This is a great phase rotation meter. **Q: Does it work on 480-V delta and wye systems?** A: Yes. It has worked perfectly on all systems and all voltages up to and including 480 for us. Excellent tool and much safer. **Q: Will this work on the output of a VFD?** A: It should as long as the VFD is running (being commanded to go a direction at 50-60 HZ) **Q: Can this be used on single phase 240 volt service?** A: Hi, phase sequence is only used to determine the correct phasing of the 3 phase supply. You need not use this device for single phase at all. You only need a volt meter to ensure that the supply is in order in terms of L N E. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by J***F on January 3, 2026* Great product.
