This AN9612D Ground Resistance Analyzer is high performance instrument for grounding resistance test with excellent performance and rich features, LCD display, high-grade, beautiful, easy to learn. In addition to the high speed and high accuracy performance described in the specification table, the AN9612D analyzer also has rich auxiliary functions: 10 groups of memory, intelligent discrimination and sequence test.

1. Four-terminal test, accurate, reducing the error caused by the test line;
2. Judge whether the ground resistance exceeds the upper/lower limit;
3. Judge whether the output voltage exceeds the upper/lower limit;
4. Open circuit, over current, over voltage alarm;
5. Sound and display prompts for qualified test.
