UNI-T UT71E Intelligent Digital Multimeters

UNI-T UT71E Intelligent Digital Multimeters

The UNI-T UT71E is the flagship model in the UT71 series of intelligent digital multimeters, marrying precision measurement with advanced usability. Housed in a robust, ergonomically contoured case, the UT71E offers a generous 4¾-digit main display and dual 4,000-count secondary displays, ensuring that readings remain crisp and legible even in low-light or fast-changing conditions. A variable backlight can be toggled between two brightness levels or set to switch off automatically, balancing visibility with battery conservation .

Internally, the UT71E employs true RMS circuitry across its voltage and current ranges, affording accurate readings on both sinusoidal and distorted waveforms. This accuracy is complemented by an intelligent limit-setting function: users can define upper and lower thresholds, and the meter will audibly and visually alert whenever measurements stray beyond these bounds—an invaluable safeguard during mass-production testing or system commissioning . Under the hood, a high-speed microprocessor orchestrates auto-ranging, peak-hold capture, and a fast-responding analog bar-graph, delivering both detailed readouts and an intuitive, real-time sense of signal behavior.

. Power management is similarly polished: the meter will automatically shut off after an idle interval (customizable via its setup menu), and a low-battery icon prompts timely replacement of its single 9 V battery.

Physically, the UT71E is designed for both bench and field use. Rated CAT III 1000 V and CAT IV 600 V, it is built to withstand the demands of industrial environments. A knurled rotary switch, tactically separated function buttons, and a rigid tilt-stand combine to make measurements both rapid and comfortable. In the UT71E, UNI-T has crafted a tool that transcends basic electrical measurement—delivering intelligent, connected, and reliable performance for today’s complex testing needs.

Features:

• True RMS measurement with high display count: Ensures accurate AC readings even on non-sinusoidal waveforms, dual 4,000-count secondary displays for maximum resolution and clarity.
• Mis-plug alarm: Audible and visual warning if test leads are inserted into incorrect terminals, helping prevent measurement errors and instrument damage.
• MAX/MIN/REL modes: Built-in functions to capture maximum, minimum, or relative (delta) values over time, with audible alerts when readings exceed predefined thresholds.
• Selectable Auto or Manual ranging: Automatically selects the optimal measurement range for ease of use, or lets you lock in a fixed range when needed for more stable readings.
• Data logging: Internal memory stores up to 100 readings (UT71E), which can be recalled on-device or sent via USB to the UNI-T Smart Measure App for analysis and reporting.
• Auto power-off & backlight: Conserves battery life by automatically shutting down after a user-defined idle period and by switching the display backlight off after a set timeout, backlight can also be manually toggled between two brightness levels.
