SXHL-100A Loop Resistance Tester

Product Introduction

SXHL-100A 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 national standard recommended DC 100A. The circuit resistance can be directly measured at 100A and displayed digitally. This 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 in the 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.SXHL-100A Loop Resistance TesterConvenient to carry: small size and light weight.
