Uni-trend High-precision Fully Automatic Intelligent Digital Multimeter UT890D+
Introducing the UNI-T UT890D+, a cutting-edge True RMS digital multimeter from the advanced UT890 series, engineered for unparalleled accuracy and user safety. This 6000-count, manual-ranging device goes beyond standard measurements, incorporating intelligent alert systems such as an automatic fuse blow alarm and comprehensive overvoltage/overcurrent warnings. These features not only notify users of potential overloads but also ensure the correct installation and functionality of fuses, enhancing operational safety and protecting the instrument.
The UT890D+ is equipped for versatile frequency measurements, capable of handling both low-voltage signals (10Hz to 10MHz below 30V) and high-voltage applications (10Hz to 10kHz from 5V to 750V). This specialized capability is crucial for precise power frequency analysis in various electrical systems. A standout innovation is its exclusive LIVE single-lead live wire detection, allowing electricians and technicians to swiftly and safely identify live and neutral conductors using just one test lead, streamlining diagnostics and improving workflow efficiency. While the UT890C offers high-precision temperature measurement, the UT890D+ excels with its dedicated live wire detection functionality, making it an indispensable tool for electrical professionals.
Advanced Features of the UT890 Series
- Audible fuse blow alert system
- True RMS for accurate AC voltage and current readings (up to 1000V AC/DC, 20A AC/DC)
- Non-Contact Voltage (NCV) detection with continuity buzzer and light alarm
- Rapid charging measurement for large capacitors up to 100mF
- Convenient AC/DC current mode memory function
- Unique single-lead live wire detection (specific to UT890D+)
- Dual-range frequency measurement for power frequencies (low-voltage and high-voltage)
The UT890D+ Digital Multimeter: Precision Meets Protection
The UNI-T UT890D+ is a professional-grade digital multimeter distinguished by its robust feature set and a design philosophy centered on safety. Its True RMS capability guarantees precise measurements even with distorted, non-sinusoidal waveforms prevalent in modern electronics. The integrated fuse blow alarm, coupled with overvoltage and overcurrent warnings, fortifies user safety by proactively alerting to hazardous conditions and verifying the instrument's operational integrity.
Specialized Frequency Measurement for Electrical Systems
Differentiating itself from conventional multimeters, the UT890D+ provides refined frequency measurement options. It adeptly measures low-voltage frequencies ranging from 10Hz to 10MHz (for inputs under 30V) and high-voltage frequencies from 10Hz to 10kHz (for signals between 5V and 750V). This comprehensive frequency analysis makes it an invaluable asset for diagnosing and maintaining intricate power systems, both industrial and residential.
Effortless Live Wire Identification with Single-Lead Technology
A key innovation of the UT890D+ is its LIVE single-lead live wire detection. This intelligent function empowers users to quickly and securely differentiate live conductors from neutral ones with minimal effort, requiring only a single test lead. This capability significantly reduces diagnostic time and elevates safety protocols during electrical installation and troubleshooting tasks.
Built for Safety and Intuitive Operation
The UT890D+ is meticulously crafted for user safety and ease of use. It features clear audible and visual alarms for NCV and continuity tests, alongside a generous 63x37mm LCD with a bright backlight for optimal readability in diverse lighting environments. An automatic power-off function helps conserve battery life. Adhering to stringent safety standards, it carries a CAT II 1000V / CAT III 600V rating, ensuring dependable performance across a broad spectrum of electrical applications.
