The portable cable tester is mainly designed for on-site wire harness repair, maintenance, testing and other work. It is equipped with a built-in lithium battery and computer, and can work continuouslyMore than 8 hours. It can quickly perform tests such as short circuit breaking and insulation resistance of cables. Its mobile and portable characteristics are very suitable for on-site repair, maintenance, testing and other work of cable harness equipment.
Overview of the main functions of the product
lSelf learning testing function: detecting the connection relationship and precise resistance value of unknown cable harnesses;
lConduction function: Chaotic connection relationships caused by wire routing, short circuits, open circuits, misplaced pins, poor connections, etc; Equipped with four line testing function, making the conductivity test resistance more accurate;
lInsulation testing function: Automatically complete multi-point insulation testing, with adjustable boost time and testing time, and programmable increasing test voltage; Quickly test the insulation resistance between wires and between wires and shells;
lVoltage withstand test function: Automatically complete multi-point voltage withstand tests, with adjustable boost time and test time, and programmable increasing test voltage; Quickly test the leakage current between wires and between wires and the shell;
lUnique line number testing function: auxiliary assembly, can quickly find accurate line sequence and line number of nodes;
lElectronic component testing function: complete the testing of diodes and resistors;
