1. For latest power supply technology, the tester can continuously output high current2. High stability. under strong interference, the last number displayed by the LCD is within the range of ±1d, with steady reading and good reproducibility3. High precision: adopts double channels high-speed 16bits Σ-Δ AD to sample, digital signal processing technique, the maximum resolution up to 0.01μΩ.4. Intelligent: use high performance CPU, system can switch the measurement range according the size of the signal during testing to ensure the accuracy. The over-temperature protection circuit can auto stop output the current when the device exceeds the rated temperature to ensure the safety.5. High quality: key parts are imported components, with temperature compensating circuit in perfect design which eliminates the effect of ambient temperature6. Powerful: several modes of currents for option7. Friendly man-machine interface: enter the data by rotating mouse, easy and convenient, can set the data, time by yourself, save and print the test results in time.8. Several communication modes: can connect and upload the data to the PC by RS232 or USB, for testing personal further analysis and processing.9. Easy to use: small in volume, light in weight.Measuring range: 0~2999.9μResolution: 0~99.99: 0.01μΩ, 100.0~2999.9: 0.1μΩMeasuring current: DC50A,100A,150A,200A fixed outputAccuracy: ±(0.5% rd+2d)Continuous working time: 5s~599sDisplay: Large LCDCommunication interface: USB or RS232 serial portWorking power supply: AC220V±10% 50HzTotal power: 1200WMaximum storage: 200 recordsWorking environment: Temperature -10ºC~40ºChumidity≤80 %RHDimension: 380x300x260 mm3Weight: 8 KG (accessories excluded)
