What is 4-Wire Earth Resistance Tester Specs about?

This document describes an instrument that measures 4-wire earth resistance and resistivity. It has features such as optical data transmission, data storage, auto-ranging microprocessor control, and testing of earth resistance at multiple ranges from 20Ω to 2000Ω. It also measures earth voltage from 0-300V AC and performs 2-wire, 3-wire, and 4-wire tests using a constant current method at 820Hz. Test results and measurements can be transferred to a PC.
