## Features

- 1. NF-488 is a multifunctional tester for detecting POE, network cables, and Ethernet. It is mainly used for the installation of weak current systems such as security monitoring, communication lines, and comprehensive cabling, reducing network cable testing and troubleshooting time for people with testing needs.
- 2. NF-488 has two main testing functions: POE switch testing and POE power testing. It can automatically identify standard/non-standard POE information, including af/at voltage standards, power supply polarity, and jumper methods. The voltage test range is 0-60V.
- 3. It has remote wiring function and can test the open circuit, short circuit, and crossover status in the network cable. Measurable shielded wire. The LCD backlit large screen is clear and visible, and the concise display interface makes the result data clear at a glance.
- 4. It can be used for power testing function, which can test DC power, as well as test the voltage, current, and power between the power adapter and the electrical equipment. And circuit testing function, testing whether the network cable circuit connected to the switch is working properly.
- 5. High end humanized design details, independently set backlight/shutdown time, the shell has anti slip effect, and the lighting can solve the problem of unclear visibility during dark area operations.
