Nickname: Circuit Resistance Tester；Circuit Breaker Tester
Feature:
1.large current: the circuit resistance automatic tester adopts new power technology, can output large current continuously for a long time, overcome the drawbacks of impulse power instantaneous current, can effectively breakdown the oxide film of the switch contact, get good test results.
2.high stability: in serious interference conditions, the LCD screen last data can be stable within the range of ±1word, stable reading, good repeatability.
3.High precision: The use of dual-channel high-speed 16-bit Σ-ΔAD sampling, new digital signal processing technology, the highest resolution of 0.01μΩ, is currently able to reach the resolution of 0.01μΩ and very stable contact resistance tester, the performance exceeds the imported large current micrometer.
4.Intelligent: The use of imported high performance CPU, measuring system according to the size of the signal automatically switch range, to ensure the testing accuracy of the product. Overtemperature 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: the key components are all imported components, through the clever design of the temperature compensation circuit effectively eliminate the impact of environmental temperature on the measurement results, the use of military connectors to enhance the vibration resistance.
6.Powerful: current 50A, 100A, 150A, 200A free choice, test time in fast, 10 seconds, 30 seconds, 60 seconds, arbitrary choice, far beyond the performance of other similar instruments.
7.Friendly man-machine interface: touch screen control, convenient and quick, independent setting instrument date and time, real-time saving measurement data, real-time printing measurement results.
8.USB transfer: transfer the measurement data to the USB disk through the USB interface, and further analyze and process the measurement data combined with the upper computer software.
9.Easy to use: small size, light weight, easy to carry.
