UNI-T UT256 Fork Current Meter, DC/AC Current up to 60A, True-RMS, NCV

The UNI-T UT256 is a professional-grade fork current meter engineered for precise DC and AC current measurements up to 60A. Designed with True-RMS technology, this device ensures accurate readings even when dealing with non-sinusoidal waveforms. Its slim, ergonomic fork design allows for effortless access to cables in confined spaces, making it an essential tool for electrical maintenance, troubleshooting, and diagnostic tasks in both residential and commercial environments.

Advantages

The primary benefit of the UT256 is its specialized fork-style jaw, which simplifies the process of measuring current in crowded electrical panels or tight wiring configurations where traditional clamp meters might be too bulky. The integration of True-RMS technology provides reliable data accuracy, while the built-in non-contact voltage (NCV) detector enhances safety by allowing users to identify live wires without direct contact. Additionally, the device features a clear, backlit display and an intuitive interface, ensuring that technicians can work efficiently in various lighting conditions. The robust construction, combined with a 1-meter drop test rating and CAT III 600V safety certification, guarantees durability and peace of mind during daily professional use.

Suitable for

• Electrical troubleshooting and maintenance
• Measuring current in narrow cable conduits
• Identifying live voltage via NCV detection
• Automotive electrical diagnostics
• Residential and commercial wiring inspections

When it may not be suitable

This device is designed for currents up to 60A and is not suitable for high-current industrial applications exceeding this range. Furthermore, because it uses a fork-style sensor rather than a full-closing clamp, it is intended for specific cable-based measurements and may not be the optimal choice for applications requiring high-precision power quality analysis or measurements on very large busbars.

Key specifications

• Measurement range: Up to 60A AC/DC
• Technology: True-RMS
• Jaw opening: 10mm
• Safety rating: CAT III 600V
• Integrated NCV detector
• Display: Backlit LCD
• Power source: 2 x 1.5V AAA batteries
• Weight: 120g

How to use

To measure current, simply turn on the device and select the appropriate AC or DC mode. Place the conductor within the fork opening, ensuring the wire is positioned centrally for the most accurate reading. Use the Data Hold function to freeze the measurement on the screen if you are working in a position where the display is not easily visible. For NCV detection, move the tip of the fork near the suspected live wire; the meter will provide an audible and visual alarm if voltage is detected. Always ensure the device is switched off after use to preserve battery life, or rely on the automatic power-off feature.

What to consider before purchase

• Verify that your typical current measurements do not exceed the 60A limit.
• Ensure the 10mm jaw opening is sufficient for the diameter of the cables you intend to measure.
• Confirm that the CAT III 600V safety rating meets the requirements of your specific work environment.
• Consider the compact size if portability is a priority for your toolkit.

Usage recommendations: Always perform a self-test on a known live source before relying on the NCV function for safety. Keep the fork sensor clean and free of debris to maintain measurement accuracy. Replace batteries promptly when the low battery indicator appears to ensure consistent performance.
