Press the power button (6) and hold it for 3 seconds to turn the device on or off.

Wire mapping
This function is used to check if the wires within the cable are connected correctly. To test the network cable, plug one end of the cable into the RJ45 port (4) on the transmitter and the other end into the RJ45 port (13) on the remote unit. Select CONT (Wire mapping) in the main menu, and then press the OK button (12) to test.
Possible outcomes are shown below:

When there are many faults in the cable, the device only shows short circuit.

PoE test
This function is used to identify the pins that provide PoE, the PSE type (standard or non-standard), polarity, mode, and voltage. Insert one end of the cable or the RJ45 patch cord (included) into the PoE port (2) on the transmitter and the other end into the PoE equipment (such as network switch, router, etc). Select PoE in the main menu, and then press the OK button (12) to test.
Possible outcomes are shown below:

Power consumption test
This function is mainly used to define the power consumption by a PoE powered device. It also helps to identify the pins that provide PoE, the PSE type (standard or non-standard), polarity, mode, and voltage. Connect both PSE and PD to the two PoE ports (2) on the transmitter and select PoE in the main menu.

ERMENRICH-NP25-Netgeeks-Poe-Tester-FIG-4

Powered device (PD) test
This function is used to test the voltage, current, and power consumed by DC appliances. Connect the power adapter to the DC input (7). Then, plug one end of the DC cable (included) into the powered device and the other end into the DC output (8). Select POWER (PD test) in the main menu, and then press the OK button (12) to test.
Possible outcome is shown below:

Loop-back test
This function is used to check if the signal transmission between the network switch and the powered device is working properly. Plug one end of the cable or the RJ45 patch cord (included) into the loop-back test port (3) on the transmitter and the other end into the network switch. Select LOOP (Loop-back test) in the main menu. The device will send a signal to the network switch and wait for the response signal. If the LED on the network switch lights up and “Loop testing…” is continuously displayed on the screen, it means that the signal transmission is good. If the LED on the network switch does not light up, it means that there are problems in the communication channel.
