The instrument is a multifunctional earth resistance/earth resistivity tester equipped with a microcomputer.
The instrument employs digital signal settlement technology, which can draw earth measurement signals, possess features of high frequency, high accuracy and high resistance, and measure earth resistance/ earth resistivity accurately. The instrument can execute standard 3POLE and 4POLE earth resistance measurements and has 2POLE earth resistance measurement and earth resistivity calculation functions as well.
