VR-4106
Section One
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.

The Instrument conforms to the following Safety Requirements:
IEC61010-1（CAT Ⅲ 600V,POLUTION degreeⅡ）
IEC61557-1、 5 （Electronic safety requirements for low voltage distribution system below AC 1000v and DC 1500v ）

Basic Measurement Function
2/3/4- pole earth resistance measurement
Earth resistivity （ρ）calculation

Earth Resistance Measurement employs AC simulation test, 4-kind of testing frequencies （ 94Hz、 105Hz、 111Hz、
128Hz）,which are selectable by hand to reduce impacts from low interference sources.

Auxiliary Earth Resistance Measurement Function
Testing and displaying auxiliary earth resistance.

Warning Display Function for auxiliary earth resistance upper-limits
Displaying warnings for inaccurate measurements due to high auxiliary earth resistances

Auto-range Function in Resistance Measurement and OL displays for over range.

Indication Functions for high interference voltage.

Measurement Function for series interference voltage.
