Easy phase sequence detection: Quickly determine forward (clockwise) or reverse (counterclockwise) phase sequence by connecting test leads to L1, L2, and L3 inputs. Enables safe and efficient electrical work and prevents incorrect motor rotation. Clear visual indicators: A green power indicator shows the tester is ready, while illuminated R and L indicators provide a straightforward readout of the phase sequence for reliable wiring checks. Comprehensive testing capabilities: Supports wired phase checks using crocodile clips and magnetic field detection, delivering versatile functionality that is essential for technicians and engineers. Practical applications: Verify correct phase sequence before starting threephase motors in installations or after relocation. Troubleshoot and confirm phase in switchgear, transformers, or distribution panels during maintenance. Confirm phase when replacing drives or upgrading equipment to ensure proper motor rotation and safe operation.
