4. Орнотуу

4.1 Таңгактан чыгаруу жана текшерүү

Carefully unpack the AUA280U OTDR and all accessories. Verify that all items listed in the package contents are present and undamaged. If any items are missing or damaged, contact your supplier immediately.

4.2 Батареяны заряддоо

1. Берилген кубат адаптерин түзмөктөгү кубаттоо портуна туташтырыңыз.
2. Plug the power adapter into a standard electrical outlet (100-240V).
3. The charging indicator light will illuminate. Allow the device to charge fully before first use. A full charge typically takes several hours.

4.3 Күйгүзүү/өчүрүү

• To power on: Press and hold the Power Off button until the screen illuminates.
• To power off: Press and hold the Power Off button until the shutdown prompt appears, then confirm.

5. Иштөө нускамалары

The AUA280U features a touch screen interface for easy navigation. Alternatively, the physical buttons can be used.

5.1 OTDR Function

The OTDR function is used for measuring fiber length, identifying breaks, and analyzing optical network performance.

1. From the main menu, tap the 'OTDR' icon or press the corresponding soft key.
2. Connect the fiber optic cable to be tested to the OTDR port using the appropriate connector (e.g., FC/UPC, SC/UPC). Ensure connectors are clean.
3. Select the desired wavelength (e.g., 1310nm, 1550nm) and measurement parameters (e.g., range, pulse width) from the settings menu.
4. Initiate the test. The OTDR trace will be displayed on the screen, showing events like splices, connectors, and fiber ends.
5. Analyze the trace for event locations, loss, and reflection. The device software allows for further data analysis and report generation.

5.2 Visual Fault Locator (VFL) функциясы

The VFL emits a visible red laser light to quickly locate breaks, bends, or poor connections in fiber optic cables over short distances.

1. From the main menu, tap the 'VFL' icon or press the corresponding soft key.
2. Connect the fiber optic cable to the VFL port.
3. Select the desired mode (CW for continuous wave, 1Hz or 2Hz for flashing).
4. Activate the VFL. Observe the fiber for any visible red light leakage, indicating a fault.
5. Абайлаңыз: Avoid direct eye exposure to the VFL laser light.

5.3 Optical Power Meter (OPM) Function

The OPM measures the absolute or relative optical power in a fiber optic link.

1. From the main menu, tap the 'OPM' icon or press the corresponding soft key.
2. Connect the fiber optic cable from the light source to the OPM port.
3. Select the appropriate wavelength for measurement (e.g., 1310nm, 1550nm).
4. The measured optical power (in dBm) will be displayed on the screen.

5.4 Optical Light Source (OLS) Function

The OLS provides a stable optical signal at specific wavelengths for testing fiber optic cables in conjunction with an OPM.

1. From the main menu, tap the 'OLS' icon or press the corresponding soft key.
2. Connect the fiber optic cable to the OLS port.
3. Select the desired output wavelength (e.g., 1310nm, 1550nm).
4. The OLS will emit a stable light signal. This can be used with an external OPM to measure insertion loss.

5.5 Маалыматтарды башкаруу

The AUA280U can store up to 200 groups of data. Use the 'File' menu to save, review, or delete measurement results. Data can be transferred to a computer via the USB interface for further analysis using the provided software.
