HZJD-3002E Double Clamp Earth Resistance Meter

I. Introduction

This advanced grounding resistance tester integrates a variety of measurement methods. In addition to the traditional function of measuring grounding resistance with auxiliary electrodes, it also offers the unique capability of measuring without auxiliary grounding. It features a large LCD gray-screen backlit display and utilizes microprocessor technology.

Measure Your Way:
Choose from 4-wire, 3-wire, 2-wire, selective, or double-clamp methods. Need on-line testing without disconnecting? The large-diameter dual-jaw clamp lets you measure without auxiliary electrodes-no isolation required.

Built for the Field:
Telecom, power, meteorology, oil fields, distribution lines, towers, gas stations, factories, lightning protection-wherever you work, this tester delivers fast, stable, and reliable results.

II. Range and Accuracy

Remark：

1. Reference conditions: accuracy with Rh Rs < 100Ω.

Working conditions:Rh max＝3kΩ+100R＜50kΩ;Rs max＝3kΩ+100R＜50kΩ

2.Depends on the measurement accuracy of R,π=3.14, a:1 m～100m;

Notes

1,Calibration

The calibration cycle varies depending on the customer's usage conditions or environment. It is recommended to determine the calibration cycle according to the customer's usage condition or environment, and entrust the company to carry out calibration on a regular basis.

2,Cleaning

To remove dirt from the instrument, gently wipe it with a soft cloth moistened with a small amount of water or neutral detergent. Gently wipe the display area with a dry, soft cloth.
