Summary
HM6090-200A Contact Resistance Tester measures up to the latest power system standards--DL/T845.4-2004 designed for measuring loop resistance of Switching Control Equipment using High-frequency switching power supply technology and digital circuit technology. Test current of the Tester is DC 100A and 200A which is recommended in the national standards. The tester can measure the loop resistance at this value and display the result in digital and with function of storage, printing and time setting. Another 50A and 150A are optional. It is high precision and good stability and can meet most power systems' requirements in onsite high-voltage switches maintenance and high-voltage switches factory loop resistance measurement.
Advantage
1. High current, adopts new power techniques, can output current long time and continuously , overcome the malpractice of instantaneous current of the impulse type power, can effectively break through the oxide film of the switch contact, get accurate test results.
2. High stability, under strong interference, the last number displayed by the LCD within the range of ±1, with steady reading and good reproducibility.
3. 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 when testing, 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 components adopts imported components, uses temperature compensating circuit in perfect design which eliminates the effect to test results by temperature, meanwhile strengthen the resistance to shock by using the special connector.
6. Powerful: current could be 50A, 100A, 150A or 200A measurement time 5s~599s, more powerful than other equipment.
7. 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. USB dump: Store the data to U disk by USB interface, combining PC software for further analysis and processing of the measurement data.
9. Easy to use: small in volume, light in weight.
