Product Introduction

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.

Product Characteristics

1、The Didital Ground Resistance Tester adopts high-strength aluminum alloy as the housing. In order to prevent power frequency and rf interference the phase-locked loop synchronous tracking and detection mode is adopted on the circuit and the switch capacitor filter is equipped to make the meter have better anti-interference ability
2、DC/AC conversion technology is adopted to convert DC into AC low-frequency constant current for easy measurement.
3、Allow auxiliary grounding resistance of 0 ~ 1.8kω (RC) 0 ~ 40KΩ (RP) shall not affect the result of measurement.
4、Didital Ground Resistance Tester does not require manual adjustment of balance. 3(1/2) position LCD shows that in addition to measuring Ground Resistance low Resistance conductor Resistance soil resistivity and ac Ground voltage can also be measured. If the test circuit does not display &ldquo on the header; 1 & throughout; Stands for overflow in line with conventional measurement habits.
