1.5 LED Indicators for Clear Visual Feedback This phase rotation meter features five LED indicators, ensuring users can easily and clearly observe the phase sequence results. The multiple LEDs provide clear feedback, making it simple to identify the correct phase rotation in various electrical systems. 2. Battery Design for Continuous Operation Unlike other testers that require batteries, this phase rotation meter operates without a power source. This design ensures the tester is always ready for use, eliminating inconveniences caused by dead batteries or the need to carry additional components. 3. Insulated Test Leads for Safety Equipped with doubleinsulated test leads, this rotation tester meets safety standards. The 700 mm (27.56inch) long cables offer sufficient length for different testing scenarios while ensuring user safety—a critical feature for electrical work. 4. Wide Voltage Range for Versatile Use This phase rotation meter operates within a voltage range of 60V to 600V AC, making it suitable for diverse applications. Whether testing phase sequence at home, in a factory, or during equipment maintenance, this tester accommodates a wide range of electrical systems.
