Versatile Network Cable Tester: This multifunctional device combines network cable testing with a multimeter for precise measurements of DC/AC current, voltage, resistance, NCV, continuity, diodes, and temperature. Ideal for engineering, network maintenance, and equipment troubleshooting, it accurately locates cables with ease. Comprehensive Cable Toner: Offering a range of essential functions including POE testing, anti-jamming for RJ45 CAT5/CAT6 cables, continuity testing, voltage measurement, port flashing, sensitivity adjustment, cable length testing, and a built-in LED flashlight, this tool ensures efficient network diagnostics. Portable TDR Cable Length Tester: Featuring Time Domain Reflectometry (TDR) technology, this tester provides portable and accurate cable length measurements, calibrates Velocity of Propagation (VoP) values, and swiftly identifies faults in cables, making on-site troubleshooting convenient and effective. Efficient POE Testing & Port Identification: Streamline the identification of PoE devices with the POE tester, which assesses PoE voltage, power supply polarity, and mode, along with detecting PSE type (af or at standard). Port Flashing functionality aids in quick identification of connected ports on network switches or routers. Safety-focused NCV Detection: This network cable tester with multimeter incorporates Non-contact Voltage (NCV) detection, ensuring safety by identifying voltage presence without physical contact with the cable. With intelligent recognition of measurement objects and protection against accidental electric shocks, it prevents damage to connected devices even at 250V, enhancing safety during testing operations.
