Clamp type digital grounding resistance testerProduct features:
1. Adopting advanced algorithms and digital integrated processing technology
2. Power on without self checking waiting, enter testing immediately
3. Breaking through the problem of bulky products, it is more in line with the characteristics of handheld instruments
4. Brand new exterior design, 6-key operation on the panel, direct performance
5. Added sound and light alarm function and interference signal recognition indication function
6. The measurement range has been increased to 0.01 Ω -1200 Ω, with 99 sets of stored data and lower power consumption. The large startup and operating current are less than 50mA
advantage:
1. Easy to operate and fast. When in use, there is no need to apply a grounding electrode or disconnect the grounding lead. Simply clamp the tested grounding wire with a caliper to read the grounding resistance value from the LCD screen.
2. The clamp type grounding resistance meter is a non-contact test, so it is very safe for both the user and the instrument.
3. The clamp type grounding resistance meter is an online test that measures the comprehensive value of the grounding body resistance and the line resistance, so it can test the contact condition between the grounding body and the grounding system. This cannot be measured using traditional methods.
4. High measurement accuracy. The clamp type grounding resistance meter does not require auxiliary electrodes and there is no electrode placement error.
5. Traditional methods require the insertion of two auxiliary electrodes with relative positioning requirements and the disconnection of the grounding body from the grounding system, which limits its use in many environments such as cement floors, mountainous rocks, high-rise buildings, and the inability to disconnect the grounding body from the grounding system. However, using a clamp type grounding resistance meter does not have these limitations.
brief introduction
Clamp on grounding resistance tester, also known as loop resistance tester, is used for testing grounding resistance. This instrument adopts a brand new black luxury screen design, displays resistance current on the same screen, and also has functions such as data storage, data retrieval, alarm, and automatic shutdown. The whole machine is beautiful and high-end, with a wide range, high resolution, convenient operation, easy portability, accuracy, reliability, stable performance, and strong anti-interference ability. Moreover, it has earthquake resistant, dust-proof, and moisture-proof structures, making it a commonly used and essential instrument for telecommunications, power, meteorology, computer rooms, oil fields, mechanical and electrical installation and maintenance, as well as industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring the grounding resistance of various telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding grids, lightning rods, etc.
Controlled by a microprocessor, it can accurately detect the grounding resistance. It uses fast filtering technology to minimize interference. Simultaneously providing functions such as data storage and data upload.
