Portable Design Earth Insulation Tester , Digital Ground Resistance Tester

Introduction

The instrument is a newly developed earth resistance tester, which abandons the traditional way of generating electricity by hand operation, advanced middle-large scale integrated circuits and applies DC/AC transformation technology to combine three-terminal measurement method and four-terminal measurement method into one model.

Features

1.High-strength aluminum alloy shell body, the circuit equips with phase locked loop and switched capacitor filter, based on which the instrument play an effective role in shielding power frequency and radio frequency interference.

2.DC/AC converter can transform DC current into AC low-frequency constant current for the measurement.

3.Auxiliary grounding resistance are allowed to change in the range of 0 ~ 2KΩ (R_C), 0 ~ 40KΩ (R_P), that will not affect measurement results.

4.No need manual adjustment to zero, with three and a half bits LCD display, the instrument can be used for measuring the grounding resistance, low conductor resistance, soil resistivity and AC voltage to ground.

If tested loop encounter failure, the screen displays "1" indicating overflow, which consistent with conventional measurement practices.
