Product Introduction

Didital ground resistance tester rejects the traditional manual manual power generation method, adopts advanced medium and large scale integrated circuit, and applies DC/AC conversion technology to combine the three-end button and four-end button measurement mode into a new type of Ground Resistance meter..

The working principle is that the DC/AC converter in the machine changes DC into low-frequency constant current of AC, and the circuit is formed by auxiliary ground electrode C and measured object E, which generates AC voltage drop on the measured object, and is fed into AC amplifier for amplification through auxiliary ground electrode P, and then sent to the meter head for display through detection. With the aid of multiplying power switch, three different quantity limit can be obtained: 0 ~ 2 Ω, 0 ~ 20 Ω, 0 ~ 200 Ω.

Didital ground resistance tester is suitable for measuring Ground Resistance of various devices and conductor Resistance of low Resistance in electric power, post and telecommunications, railway, communication, mining and other sectors; Didital ground resistance tester also measures soil resistivity and Ground voltage.
