Overview
The SXHL-300A circuit resistance tester uses the recommended national standard for DC 100A, 200A, and 300A to test the current. It can directly measure the circuit resistance at 100A, or at 200A and 300A
Product Details
Product Introduction
SXHL-300A Loop Resistance TesterIt is designed based on the power implementation standard DL/T845.4-2004 of the People's Republic of China, using a combination of high-frequency switching power supply technology and digital circuit technology. It is suitable for measuring the circuit resistance of switch control equipment. The test current adopts the recommended national standards of 100A, 200A, and 300A DC. The circuit resistance can be directly measured at 100A current, or at 200A and 300A current, and the test results are displayed in numbers. The instrument measures accurately and has stable performance, meeting the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing for power and supply departments.
performance characteristics
1. High current: By adopting new power supply technology, it can continuously output high current for a long time, overcoming the drawbacks of instantaneous current in pulse power supplies. It can effectively penetrate the oxide film of switch contacts and obtain good test results.
2. Strong anti-interference ability: Under severe interference conditions, the last digit data of the LCD screen can be stable within ± 1 word range, with stable readings and good repeatability.
3. Long service life: All use high-precision resistors, effectively eliminating the influence of environmental temperature on measurement results, and the use of connectors enhances anti vibration performance.
4. Convenient to carry:SXHL-300A Loop Resistance TesterSmall size and light weight.
