100V Voltage-resis Anti-burnout
Ultra-high voltage-resistant circuit design ensures safety and allows operation under voltages below 100V.Using digital signals, it can operate normally even in high-interference environments.

Switch Port Flashing Function
By plugging one end into the switch and the other into the network cable tester, this function triggers the switch's port LED to flash, enabling rapid identification of the corresponding RJ45 cable.

Auto Tracing and Testing Switching
Once the cable is traced, there is no need to switch the transmitter to testing mode. Simply plug the other end into the testing port to immediately perform wire alignment testing, which significantly improves work efficiency.

RJ45 Connector Crimping Test
After crimping the RJ45 connector, simply insert it into the crimping detection port to quickly check if the crimping is accurate.

Non-contact Voltage Testing
Supports non-contact voltage testing for live cables with AC 50/60Hz over 70V, avoiding electric shock risks and enabling quick target location.

Use alligator clips to clamp both ends of the power supply under test, then insert into the RJ11 port for testing
