UNI-T UT261A 3-Phase Rotation Meter | AC Phase Sequence Indicator 40V-690V

Overview

The UNI-T UT261A is a compact, rugged tester designed for quick verification of three‑phase systems. It helps you confirm phase rotation and spot a missing phase while offering essential electrical measurements. Its lightweight build makes it a practical companion on job sites, in panel rooms, or at service calls where speed and clarity matter.

Key Benefits

• High‑accuracy rotation measurement with a wide 45 mm jaw opening for easy clamping on conductors.
• Broad measurement capabilities: 1000 A AC current, up to 1000 V AC/DC voltage, and 600 A inrush current measurement.
• Rugged yet portable: compact form factor, low weight, and straightforward operation for field use.
• Useful features: auto range, backlight, low battery indicator, data hold, relative mode, diode check, duty cycle, and flashlight for dim environments.
• Safety and compatibility: CAT II 1000 V and CAT III 600 V ratings, suitable for a range of electrical tasks.

Practical Use Scenarios

In real-world environments, technicians can rely on UT261A to quickly assess motor wiring at control panels, verify correct three‑phase connections before commissioning, and perform basic checks on circuit integrity. The device supports on-site decisions without lengthy setup, helping teams move from testing to troubleshooting with confidence.

• Verify phase sequence and identify missing phases before starting a motor or mixer.
• Confirm phase order during panel commissioning or rewiring projects.
• Conduct basic measurements (resistance, capacitance, and frequency) to aid diagnosis.
• Assess high‑current and high‑voltage conditions safely with clearly displayed readings.
