Measures loop resistance to identify damaged cables and bad punch-downs. Detects 10BASE-T/100BASE-TX/1000BASE-T link speed and duplex mode. Measures cable length, opens, and shorts. It provides a port ID function. The power is in your hands.If you''re responsible for installing and maintaining networks that use Power over Ethernet (PoE), make the NetPower an essential part of your toolbox.This advanced, easy-to-use handheld tester can give you the peace of mind you need to check and verify Power over Ethernet links - before you accidentally damage any equipment! You can even differentiate between IEEE standard power and manufacturer-specific power. In addition, power for devices can run over different pairs or on all pairs, and the NetPower will tell you in no time.Other test functions include tone generation for cable tracing. You can also use the tester to measure cable length and identify switch or hub ports.
