CONTINUITY TESTING
Test network cable continuity, shorted, broken, cross

CABLE SCAN Quickly trace UTP/STP cable
Widely used in engineering wiring, equipment room maintenance, equipment update and other scenarios Target cable
Digital / Analog mode
Connect the cable to be tested to "SCAN "port of transmitter to, enter " SCAN "on the main menu, press ok to choose scan mode you prefer.

POE TEST
Quickly identify PoE device
It can test the information of standard PoE device, such as POE voltage, power supply polarity, power supply mode and also the type of PSE (af or at standard ).

QC TESTING
Test whether the crystal head of the cable is ok.
Just only one-end crystal head can also tested.
Crystal head testing
Result will be updated automatically
√indicates that the cable is ok
× indicates that the cable is abnormal.

OPTICAL POWER METER
Automatic identification of fiber frequency
6 wavelengths, high precision testing

VFL FUNCTION
Fast flashing, slow flashing, and light on
10mW, high precision

NCV FUNCTION
Avoid the dangers caused by strong electricity during construction.
