Product description:
Intelligent loop resistance tester is ergonomically designed, in line with operating practices, use high-frequency switching power supplies and digital circuit technology for measuring the contact resistance of the circuit switch control device. Test current is DC 100A. In the case of DC 100A can be directly measured contact resistance test result with a large-screen LCD display, and with data storage, print, time settings and other functions, and another gear 50A for user selection; custom test time, maximum 599S, much larger than the standard requirements of 60S; resolution 0.01µO and very stable. Meet the power; the electricity sector on-site high voltage switch maintenance and high-voltage switch factory contact resistance testing requirements.
Technical index:
1. Measurement range: 0~2999.9µO
2. Resolution: 0~99.99, 0.01µO
100.0~2999.9, 0.1µO
3. Measured current: DC 50A, 100A, fixed output.
4. Accuracy : ±(0.5% rd+2d)
5. Continuous working time: 5s~599s
6. Display :LCD
7. Communication mode: USB
8. Power supply: AC220V±10% 50Hz
9. Power of the whole machine:600W
10. Maximum storage record: 200
11. Service conditions: temperature- 10?~40? humidity=80 %RH
12. Dimension: 360×300×250 mm3
13. Weight: 8kg (the accessories not included)
Feature:
1. High current, adopts new switching 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 result.
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 S-? AD to sample, digital signal processing technique, the maximum resolution up to 0.01µO.
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 result by temperature, meanwhile strengthen the resistance to shock by using the military connector.
6. Powerful: current could be 50A, 100A, measurement time 5s~599s, more powerful than other equipments.
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 result in time.
8. USB COMM.: The tester can communicate with computer through USB data line and upload the measured data to computer for further analysis and processing.
9. Easy to carry: small in volume, light in weight.
