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.
