An overview,

The reliable and effective connection between grounding downlink and ground network is the fundamental guarantee of equipment operation. Therefore, in "Twenty-five Key Requirements for Preventing major Accidents in electric power production", the conduction detection of grounding device lead down line is clearly proposed. The company developed and produced a series of grounding lead down the conduction tester using 32-bit ARM kernel as the processing core, the whole machine control, automatic self-calibration, steady flow judgment, data processing, resistance display and other functions, the instrument can directly use the internal battery work, greatly facilitate the use of field staff.
