The specially engineered slim meter body and thin fork design allow access to crowded electrical panels and tight wire bundles that would challenge traditional clamp meters. This space-optimized construction maintains measurement accuracy while providing the accessibility needed for today's increasingly compact electrical installations. For maintenance technicians working on modern equipment with densely packed wiring, the UT256's slim profile is an invaluable advantage.

Enhanced Safety Features

Safety is paramount in electrical work, and the UNI-T UT256 delivers with its CAT III 600V safety rating suitable for industrial environments. The integrated non-contact voltage (NCV) sensor provides an additional layer of protection by allowing you to detect the presence of voltage before making contact. Combined with audible and visual alarms, the UT256 keeps you informed and protected during operation, reducing workplace hazards.

User-Friendly Interface

The bright backlight display ensures visibility in poorly lit environments, while the intuitive button layout provides quick access to essential functions. Mode selection is straightforward, with dedicated functions for data hold, zero mode, and relative measurements. The auto power-off feature preserves battery life without interrupting your workflow, automatically shutting down after approximately 30 minutes of inactivity.

Durable Construction

Built to withstand the demands of professional use, the UNI-T UT256 has been tested to survive drops from heights up to 1 meter. This ruggedized construction ensures reliability in challenging work environments, from industrial facilities to construction sites. The easy-access battery door facilitates quick power source changes in the field, minimizing downtime.

Professional Applications

Electrical Contractors

For electrical contractors working in residential and commercial settings, the UNI-T UT256 provides the precision and accessibility needed for troubleshooting circuits, verifying loads, and performing quality inspections. The slim fork design is particularly valuable when working with modern electrical panels where space between conductors is limited.

HVAC Technicians

HVAC professionals rely on accurate current measurements to diagnose system issues and verify proper operation. The UNI-T UT256's ability to measure both AC and DC currents makes it ideal for checking compressor draw, fan motor performance, and control circuit operation. The thin profile allows measurements in tight equipment compartments without disconnecting wires.

Maintenance Engineers

Facility and maintenance engineers will appreciate the versatility of the UNI-T UT256 when performing routine equipment checks and troubleshooting. The non-contact voltage detection feature speeds up initial assessments, while the True RMS measurement ensures accurate readings regardless of the electrical noise common in industrial environments.

Frequently Asked Questions

What is the difference between a fork meter and a clamp meter?

A fork meter like the UNI-T UT256 features an open-ended fork design rather than the closed loop of a traditional clamp meter. This design allows for easier access to individual conductors in tight spaces without having to fully encircle the wire, making it ideal for crowded electrical panels and bundled wires.

Does the UNI-T UT256 measure AC and DC current simultaneously?

The UNI-T UT256 measures either AC or DC current based on the selected mode, not simultaneously. You can easily switch between AC and DC measurement modes using the function selector button.

Can the UNI-T UT256 measure voltage directly?

The UNI-T UT256 is specialized for current measurement and does not measure voltage directly. However, it does feature a non-contact voltage (NCV) detector that can identify the presence of AC voltage, which is useful for safety checks and preliminary troubleshooting.

How does True RMS measurement improve accuracy?

True RMS (Root Mean Square) technology provides accurate current readings regardless of waveform distortion. This is particularly important when measuring currents in systems with variable frequency drives, electronic lighting, or other non-linear loads that create non-sinusoidal waveforms.

What is the battery life of the UNI-T UT256?

With normal use, the two included 1.5V AAA batteries typically provide approximately 100 hours of operation. The auto power-off feature, which activates after approximately 30 minutes of inactivity, helps extend battery life significantly.

Is calibration required for the UNI-T UT256?

For most commercial and residential applications, the factory calibration is sufficient. However, for critical measurements or to maintain compliance with quality systems, annual calibration is recommended. UNI-T authorized service centers can provide traceable calibration services.
