VS-3001 Digital Earth Resistance Tester

VS-3001 Grounding Resistance and Soil Resistivity Tester is specially designed and manufactured for on-site measurement of grounding resistance, soil resistivity, grounding voltage and AC voltage in combination with the new lightning protection grounding resistance testing standard. The test current is up to 20mA. Digital and micro-processing technology, precision 4-wire method, 3-wire method and simple 2-wire method to measure grounding resistance, import FFT (Fast Fourier Transform) technology, AFC (Automatic Frequency Control) technology, automatically identify interference and select measurement frequency, make interference Minimize the impact and provide a more accurate ground resistance value. It has unique anti-interference ability and environmental adaptability, and has good consistency of repeated tests, ensuring high precision, high stability and high reliability of long-term measurement. It is widely used in the measurement of grounding resistance, soil resistivity, grounding voltage and AC voltage of electric power, telecommunications, meteorology, oil field, construction, lightning protection and industrial electrical equipment.

VS-3001 grounding resistance and soil resistivity tester, also known as precision grounding resistance tester, four-wire grounding resistance tester, two-three-four-wire grounding resistance tester, soil resistivity tester , consists of host, data software, test line, Auxiliary ground rods, communication lines, etc. The special tool box type design for the host, using polypropylene plastic as raw material, adding new composite fillers for one-time injection molding , low density, strength, stiffness, hardness, wear resistance, heat resistance, insulation performance is more superior, its box body It can withstand a pressure of about 200kg, ensuring high precision, high stability and high reliability in various environmental tests. The large LCD display of the host, with backlight and bar graph indication, is clear at a glance. At the same time, it can store 300 sets of data, and the functions of historical data reading, viewing, saving, reporting, and printing can be realized through data software.

Technical Specifications

Key Features

High Accuracy & Anti-interference‌: Automatic frequency selection (412Hz/825Hz/1280Hz) helps minimize interference. Accuracy in ground resistance measurement can reach ±2%rdg±5dgt for the range 0.000Ω–10.00kΩ.

Robust & Portable Design‌: Comes in an industrial-grade base station toolbox rated to withstand 200 kg of pressure. It is lightweight (base station 2.7 kg) and suitable for field use.

Wide Measurement Range‌: Ground resistance: 0.000Ω–200 kΩ; Soil resistivity: 0.00 Ω·m–9999 kΩ·m; Grounding/AC Voltage: 0.001–600.0 V.

User-Friendly Operation‌: Large LCD with backlight, test progress bar, countdown indicator, and intuitive function dial/buttons. It can automatically detect interference (NOISE warning >5V) and overload conditions (OL display).

Data Management‌: Stores up to 300 sets of data. Data can be held, reviewed, deleted on the device, and transferred via ‌RS232/USB to a PC‌ using provided software for reporting and printing.

Safety Compliance‌: Meets IEC61010-1 (CAT III 300V, CAT IV 150V), with overload protection and clear safety warnings regarding isolation, voltage limits (do not exceed 600V), and proper operation.
