ETCR3000B - Ground Resistance / Soil Resistivity Tester
I. Introduction
The ETCR3000B Ground Resistance / Soil Resistivity Tester is specially designed and manufactured for on-site measurement of ground resistance, soil resistivity, ground voltage, and AC voltage. It adopts the latest digital and microprocessor technology, with precision 4-wire, 3-wire, and simple 2-wire methods for measuring ground resistance. It incorporates FFT (Fast Fourier Transform) technology and AFC (Automatic Frequency Control) technology, providing unique anti-interference capability and environmental adaptability, with excellent repeatability, ensuring high accuracy, high stability, and high reliability for long-term measurements. It is widely used in electric power, telecommunications, meteorology, oil fields, construction, lightning protection, and industrial electrical equipment for measuring ground resistance, soil resistivity, ground voltage, and AC voltage.
The ETCR3000B Ground Resistance / Soil Resistivity Tester consists of the main unit, monitoring software, test leads, auxiliary ground rods, and communication cables. The main unit features a large LCD display with blue backlight and bar graph indication for easy reading. It can store up to 300 sets of data, and through the monitoring software, it enables historical query and real-time online monitoring, dynamic display, alarm indication, and functions such as historical data reading, viewing, saving, reporting, and printing.
