This Class 0.5 certified live-line tester adopts isolated dual signal acquisition architecture to deliver stable phase readings while circuits stay energized without power shutdown. Its optimized anti-disturbance circuit suppresses electromagnetic interference generated by relays and inverters in dense control cabinets, securing accurate phase offset data for CT vector verification and wiring troubleshooting. The ergonomic handheld body paired with matched insulated clamps enables rapid on-site testing for grid acceptance and routine maintenance, with recorded test data retained permanently inside built-in memory for audit archives.
