4. Setup

4.1 Unpacking and Initial Inspection

Upon receiving your NF-916, carefully unpack all components and inspect for any signs of damage. The package should include the main unit (transmitter), a remote unit, a USB Type-C cable, and this user manual.

Figure 4.1: NF-916 Product and Packaging. The image displays the NF-916 device alongside its retail box, highlighting its multi-functionality as an Optical Fiber Tester, Network Cable Tester, RJ45 Cable Tester, CAT5/CAT6/CAT3 tester, and VFL.

4.2 Charging the Device

Before first use, fully charge the NF-916 using the provided USB Type-C cable. Connect the cable to the Type-C charging port on the side of the device and to a standard USB power source (e.g., computer USB port, wall adapter).

5. Operating Instructions

5.1 Optical Power Meter (OPM) Function

The OPM function measures the optical power of fiber optic signals.

1. Power on the NF-916.
2. Connect the fiber optic cable to the OPM interface (labeled OPM) on the top of the device. The NF-916 supports FC/SC/ST universal interfaces.
3. Press the WAVE button to cycle through the supported wavelengths (850nm, 980nm, 1310nm, 1490nm, 1550nm, 1625nm) to match your testing requirements.
4. The measured optical power in dBm will be displayed on the screen.
5. Use the REF button to set a reference value for relative power measurements.

Figure 5.1: Optical Power Measurement. This image shows the NF-916 display during an OPM test, indicating the wavelength (e.g., 1310nm) and the measured power level. It also lists the six supported wavelengths: 850nm, 980nm, 1310nm, 1490nm, 1550nm, and 1625nm.

5.2 Visual Fault Locator (VFL) Function

The VFL function uses a red laser to identify breaks, bends, or poor connections in fiber optic cables.

1. Power on the NF-916.
2. Connect the fiber optic cable to the VFL interface (labeled VFL) on the top of the device.
3. Press the VFL/Lamp button repeatedly to cycle through the VFL modes: Steady On, Slow Flashing, and Fast Flashing.
4. Observe the fiber for red light leakage, which indicates a fault.

5.3 RJ45 Network Cable Test (Continuity & QC)

This function tests the continuity and crimping quality of RJ45 network cables (CAT5, CAT6) and RJ11 cables.

1. Detach the remote unit from the main NF-916 device by pressing the release button on the back.
2. Connect one end of the network cable to the RJ45 port on the main unit and the other end to the RJ45 port on the remote unit.
3. The screen on the main unit will display the continuity test results, showing which wires are correctly connected.
4. For crimp quality check (QC function), connect a single-ended RJ45 plug to the main unit's RJ45 port. The device will automatically verify the crimping accuracy.

Figure 5.3: RJ45 Network Test Setup. This image illustrates the split design of the NF-916, with the main unit connected to one end of an RJ45 cable and the detachable remote unit connected to the other end, demonstrating its use for network cable testing.

Figure 5.4: Single-Ended RJ45 Crimping Test. The image shows the NF-916 performing a crimping test on a single RJ45 connector, with the display indicating the status of each wire, ensuring correct crimp quality.

5.4 Wire Tracing Function

The wire tracing function helps locate specific cables within a bundle or wall.

1. Connect the network cable to the main unit.
2. Activate the wire tracing mode (refer to device interface for specific button/menu option, usually integrated with continuity test).
3. Use the remote unit or a compatible probe (not included) to trace the cable. The device will emit a signal that can be detected by the probe, helping to identify the correct cable.

5.5 Integrated LED Flashlight

To activate the high-brightness LED flashlight, press the VFL/Lamp button briefly when the VFL is off. Press again to turn off.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. For optical interfaces, use specialized fiber optic cleaning tools.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided carrying case for protection.
• Battery Care: To prolong battery life, avoid fully discharging the battery frequently. If storing for extended periods, charge the battery to about 50% every few months.
• Interface Protection: Always keep the protective caps on the OPM and VFL interfaces when not in use to prevent dust and damage.
