1. Test object
Cables, harnesses, backplanes and related components such as resistors, capacitors, diodes, etc.
2. Test items
On-off, impedance, capacitance, PN junction and other tests
3. Product Features
●Simplified Chinese WINDOWS software interface, easy to operate
●Quickly connect and replace the cable to be tested through the transfer cable or transfer box, suitable for multi-variety and large-scale cable testing
●With self-learning function, it can quickly learn the unknown sample wiring by itself relationship, easy to edit, save the trouble of manually inputting the wiring relationship
●Auxiliary assembly function, through fast on-off scanning, can quickly find out the test point contacted by the probe, and display the assembly position of the core wire. Greatly improve the assembly speed and reduce the core wire identification process ●Have system
verification function: check and correct the signal source, detect system capacitance, eliminate the influence of distributed parameters D/A , channel board to ensure reliable operation of the machine and correct test results

points / second fast on-off test, which can quickly display the test connection status, automatically find and display error points
Automatic grouping and combination short circuit test, detection All possible short-circuit errors (ie misconnection, multi-connection)
Program control automatic test process, which can test product cables multiple times at any time, which is convenient for quality management and greatly improves work efficiency
Four-wire test method for precise resistance measurement and detection Small changes in contact resistance can detect quality hidden dangers such as poor contact, broken strands of wire cores, and leakage of parallel wires.
Quickly combine the detection of insulation / voltage resistance between any two core wires, and find out all possible poor insulation and resistance. Defects such as pressure overcurrent
●Boost delay: The voltage rises evenly from 0V to the set output, eliminating the influence of distribution parameters, and meeting the test of cables with large distribution parameters (shielded cable, extra-long cable, twisted pair, etc.)
●The test results can be counted, And for storage or printing
Password protection Set operator / engineer multi-level access rights, convenient for operation management, quality management and safety management
