Introduction
Warning
Read this Manual carefully before use the Instrument.
Generalization
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.
