Uni-T UT201R Digital Clamp Meter

The Uni-T UT201R Digital Clamp Meter is a professional-grade instrument designed for precise electrical measurements in both residential and industrial environments. This versatile device allows for non-invasive current measurement, enabling technicians to troubleshoot circuits efficiently without interrupting the power flow. Its robust construction and ergonomic interface make it a reliable companion for daily electrical maintenance and diagnostic tasks.

Advantages

The primary benefit of the Uni-T UT201R is its ability to perform accurate AC current measurements up to 400 A using its integrated clamp, which simplifies testing in tight spaces. The inclusion of True RMS technology ensures that measurements remain accurate even when dealing with non-sinusoidal waveforms. Furthermore, the device offers a comprehensive suite of functions including voltage testing, resistance measurement, and continuity checks, all presented on a clear, backlit LCD screen for optimal visibility in low-light conditions.

Suitable for

• Measuring AC current in electrical panels and wiring
• Troubleshooting household and industrial electrical circuits
• Checking voltage levels in AC and DC systems
• Verifying electrical continuity and diode functionality
• Non-contact voltage detection for safety inspections

When it may not be suitable

This device is not designed for measuring high-voltage industrial power grids exceeding its safety rating of CAT II 600V or CAT III 300V. It is also not intended for measuring DC current, as the clamp mechanism is specifically calibrated for AC current applications.

Key specifications

• AC Current range: up to 400 A
• AC/DC Voltage range: up to 600 V
• Resistance measurement: up to 40 MΩ
• Jaw opening capacity: 28 mm
• Safety ratings: CAT II 600V, CAT III 300V
• Additional features: True RMS, NCV, Data Hold, Max/Min, Auto power off

How to use

To use the Uni-T UT201R, first ensure the batteries are correctly installed. Select the desired measurement function using the rotary dial. For current measurements, open the clamp jaws and enclose a single conductor, ensuring the jaws are fully closed. For voltage or resistance, connect the provided test leads to the input terminals and touch the probes to the test points. Use the Data Hold or Max/Min buttons to capture specific readings as needed.

What to consider before purchase

• Verify that the current range meets your specific project requirements
• Ensure the safety category matches your intended work environment
• Confirm that you do not require DC current measurement capabilities
• Check that the jaw size is sufficient for the diameter of the cables you intend to test

Usage recommendations: Always inspect the test leads for damage before use and ensure the device is set to the correct measurement range to prevent damage to the internal circuitry. Keep the device clean and store it in a dry environment when not in use.
