This unit
The Keysight U3402A is a 5½ digit dual-display digital multimeter engineered for fundamental DC, AC, and AC+DC voltage and current measurements up to 750 V and 12 A respectively. This benchtop instrument delivers 120,000-count resolution with basic DC voltage accuracy to 0.012%, supporting both 2-wire and 4-wire resistance measurement to 300 Ω. Beyond standard functions, it integrates frequency analysis, continuity testing, and diode characterization with selectable measurement speeds (Slow, Medium, Fast) to balance resolution against acquisition rate.
The bright VFD dual display enables simultaneous parameter viewing, streamlining troubleshooting workflows. On-board math functions include dBm, Relative (REL), Min/Max logging, Compare, Hold, and Percentage calculations. A Kensington lock slot provides physical security for laboratory and field environments.
RS232 connectivity is available for calibration purposes. The multimeter ships with a test lead set and is specified for indoor operation in low-condensation areas.

Keysight / Agilent U3402A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keysight / Agilent U3402A. Calibration covers DC voltage accuracy at all ranges, AC voltage (True RMS) accuracy at 50 Hz, 1 kHz, and 10 kHz, DC current accuracy, resistance accuracy at all decade ranges, frequency accuracy, and diode test voltage. Fluke 87V and 289 also include capacitance and temperature calibration.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Keysight / Agilent U3402A faults: blown input fuse, worn input jacks, display segment failure, relay contact wear on bench DMMs. Common faults include worn input jacks (banana socket contact wear on the mA and COM terminals), blown input fuses (especially the 440 mA HRC fuse), and display segment failures. Keithley 2000/2001/2002 bench DMMs commonly develop relay contact wear affecting resistance accuracy after extended service.
Keysight / Agilent U3402A price
This Keysight / Agilent U3402A is listed at $650. Calibration is available separately from $450. Contact us for volume pricing or if you need multiple units.
Keysight / Agilent U3402A calibration cost
NIST-traceable calibration for the Keysight / Agilent U3402A is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers DC voltage accuracy at all ranges, AC voltage (True RMS) accuracy at 50 Hz, 1 kHz, and 10 kHz, DC current accuracy, resistance accuracy at all decade ranges, frequency accuracy, and diode test voltage. Fluke 87V and 289 also include capacitance and temperature calibration.. Turnaround is 1 to 3 business days after receipt. See full calibration details →
