5. Operating Instructions

5.1 Navigating the Interface

The KP800 features a 4.3-inch touch screen for easy navigation. You can also use the physical buttons:

• OK: Confirm selection or enter a menu.
• SETUP: Access settings for the current function.
• ESC: Go back to the previous screen or exit a function.
• M/A/Arrow Buttons: Navigate through menus and adjust parameters.

5.2 OTDR Function

The OTDR function is used for measuring fiber length, locating breakpoints, and analyzing signal attenuation. It supports an optional active fiber test.

1. From the main menu, tap on the 'OTDR' icon.
2. Connect the fiber optic cable to the OTDR/LS port using the appropriate SC or FC adapter.
3. In the OTDR settings, configure parameters such as wavelength (e.g., 1310nm, 1550nm), pulse width, and measurement range according to your testing requirements.
4. Initiate the test. The device will perform automatic measurement and analysis, displaying the trace graph and event list.
5. For active fiber testing, ensure the 'Active Fiber Test' option is enabled in the settings (if available for your model).

5.3 OPM (Optical Power Meter) and VFL (Visual Fault Locator)

These functions are crucial for measuring optical power and visually locating fiber faults.

1. From the main menu, tap on the 'OPM' or 'VFL' icon.
2. For OPM: Connect the fiber to the OPM port. Select the desired calibration wavelength (e.g., 1310nm, 1550nm). The device will display the optical power in dBm.
3. For VFL: Connect the fiber to the VFL port. Activate the VFL function. A red laser light will be emitted, allowing you to visually identify breaks, bends, or poor connections in the fiber up to 10km.

5.4 LS (Laser Source) Function

The LS function provides a stable light source for various fiber optic tests.

1. From the main menu, tap on the 'Laser Source' icon.
2. Connect the fiber to the OTDR/LS port.
3. Select the desired output wavelength (consistent with OTDR) and modulation mode (CW, 270Hz, 330Hz, 1KHz, 2KHz).
4. WARNING: This device uses a Class 3B laser. Avoid direct eye exposure to the laser beam, as it can cause severe eye injury. Always use appropriate safety precautions.

5.5 RJ45 Network Test

The KP800 can test the line sequence and length of RJ45 network cables.

1. From the main menu, tap on the 'RJ45 Test' or 'RJ45 Tracker' icon.
2. Connect one end of the network cable to the RJ45 Network testing port on the KP800.
3. Connect the other end of the network cable to the RJ45 remote adapter, and then connect the RJ45 receiver to the remote adapter.
4. Initiate the test. The device will display the wiring sequence and cable length.

6. Maintenance

6.1 Cleaning Optical Ports and Connectors

Regular cleaning of optical ports and connectors is essential for accurate measurements and to prevent damage. Use only lint-free optical cleaning wipes and approved optical cleaning solutions. Never use abrasive materials or solvents.

6.2 Battery Care

To maximize battery life, charge the device regularly and avoid completely draining the battery. If storing the device for an extended period, ensure it is charged to approximately 50% and recharge every few months.

7. Troubleshooting

• Device not powering on: Ensure the battery is charged. Connect the device to the charger and try again.
• Inaccurate fiber optic measurements: Clean all fiber optic connectors and ports thoroughly. Verify that the correct wavelength and pulse width settings are selected for the fiber type being tested.
• No VFL light: Check if the VFL function is activated in the menu. Ensure the fiber is properly connected to the VFL port.
• RJ45 network test failure: Confirm that the network cable is correctly connected to both the KP800's RJ45 port and the remote adapter/receiver. Check for cable damage.
• Touch screen unresponsive: Try restarting the device. If the issue persists, contact support.
