5. ترتیب کول
5.1 د بیټرۍ نصب کول
- د وسیلې په شا کې د بیټرۍ د برخې پوښ ومومئ.
- د خلاصولو لپاره یې پوښ سلائډ یا خلاص کړئ.
- درې (3) 1.5V AAA بیټرۍ دننه کړئ، د سم قطبیت (+/-) ډاډ ترلاسه کړئ لکه څنګه چې د خونې دننه ښودل شوي.
- د بیټرۍ کمپارټ پوښ په خوندي ډول بدل کړئ.
5.2 ابتدايي پاور آن
فشار ورکړئ او ونیسئ ځواک button to turn on the device. The LCD display will illuminate, showing the current mode and settings.
6. عملیاتي لارښوونې
6.1 Optical Power Meter Mode
This mode measures the absolute optical power or relative loss in optical fiber networks.
- Connect Fiber: Connect the optical fiber to be tested to the Power Meter input port. Ensure the connector is clean.
- د طول موج غوره کړئ: فشار ورکړئ λ button to cycle through the available calibrated wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm. Select the wavelength matching your light source.
- View اندازه کول: The display will show the optical power in dBm.
- Change Unit: فشار ورکړئ dBm/W button to switch between dBm and W (Watts) units.
- Set Reference (REF): For relative measurements (loss), connect a known good fiber to a stable light source and the power meter. Press the REF button to set the current power reading as the reference (0dB). Subsequent measurements will show the loss relative to this reference.
- Frequency Identification: The power meter can identify modulation frequencies from 10Hz to 60KHz. If the incoming signal is modulated, the frequency will be displayed.
6.2 Optical Light Source Mode
This mode provides a stable optical signal for testing fiber optic cables.
- Connect Fiber: Connect the optical fiber to be tested to the Light Source output port. Ensure the connector is clean.
- د طول موج غوره کړئ: فشار ورکړئ λ button to cycle through the available wavelengths: 1310nm and 1550nm. Select the desired wavelength.
- Select Modulation Frequency: فشار ورکړئ Hz button to cycle through modulation frequencies: 270Hz, 1KHz, 2KHz, or continuous wave (CW).
- د محصول سیګنال: The device will emit a stable optical signal at the selected wavelength and modulation.
6.3 د اتومات بند فعالیت
