1、 Product Introduction:
The operation panel of this instrument adopts ergonomic design that conforms to operating habits. It uses high-frequency switching power supply and digital circuit technology, which is suitable for measuring the circuit resistance of switch control equipment. The test current adopts the recommended DC 100A by the national standard. The circuit resistance test results can be directly measured at 100A DC and displayed on a large LCD screen with functions such as data storage, output printing, and time setting. There is also a 50A gear for users to choose from; The maximum set time for custom testing is 599 seconds, far exceeding the standard requirement of 60 seconds; It is the only contact resistance tester in China that can achieve a resolution of 0.01 μ Ω and is very stable. Its performance exceeds that of imported high current micro ohmmeters. Meets the requirements of on-site high-voltage switch maintenance and high-voltage switch factory circuit resistance testing by the power and supply departments.
Product nickname:Contact resistance tester, intelligent circuit resistance tester, switch circuit resistance tester, contact circuit resistance tester, fully automatic circuit resistance tester, digital micro ohmmeter, micro ohmmeter
2、 Product features:
1. High precision: Adopting the latest digital signal processing technology of dual channel high-speed 16 bit ∑ - Δ AD sampling, the highest resolution reaches 0.01 μ Ω, which is currently the only contact resistance tester in China that can achieve 0.01 μ Ω resolution and is very stable. Its performance exceeds that of imported high current micro ohmmeters.
2. Intelligence: When measuring imported high-performance CPUs, the system automatically switches the range according to the signal size to ensure testing accuracy. The over temperature protection circuit can automatically stop outputting current when the instrument exceeds the set temperature to ensure safe use of the instrument.
3. Human computer interface friendly: Rotating the mouse to input data is convenient, fast, and allows for automatic setting of instrument date and time. Real time saving of measurement data and instant printing of measurement results are also available.
4. High quality: All key components are imported, and the cleverly designed temperature compensation circuit effectively eliminates the influence of environmental temperature on measurement results. The use of military connectors enhances the anti vibration performance.
5. Powerful function: The current can be freely selected between 50A and 100A, and the testing time can be set freely within 5s~599s, overcoming the shortcomings of other similar instruments that cannot set measurement time or have too short continuous working time, far exceeding the performance of other similar instruments.
6. High current: By adopting the latest switching 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.
7. High stability: Under severe interference conditions, the last digit of the LCD screen can remain stable within a range of ± 1 word, with stable readings and good repeatability.
8. USB Transfer: Transfer measurement data to a USB flash drive through a USB interface, and further analyze and process the measurement data using upper computer software.
9. Easy to use: small size, light weight, and easy to carry.
