1. Widely used in metal wire line occasions such as telephone system, computer network, video network, optical communication engineering and so on.
2. Adopt LCD intuitive display screen, data display is clearer, POE mode, digital mode, analog mode can be switched freely.
3. POE test function: This tool can be used to test standard and non-standard POE equipment, as well as POE voltage, power supply polarity and power supply mode.
4. Voltage test function: You can click "V" to enter the voltage test function, you can measure the battery voltage and voltage polarity, and then press "V" to enter the test mode.
5. Adjustable sensitivity: when you receive a strong signal, turn down the stereo; when you receive a weak signal, please pick up the audio equipment, it can give you more accurate test data.
6. With the LED flashlight function, the flashlight can be turned on when the light is weak or used at night, so that you can use it normally in the dark environment.
