Audited Supplier 200A Contact resistance tester/Digital switching circuit resistance detector/Microhmmeter/megger
Product characteristics
1.320 ×240 LCD display, high speed thermal printer.
2. Measurement function: fast measurement, 10S measurement, 60S measurement.
3. The instrument has the characteristics of small volume, light weight, strong anti-interference ability, high precision, easy operation, perfect protection function and so on.
4. Using new power supply technology, it can output large current continuously for a long time and output at multiple current gears.
5. Using the precision instrument operational amplifier and high precision quadruple integration A/D converter, combined with high performance 16 bit single chip microcomputer, the system automatically switches the magnification according to the signal size, which ensures the test accuracy of the product.
6. The test current comes from the high-precision 100A switching constant current power supply, and the test is fast and accurate without manual adjustment.
7. The four-terminal connection method is adopted to effectively eliminate the influence of the test wire resistance on the test result.
8. This product also has a real-time calendar clock designed to provide time basis for printing and saving data.
9. Data storage and historical data browsing function, can store 1000 groups of data, and has power failure protection function.
10. The test current is large and meets the requirements of the national standard for testing contact resistance.
11. Long working time, with overheat protection circuit, the instrument is reliable and stable.
12. Man-machine dialogue keyboard operation mode, intelligent working process.
13. Extensible RS232 interface for communication with the PC.
