ES3002 LCD Digital Double-clamp Earth Resistance Tester Ground Resistance Voltage Meter Avoid Thunder Rod Measuring instrument Tools

Description
ES3002 double clamp multifunctional ground resistance tester is also called double clamp ground resistance tester. It is an advanced ground resistance tester that integrates multiple measurement methods. In addition to the traditional function of auxiliary grounding resistance measurement, this meter also has the unique function of unassisted grounding measurement. It adopts super large LCD gray-white screen backlight display and microprocessor technology, through microprocessor control precision 4-wire method, 3-wire method and simple 2-wire method, selection method, double clamp method to measure the ground resistance test. It adopts the design of large-caliber current clamp and double-jaw measurement technology. There is no need to hit auxiliary ground poles and isolate the grounding body from the equipment, realizing online measurement. It is widely used in telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, avoid thunder rods, etc. The instrument has the characteristics of accurate, fast, simple, stable and reliable testing.
The ES3002 double-clamp multifunctional ground resistance tester is controlled by a microprocessor and can accurately detect ground resistance, soil resistivity, ground voltage, DC resistance and AC current. It uses fast filtering technology to minimize interference. The resistance value of the auxiliary electrode is displayed on the same screen, which is convenient for judging the measurement error caused by environmental factors, and is convenient for measuring the true resistance value of the ground more accurately. At the same time, 500 sets of data can be stored, and the data can be monitored online through the monitoring software. The USB data is uploaded to the PC and has unique functions such as value retention and intelligent alarm prompts.
The ES3002 double clamp multifunctional ground resistance tester is composed of a host, monitoring software, test wire, USB cable, and grounding pin. It has the functions of reading, reviewing, saving, reporting, and printing historical data.
