## Summary description

Unit UT261B is a portable phase sequence meter for checking phase rotation in three‑phase electrical systems. Designed for quick diagnostics, it detects phase order and presence to verify correct motor and equipment connections. Compact and handheld, it is suitable for electricians and maintenance technicians for on-site troubleshooting and commissioning of industrial and commercial power installations.

## Long description

Unit UT261B is a compact, handheld phase sequence meter designed to check phase rotation in three-phase electrical systems. The device senses the order of phases and verifies the presence of all three phases to help confirm correct motor and equipment connections. Its portable form factor makes it suitable for quick diagnostics and on-site verification in industrial, commercial and light‑industrial installations.
Advantages
The Unit UT261B provides straightforward detection of phase order and presence without complex setup. Its compact construction and intuitive operation enable rapid testing during commissioning, maintenance and troubleshooting. The instrument reduces the need for more invasive checks by identifying incorrect phase rotation that can cause motor reversal or equipment malfunction.
Suitable for
 Verification of phase rotation when installing or replacing three-phase motors
 Routine maintenance checks on distribution panels and motor control centers
 Troubleshooting phase loss, incorrect wiring or unexpected equipment behavior
 Commissioning of industrial machinery, HVAC systems and large electrical loads
Key specifications
 Function: phase sequence detection and presence indication for three-phase systems
 Form factor: handheld, portable meter for field use
 Input: designed for standard three-phase voltage ranges used in industrial and commercial installations
 Display/indication: clear visual indicators for rotation direction and phase presence
 Durability: built for on-site use with a compact enclosure suitable for electrical environments
How to use
Before testing, isolate equipment according to local safety rules and ensure personal protective equipment is worn. Connect the meter's probes or clamps to the three phase conductors as instructed in the user manual, ensuring secure contact. Power to the tested circuit should be present for the meter to detect phase order; observe the device's visual indicators to determine correct rotation (clockwise or counterclockwise) and confirm presence of all phases. Remove connections once the measurement is complete and restore any safety barriers.
Usage recommendations
Use the UT261B only on live three-phase circuits when required and follow applicable electrical safety procedures. Combine phase sequence checks with insulation and continuity tests during commissioning to ensure reliable motor installation and prevent damage from incorrect rotation. Store the meter in a dry, protected place and inspect probes and contacts regularly for wear.
