Advantages
1. High current: Using the latest switching power supply technology, it can continuously output high current for a long time, overcoming the drawback of pulse type power supply instantaneous current, which can effectively break through the switch contact oxide film and get good test results.
2. High stability: Under severe interference conditions, the last data of the LCD screen can be stable within ±1 word, with stable readings and good repeatability.
3. High precision: Adopt double-way high-speed 16-bit Σ-Δ AD sampling, the latest digital signal processing technology, the highest resolution of 0.01μΩ, is the only domestic contact resistance tester can reach 0.01μΩ resolution and very stable, the performance exceeds the imported high-current micro-ohmmeter.
4. Intelligent: imported high-performance CPU, the system automatically switches the range according to the signal size when measuring to ensure the accuracy of the test. Over-temperature protection circuit can automatically stop the output current when the instrument exceeds the set temperature to ensure the safe use of the instrument.
5.High quality: All key components are imported, and the temperature compensation circuit is cleverly designed to effectively eliminate the influence of ambient temperature on the measurement results, and the use of military connectors enhances the vibration resistance.
6. Powerful: free choice in current 50A, 100A,150A，200A test time in fast, 10 seconds, 30 seconds, 60 seconds, any choice, far more than the performance of other similar instruments.
7. Friendly human-machine interface: touch screen control, convenient and fast, independent setting of the instrument date and time, real-time saving of measurement data, instant printing of measurement results.
8. USB transfer: transfer measurement data to U disk through USB interface, combined with the upper computer software for further analysis and processing of measurement data.
9. Easy to use: small size, light weight, easy to carry.
