| Function | Frequency measurement, phase measurement, phase sequence display, *voltage measurement, voltage verification | 
		
			| Nuclear phase mode | Contact nuclear phase: bare wire below 35kV or wire with insulating sheath below 220kV can contact the non-contact nuclear phase of the wire core. When the bare line voltage exceeds 35kV, non-contact testing must be used, and the probe is gradually approaching the core phase of the conductor.
