5. Setup

Follow these steps to prepare your SKYSHL SS304T-2A1 for first use.

5.1 Charging the Battery

1. Connect the provided USB Type-C cable to the device's USB port (located under the protective cover on the top).
2. Connect the other end of the USB cable to the power adapter.
3. Plug the power adapter into a standard electrical outlet.
4. The 'CHARGE' indicator light on the device will illuminate during charging. A full charge typically takes several hours.

5.2 Powering On/Off

• To Power On: Press and hold the red power button (ⓔ) until the screen illuminates.
• To Power Off: Press and hold the red power button (ⓔ) until the shutdown prompt appears, then confirm.

5.3 Initial Configuration

Upon first power-on or after a factory reset, you may need to configure basic settings.

1. Language Selection: Navigate to the 'System' menu and select your preferred language (English, Russian, Spanish, French, Portuguese).
2. Date and Time: Set the correct date and time in the 'System' settings.
3. Screen Brightness: Adjust the display brightness for optimal visibility.

6. Operating Instructions

The SS304T-2A1 offers a main interface with various function icons. Use the touchscreen or the navigation buttons to select the desired function.

6.1 OTDR Function (Optical Time Domain Reflectometer)

The OTDR function is used to characterize fiber optic links, measure length, attenuation, and locate events like splices, connectors, and breaks.

1. Connect Fiber: Clean the fiber connector end-face thoroughly. Connect the fiber under test to the OTDR port using the appropriate adapter (SC/UPC or FC/UPC provided).
2. Select OTDR Mode: From the main interface, select 'Auto OTDR' for simplified testing or 'Expert OTDR' for advanced parameter configuration.
3. Configure Parameters (Expert OTDR): If using Expert OTDR, set parameters such as wavelength (1310nm or 1550nm), pulse width, range, and measurement time. For Auto OTDR, the device will automatically select optimal parameters.
4. Start Test: Press the 'Start' button to begin the OTDR measurement. The device will display the trace curve and event list.
5. Analyze Results: Review the displayed curve and event map. The event map graphically represents events along the fiber, while the list provides detailed numerical data for each event (distance, loss, reflectance).

6.2 OPM Function (Optical Power Meter)

The OPM measures the optical power of a fiber optic signal.

1. Connect Fiber: Clean the fiber connector and connect it to the OPM port using the 2.5mm universal interface.
2. Select OPM: From the main interface, select the 'OPM' icon.
3. Measure Power: The device will display the optical power in dBm or mW. You can select the measurement wavelength if needed.

6.3 OLS Function (Optical Light Source)

The OLS emits a stable optical signal for loss measurement or continuity testing.

1. Connect Fiber: Clean the fiber connector and connect it to the OLS port (shared with OTDR port).
2. Select Laser Source: From the main interface, select the 'Laser Source' icon.
3. Configure Wavelength: Select the desired output wavelength (1310nm or 1550nm).
4. Activate Source: Turn on the laser source. The device will emit a continuous wave.

6.4 VFL Function (Visual Fault Locator)

The VFL emits a visible red laser to locate breaks, bends, or poor connections in short fiber segments.

1. Connect Fiber: Clean the fiber connector and connect it to the VFL port using the 2.5mm universal interface.
2. Select VFL: From the main interface, select the 'VFL' icon.
3. Activate VFL: Turn on the VFL. A red light will be emitted. Observe the fiber for any visible light leakage, which indicates a fault.

6.5 RJ45 Cable Tracker

The RJ45 Cable Tracker is used to identify and locate network cables.

1. Connect Cable: Connect one end of the RJ45 cable to the LAN1 or LAN2 port on the main unit. Connect the other end to the remote tracker unit.
2. Select RJ45 Tracking: From the main interface, select the 'RJ45 Tracking' icon.
3. Start Tracking: Activate the tracking function. The remote unit will emit a signal, allowing you to trace the cable.

6.6 Optical Loss Test

This function measures the total optical loss of a fiber link.

1. Connect Reference: Connect a known good fiber patch cord from the OLS port to the OPM port to establish a reference power level.
2. Set Reference: In the 'Loss Test' menu, set the reference power.
3. Connect Fiber Under Test: Disconnect the OPM from the OLS. Connect the fiber link to be tested between the OLS and OPM ports.
4. Measure Loss: The device will display the optical loss of the connected fiber link.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your SKYSHL SS304T-2A1.

• Cleaning Optical Ports: Always clean fiber optic connectors and adapters before use. Use lint-free wipes and optical-grade alcohol. Never use abrasive materials.
