NDWZD-III Portable DC Ground Finder
basic information
Detailed parameters
Reference standard: DL/T856-2004.
Features:
● The instrument consists of three parts: signal generator, fault detector and signal collector （plier）.
● The instrument adopts high-resolution （0.1mA） signal sampling DC clamp meter, which can realize the positioning of multi-point grounding and high-resistance grounding point;
● The instrument has a grounding point direction display function, including: LCD display, indicator indication, and voice prompt display in three directions, which can efficiently and quickly handle the positioning of complex branches or ground points in the loop.
Main parameters: Finder.
