Digital Multimeter UNI-T UT161B 1000V True RMS

Intelligent Connectivity and Precision Electrical Auditing

The UNI-T UT161B represents the advanced standard for professional electrical diagnostics and electronic troubleshooting, specifically engineered for the high-reliability monitoring of industrial and commercial power systems. In the South African telecommunications, renewable energy, and facility management sectors—where auditing power quality over time or identifying subtle voltage anomalies in switching power supplies is critical—the UT161B provides a robust 6,000-count resolution. By integrating True RMS accuracy with USB data communication, this instrument serves as a primary diagnostic workstation for senior technicians and electrical engineers.

Professional Accuracy and Smart System Versatility

The UT161B is optimized for high-fidelity data capture across diverse technical platforms:

• True RMS & 1000V AC/DC Capacity: Essential for obtaining accurate readings on non-sinusoidal waveforms found in modern VFDs and electronic ballasts, while maintaining a safe 1000V ceiling for high-energy industrial applications.

• Intelligent USB Data Logging: Features an optical-to-USB interface that allows for safe, isolated data transmission to a PC. This enables real-time monitoring and the generation of detailed digital audit logs, essential for identifying intermittent faults.

• Broad Frequency and Duty Cycle Range: Capable of measuring frequency up to 10MHz, making it an indispensable tool for troubleshooting digital timing circuits, signal generators, and industrial control systems.

Intelligent Auditing and Field Performance

Efficiency and data integrity are built into the core functionality of the UT161B:

• Large Backlit LCD with Analog Bar Graph: Features a high-speed analog bar graph for rapid visual tracking of fluctuating signals, complemented by a large backlit display for error-free data interpretation in low-light environments.

• Audible & Visual Mis-plug Alarm: A critical safety feature that provides both sound and light warnings if test leads are connected to the wrong terminals for the selected function, preventing potential instrument damage.

• Comprehensive Component Testing: Beyond standard voltage, the UT161B provides high-precision testing for capacitance (up to 60mF), resistance, and diodes, allowing for the rapid diagnosis of faulty electronic components.

Industrial Ergonomics and Safety Reliability

Housed in a ruggedized, double-injection chassis, the UT161B is built for the rigors of the field. The meter is fully compliant with CAT III 1000V / CAT IV 600V safety standards, ensuring the highest level of operator protection during high-energy circuit testing. With its tactile selector dial and integrated probe holders, the UT161B delivers a seamless, professional operational experience for the modern technician.

Professional Application Scenarios

• Telecommunications Maintenance: Troubleshooting DC power rails and using USB logging to audit signal stability in server environments.

• Industrial Electrical Auditing: Identifying phase imbalances and auditing current draw in high-voltage distribution boards.

• Electronic R&D and Bench Testing: Precise voltage rail monitoring and frequency analysis in complex PCB assemblies.

• Facility Preventive Maintenance: Conducting routine load checks on industrial power circuits and monitoring for long-term voltage drift.

• Renewable Energy Infrastructure: Verifying high-voltage DC outputs in solar arrays and auditing inverter terminal connections.

Maintenance and Best Practices

• Optical USB Safety: Always use the provided optical-to-USB cable to ensure the meter remains electrically isolated from the PC during high-voltage data logging.

• Terminal Safety: Pay attention to the audible/visual mis-plug alarm; if the meter beeps, double-check your lead configuration before applying power.

• Lead Integrity: Periodically inspect the high-quality test leads for insulation wear to ensure stable, low-resistance connections in high-resolution modes.

• Battery Care: Replace the batteries as soon as the low-power indicator appears to ensure the True RMS processor and USB module maintain peak performance.
