5.1 بیٹری کی تنصیب
- ڈیوائس کے پچھلے حصے میں بیٹری کے کمپارٹمنٹ کور کو تلاش کریں۔
- Slide or unclip the cover to open it.
- تین (3) 1.5V AAA بیٹریاں داخل کریں، صحیح قطبیت (+/-) کو یقینی بناتے ہوئے جیسا کہ کمپارٹمنٹ کے اندر اشارہ کیا گیا ہے۔
- بیٹری کے کمپارٹمنٹ کور کو محفوظ طریقے سے تبدیل کریں۔
5.2 ابتدائی پاور آن
دبائیں اور تھامیں۔ طاقت button to turn on the device. The LCD display will illuminate, showing the current mode and settings.
6. آپریٹنگ ہدایات
6.1 Optical Power Meter Mode
This mode measures the absolute optical power or relative loss in optical fiber networks.
- فائبر کو جوڑیں: Connect the optical fiber to be tested to the Power Meter input port. Ensure the connector is clean.
- طول موج کا انتخاب کریں: دبائیں λ button to cycle through the available calibrated wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm. Select the wavelength matching your light source.
- View پیمائش: The display will show the optical power in dBm.
- Change Unit: دبائیں 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.
- فائبر کو جوڑیں: Connect the optical fiber to be tested to the Light Source output port. Ensure the connector is clean.
- طول موج کا انتخاب کریں: دبائیں λ button to cycle through the available wavelengths: 1310nm and 1550nm. Select the desired wavelength.
- Select Modulation Frequency: دبائیں Hz button to cycle through modulation frequencies: 270Hz, 1KHz, 2KHz, or continuous wave (CW).
- آؤٹ پٹ سگنل: The device will emit a stable optical signal at the selected wavelength and modulation.
6.3 آٹو آف فنکشن
The device features an auto-off function to conserve battery life. If no operation is performed for approximately 15 minutes, the device will automatically power off. Press the طاقت اسے دوبارہ آن کرنے کے لیے بٹن۔
7 دیکھ بھال
- Cleaning Optical Connectors: Always ensure optical connectors are clean before use. Use lint-free wipes and appropriate optical cleaning solutions. Dirty connectors can lead to inaccurate measurements and damage to the device or fiber.
- بیٹری کی تبدیلی: When the battery indicator on the display shows low power, replace all three 1.5V AAA batteries promptly.
- ذخیرہ: When not in use, store the device in a dry, cool place, away from direct sunlight and extreme temperatures. Always replace the protective caps on the optical ports to prevent dust and damage.
- بیرونی صفائی: آلے کے بیرونی حصے کو نرم سے صاف کریں، ڈیamp کپڑا کھرچنے والے کلینر یا سالوینٹس کا استعمال نہ کریں۔
