TZY-JD2000 digital large-scale grounding resistance tester, also known as power frequency grounding resistance tester, grounding resistance meter, etc., is a commonly used instrument for checking and measuring grounding resistance. It adopts a new type of variable frequency AC power supply, dual frequency measurement technology, 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 characteristics of instrument testing are fast, simple, stable and reliable.

1. The output high open circuit voltage can reach 400V, and the larger voltage and current can reach 5A.

2. 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 100 sets of data, with a resistance measurement range of 0.000 Ω to 2000 Ω.

3. Measurement data can be printed out through a thermal printer, which has functions such as historical data reading, viewing, saving, and printing.
