[1]

The 34410A uses an integrating analog-to-digital converter architecture to achieve high resolution and noise rejection. The AC voltage measurement function employs a digital measurement technique that improves accuracy across a wide frequency range. The instrument provides auto-ranging, null, and math functions including statistics and limit testing.^[1][2]

The 34410A features a dual display on the front panel, showing both a primary measurement reading and a secondary parameter such as frequency or additional measurement context. The instrument includes a data logger function that can store up to 50,000 readings in non-volatile memory for unattended measurement sessions. Remote connectivity is provided via LAN, USB, and GPIB interfaces, all standard on the instrument.^[1][2][3]

The 34410A is used for precision DC and AC voltage and current measurements, resistance, frequency, and period measurements in electronics design, production test, calibration, and education. The inclusion of capacitance and temperature measurement capabilities extends the instrument's utility beyond traditional digital multimeter functions. The instrument is suitable for both benchtop laboratory use and rack-mounted system integration.^[1][4]
