Key specifications

• Product type: PoE tester
• Operating voltage: 9V
• Colour: Black and Blue

How to use

Connect the tester to the network cable or network port you wish to check, following normal safety precautions for live network equipment. Power the unit with a compatible 9V battery, then initiate the test according to the device’s front-panel controls.
