- Ensure the fiber optic cable connector is clean. Use a fiber optic cleaning tool if necessary.
- Insert the fiber optic connector (FC, SC, or ST) into the 2.5mm standard interface receiver port at the top of the power meter. Ensure a snug fit.
5.2 Selecting Wavelength

Press the Λ Button repeatedly to cycle through the available wavelengths (850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm). Select the wavelength that matches the optical signal you are measuring.
5.3 Taking a Measurement
- Connect the fiber optic cable to the receiver port.
- Select the correct wavelength using the Λ Button.
- The optical power measurement will be displayed on the LCD screen in dBm or dB/W.
- Press the dB Button to switch between dBm and dB/W units if desired.
5.4 Using the ZERO Function
The ZERO Button allows you to set a reference power level. This is useful for relative power measurements (e.g., measuring loss). To use:
- Connect a known good fiber optic signal to the power meter.
- Press the ZERO Button. The display will show '0.00dB' or similar, indicating the current power level is now the reference.
- Any subsequent measurements will be displayed relative to this reference.
5.5 Backlight and Auto-Off
- Press the LIGHT Button to turn the display backlight ON or OFF.
- Press the AUTO OFF Button to activate or deactivate the automatic shutdown feature, which conserves battery life.

6. Maintenance
6.1 Cleaning
- Keep the device clean and free from dust. Use a soft, dry cloth for cleaning the exterior.
- Regularly clean the optical receiver port using specialized fiber optic cleaning tools to ensure accurate measurements. Dust or debris in the port can significantly affect readings.
6.2 Storage
- When not in use for extended periods, remove the batteries to prevent leakage and damage to the device.
- Store the power meter in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
7.1 No Power
- Check if the batteries are correctly installed with the right polarity.
- Replace old or depleted batteries with new AA batteries.
- Ensure the power button is pressed and held sufficiently to turn on the device.
7.2 Inaccurate Readings
- Verify that the selected wavelength on the power meter matches the wavelength of the optical signal being tested.
- Clean the fiber optic connector and the power meter's receiver port. Contamination is a common cause of inaccurate readings.
- Ensure the fiber optic cable is properly seated in the receiver port.
- If using the ZERO function, ensure the reference point was set correctly.
7.3 Display Issues
- If the display is dim, activate the backlight using the LIGHT Button.
- If the display is blank or shows erratic characters, try replacing the batteries.
