ERMENRICH-NP30-Network-Cable-Tester-fig-4

Plug one end of the testing cable (min. 10m) with a known length into the Length/Flash port (11) on the transmitter and leave the other cable end disconnected.
Select Setup (Settings) in the main menu, select Unit (Unit of measurement), and then select Calibration (Calibration) and press the PAIR&L button (4).

For more precise results, it is recommended to calibrate the device on a cable with a known length from the same manufacturer.

Using

Plug one end of the testing into the Length/Flash port (11) on the transmitter and leave the other cable end disconnected.
Select Pair/Length (Twisted pair test and Cable length measurement) in the main menu and press the PAIR&L button (4).

Possible outcome is shown below:

Port Flash function

This function is used to locate an exact port on a network switch or on a router to which the tested cable is connected.

The circle on the display will flash with the same frequency as the LED of the target port on the PoE source equipment, and different from the other LEDs.

Polarity test

This function is used to define the polarity of wires.

Plug the wire with the alligator clips into the RJ11 SCAN port (9) on the transmitter and clamp the alligator clips to the wires of the telephone cable (+ means anode and – means cathode regardless of the red and black clips clamped on the wires). The other end of the telephone cable is connected to a telephone.
Select Polar test (Polarity test) and press the PAIR&L button (4).

Possible outcome is shown below:

Cable Tracing

This function is used to locate the target cable in a cable bundle.

Shift the two-position switch (2) on the transmitter to the SCAN position to enable the cable tracing mode.
Plug a loose end of the testing cable into the corresponding port on the transmitter: RJ45 SCAN (14) for a network cable, RJ11 SCAN port (9) for a telephone cable, BNC-connector (10) for a coaxial cable, and USB SCAN port (7) for a USB-cable.
Press the Scan button (20) on the receiver to start a cable search.
Place the receiver near the cable bundle and move the receiver along the cable to trace it. When the sensor is in the close proximity to the target cable, the receiver will emit a beeping sound. To detect the cable more accurately, lower the sensitivity. The closer the device is to the object, the louder the signal will be.

Attention

Never insert a telephone cable into the RJ45 port, as it may cause damage to the cable tester.
Cable length measurement and wire mapping is impossible in the cable tracing mode.
