 Measures voltage between DC system and ground ranging from 0 to 300V.
 Measures grounding resistance up to 999KΩ for both busbars and each branch circuit
 It detects and measures AC voltage which interrupts in DC system. Detection range is from 0 to 288V.
 Fast signal positioning for the point of ground fault in branch circuit.
 It performs the function as accurate current meter with resolution up to 0.01mA.
 It could quickly pinpoint the ground fault without injecting signal to DC system.
 Arrow indication effectively helps users trace the signal and pinpoint the ground fault.
 Display of insulation index after signal detection on each tested branch circuit.
 Waveform display for tested circuit, indicating insulation status and current changes in tested circuit, it help users fast and effectively locate the point with grounding fault.
