VICTOR 4110D Three Channel DC Resistance Test

VICTOR 4110D three channel DC resistance tester, also known as power frequency grounding resistance tester, grounding resistance meter, etc., is a commonly used instrument for testing and measuring grounding resistance. It adopts a new type of variable frequency AC power supply, dual frequency measurement technology, ultra large touchable color screen, and microprocessor technology to meet the impedance requirements of two-wire, three wire, and four wire tests. At the same time, it can measure parameters such as soil resistivity, step voltage, distributed potential, contact voltage, and current phase angle. Suitable for telecommunications, power, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc., in compliance with the standards for testing instruments for power substations and lightning protection devices. The instrument testing is characterized by precision, speed, simplicity, stability, and reliability.
The VICTOR 4110D three channel DC resistance tester outputs an open circuit rated voltage of 27V and a short-circuit current of up to 20A. The microprocessor control and automatic dual frequency technology can accurately measure and calculate the grounding impedance value at 50Hz power frequency under strong interference conditions, and the large screen display is clear at a glance. Simultaneously store 500 sets of data, with a resistance measurement range of 0.1u Ω to 5000 Ω. Measurement data can be printed using a thermal printer, exported from a USB flash drive and computer software.
