This unit
The HP/Agilent 3456A is a 6 1/2 digit digital multimeter engineered for precision measurement in calibration labs, R&D, and manufacturing environments. This microprocessor-based, fully guarded instrument delivers 100 nanovolts resolution at 48 readings per second and achieves ±0.0008% + 2 counts accuracy on the 10 V range over 24 hours at 23°C ±1°C. The 3456A combines high-speed burst capability - up to 330 readings per second - with ultra-low periodic measurement intervals down to one reading every fifteen minutes, making it equally suited to benchtop use and integration into automated test systems.

HP / Agilent 3456A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 3456A. 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 HP / Agilent 3456A 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.
