This unit
The Keysight E2378A is a rugged handheld multimeter engineered for field service, maintenance, and industrial troubleshooting in demanding environments. This 3.5-digit instrument delivers precision measurements across DC/AC voltage, current, resistance, continuity, and diode testing with a 3200-count digital display paired with a 32-segment analog bar graph. Auto-ranging and manual hold modes accommodate diverse measurement scenarios, while an audible continuity beep and data hold function enhance workflow efficiency.
Built for durability, the meter features overvoltage protection to 1000 V, splash-resistant construction, and extended battery life for extended field operations. A one-year calibration cycle supports metrological compliance in professional service environments.

Keysight / Agilent E2378A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keysight / Agilent E2378A. 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 E2378A 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.
