Description
Overview
GAOTek product is mainly used for underground power cable (especially the single core high voltage cable) metal sheath grounding fault accurately pinpointing, also can be used in the auxiliary pinpointing of core grounding fault (in the case of sheath have been destroyed).
Features
- High sensitivity and wide response range
- Digital signal processing technology, direct display signal waveform, strong anti-interface ability
- Automatic zero adjustment, counteract the effect of ground potential change
- Built in large capacity lithium-ion battery pack
- Solid case, light weight and portable
