6.1 Cable Scan (Digital/Analog/PoE Mode)

This function helps locate target cables among bundles. Connect the network cable to the RJ45 port on the main unit. Select the desired scan mode (Digital, Analog, or PoE) on the main unit. Use the receiver to trace the cable. The receiver will emit an audible tone, which intensifies as it approaches the target cable.

6.2 קאַבל קאָנטינויטי טעסט

To check for open circuits, short circuits, cross-overs, or other wiring faults in network cables:

1. Connect one end of the network cable to the 'CONT' port on the main unit.
2. Connect the other end of the cable to the 'RECEIVE' port on the receiver.
3. Select the continuity test mode on the main unit. The display will show the wiring status (e.g., open, short, cross). A green LED (G LED) indicates an STP cable.

פיגורע 6.2: Cable Continuity Test. This image illustrates the NF-918S main unit and receiver connected to an RJ45 network cable, performing a continuity test. The display shows "LINE" indicating a successful connection test.

6.3 Optical Power Meter (OPM)

To measure optical power in fiber optic cables:

1. Connect the fiber optic cable to the OPM port on the main unit.
2. Select the OPM function on the main unit.
3. Use the 'WAVE' button to cycle through the available wavelengths (850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm) to match your fiber.
4. Use the 'UNIT' button to switch between dBm, dB, mW, uW, nW.
5. The 'REF' button allows setting a reference power level for relative measurements.

6.4 וויזועלער שולד לאָקאַטאָר (VFL)

To visually identify faults in fiber optic cables:

1. Connect the fiber optic cable to the VFL port on the main unit.
2. Activate the VFL function. A strong red laser light will be emitted into the fiber.
3. Observe the fiber along its path. Breaks, bends, or poor connections will cause the red light to escape or scatter, making the fault visible.

To test Power over Ethernet (PoE) functionality:

1. Connect the network cable from the PoE source (e.g., PoE switch) to the main unit's RJ45 port.
2. Select the PoE test mode. The device will automatically identify the power supply type (middle span/end span) and whether the equipment is standard or non-standard PoE.

6.6 קאַבל לענג מעסטונג

To measure the length of various cables:

1. Connect the cable to be measured to the appropriate port on the main unit (e.g., RJ45 for network cables).
2. Select the length measurement function. The device will display the cable length up to 200m. This function supports network cables, telephone lines, and BNC cables.
