1. Widely applied in electric power, telecommunications, meteorology, oil field, architecture and industrial electrical equipment, etc.
2. When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, safer and faster.
3. Large capacity , can store 99 units data, lower power consumption, maximum operating current less than 50mA, continuously working for 30 hours.
4. New design, panel with 6 buttons, better performance. Increase sound and light alarm function, and the interference recognition indicator function.
5. With battery voltage low indication function, storage data full indication, over range indication, automatic shutdown function.
