5. Technical features and advantages:
1. Simplified Chinese WINDOWS software interface, easy to operate.
2. Quickly connect and replace the cable to be tested through the transfer cable or transfer box, which is suitable for multi-variety and large-volume cable testing.
3. With the self-learning function, it can quickly learn the unknown sample line connection relationship and the actual impedance value and capacitance value, which is convenient for editing and saves the trouble of manually inputting the connection relationship.
4. With auxiliary assembly function, through fast on-off scanning, the test point contacted by the probe can be quickly found, and the assembly position of the core wire can be displayed. Greatly improve the assembly speed and reduce the core wire identification process.
5. It has the function of system verification: verify and correct the signal source, detect the capacitance and resistance of the system, and eliminate the influence of distributed parameters.
6. With system self-checking function: automatically check the internal signal source, A/D, D/A and channel board of the system to ensure reliable operation of the machine and correct test results.
7. 500 points/second fast on-off test, can quickly display the test connection status, automatically find and display the error point.
8. Automatic grouping and combination short-circuit test to detect all possible short-circuit errors (ie wrong connection, multi-connection).
9. The program controls the automatic testing process, which can test the product cable many times at any time, which is convenient for quality management and greatly improves the work efficiency.
10. Precise resistance measurement by four-wire test method detects small changes in contact resistance, and finds quality hidden dangers such as poor contact, broken strands of conductor cores, and missing parallel wires.
11. Adjust the test parameters of high voltage (insulation / withstand voltage) at will to meet the test requirements of different cables and core wires, improve the test efficiency and ensure the test accuracy.
12. Quickly test the insulation/voltage resistance between any two core wires, and find out all possible defects such as poor insulation, voltage resistance and overcurrent.
13. Boost delay: the voltage rises evenly from 0v to the delay time of the set output, eliminates the influence of distribution parameters, and meets the requirements of cables with large distribution parameters (shielded wire, extra-long cable, twisted pair, etc.).
14. Pressurization delay: ensure that the high voltage is loaded on the cable to be tested and maintain the high voltage, continuously monitor the leakage current, and record the maximum value.
15. Step-down delay: the delay time for the voltage to drop from the set output to 0v, eliminate the distribution parameters, ensure safe operation, and realize high-current testing.
16. The test results can be counted and stored or printed.
17. Password protection provides multi-level access rights for operators/engineers, which is convenient for operation management, quality management and safety management.
