UT261B User Manual (PDF)FAQs
Q1: What is the main difference between a standard indicator and the UT261B 3-phase sequence tester?
A: Unlike basic indicators, the UT261B 3-phase sequence tester is a multi-functional diagnostic tool. In addition to identifying phase rotation (Forward/Reverse) and missing phases, it is specifically optimized for motor rotation indication. It can determine the rotation direction of a motor even when it is not connected to a power source, making it an essential tool for pre-installation safety checks.
Q2: Why is the 45mm jaw opening important for industrial electricians?
A: The UT261B is equipped with a generous 45mm jaw opening. In industrial settings, power cables are often thick and bundled tightly. This wide jaw allows you to securely and easily clamp onto larger conductors and busbars without struggling for a connection, ensuring more stable and accurate 3-phase sequence measurements in distribution panels.
Q3: Can this 3-phase sequence tester survive a harsh construction or factory site?
A: Yes. The Xin Tester provided UNI-T UT261B is built for the field. It features a ruggedized, shock-resistant housing that has been tested to withstand 2-meter drops on hard surfaces. Its lightweight and compact design also make it highly portable, fitting easily into a tool bag or pocket for on-the-go maintenance tasks.
Q4: Is the UT261B safe for high-voltage industrial testing?
A: Safety is paramount. This 3-phase sequence tester meets strict international safety standards, including CAT II 1000V and CAT III 600V ratings. It is designed to safely handle voltage ranges from 90V to 600V AC, providing professional protection against electrical transients when working on fixed industrial installations.
Q5: How does the UT261B perform in dark or poorly lit working conditions?
A: The device is engineered for maximum visibility. It features a high-contrast LCD with an integrated backlight, allowing you to read sequence data clearly in any lighting. Furthermore, it includes a built-in flashlight at the top, which illuminates your workspace and connection points, eliminating the need to hold an external torch while testing.
