This unit
The HP/Agilent 3457A is a high-resolution digital multimeter engineered for precision measurement in benchtop and system-integrated environments. It delivers 3½ to 6½ digits of resolution, extendable to 7½ digits, with exceptional DC voltage accuracy of 5 ppm over 90 days. The instrument provides flexible reading rates from 1 reading every 2 seconds to 1350 readings/second at 3½ digits, making it suitable for both slow analog measurements and high-speed data acquisition.
Technical Specifications DC Voltage: 30 mV to 300 V range with 10 nV sensitivity. Accuracy spans 0.0017% + 6 counts at 3 V to 0.005% + 6 counts at 300 V (90-day calibration cycle). Input resistance reaches 10 GΩ on ranges to 3 V, dropping to 10 MΩ ± 1% on higher ranges. AC Voltage: 1 MHz true RMS bandwidth across 30 mV to 300 V. Best accuracy of 0.13% + 0.116 counts from 100 Hz to 20 kHz. Input impedance is 1 MΩ ± 1% with less than 90 pF shunt capacitance. Current Measurement: DC ranges from 300 µA to 1 A with input resistance values 0.1 Ω to 1000 Ω. AC current operates on 30 mA, 300 mA, and 1 A ranges with accuracies of 0.25% + 290 counts and 0.35% + 290 counts respectively. Resistance: 2-wire and 4-wire configurations spanning 30 Ω to 3 GΩ. Best accuracy is 0.0035% + 6 counts at 3 kΩ and 30 kΩ ranges. Sensitivity extends from 10 µΩ to 1 kΩ. Frequency: Voltage input from 10 Hz to 1.5 MHz; current input from 10 Hz to 100 kHz.

HP / Agilent 3457A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 3457A. 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 3457A 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.
