Handy wiring tester with integrated length measurement and tone generator. Additionally, the device detects PoE up to Class 8, 90W (PoE++) and briefly applies power to the port to test the actual PoE voltage supply. The device features a 3.5-inch color screen with a graphical user interface and provides easily understandable test results. Its main applications include: pre-checking the wiring after installation and before final inspection with a qualifier or certifier, quick testing of patch cables for correct wiring, locating ports using the tone generator and optionally available cable tracer such as Softing CP15, diagnosing ports that provide PoE up to 90W, detecting the PoE class, and applying load to the port being tested, troubleshooting installations that use PoE.
