Product Description
20mA Strong Anti-Interference Ability Digital Grounding Resistance Tester
Product introduction
The ZXET3005 Digital Grounding Resistance Tester is designed and manufactured according to the new lightning protection grounding resistance detection standard. The short-circuit test current reaches 20mA. The precision 3-wire method or simple 2-wire method measures the grounding resistance. The FFT (fast Fourier transform) technology is introduced, AFC (Automatic Frequency Control) technology has unique anti-interference ability and environmental adaptability, and the consistency of repeated testing is strong. It is widely used in the measurement of grounding resistance and grounding voltage in electric power, telecommunications, meteorology, oil fields, construction, lightning protection, and industrial electrical equipment.
Features
1. Two and three-wire method for testing grounding resistance, loop resistance, and on-resistance;
2. Equipotential connection resistance, ground voltage, AC voltage test;
3. Designed according to the new standard of meteorological lightning protection grounding resistance test;
4. The grounding resistance test current reaches 20mA;
5. Toolbox design, pressure resistance 200kg;
6. FFT, AFC technology, strong anti-interference ability;
7. Range: 0.000Ω～3000Ω;
8. Resolution: 0.001Ω.
