Pomya Fiber Optical Power Meter with Visual Fault Locator

1. Introduction

This manual provides detailed instructions for the safe and effective operation of your Pomya Fiber Optical Power Meter with Visual Fault Locator (OPM VFL), Model Pomyat7dpgfksex. Please read this manual thoroughly before using the device to ensure proper functionality and to prevent damage.

2. Safety Information

Observe the following safety precautions to prevent injury and damage to the device:

• Do not look directly into the optical output ports, especially when the Visual Fault Locator (VFL) is active. The laser light can cause eye damage.
• Ensure the device is powered off when not in use or during maintenance.
• Keep the device dry. Do not expose it to moisture or liquids.
• Avoid dropping the device. The silicone protective case offers some protection, but extreme impacts can cause internal damage.
• Use only specified battery types (2xAAA batteries). Do not mix old and new batteries or different battery types.

4. Setup

1. Battery Installation: Open the battery compartment cover on the back of the device. Insert two (2) AAA batteries, ensuring correct polarity (+/-). Close the battery compartment cover securely.
2. Initial Power On: Press and hold the power button ( ⑂ ) for approximately 2 seconds to turn on the device. The LCD screen will illuminate.

5. Operating Instructions

5.1. Power On/Off

• To power on: Press and hold the power button ( ⑂ ) for 2 seconds.
• To power off: Press and hold the power button ( ⑂ ) for 2 seconds. The device also features an auto shut-off function after a period of inactivity to save power.

5.2. Optical Power Measurement (OPM)

1. Ensure the device is powered on.
2. Connect the fiber optic cable to be tested to the OPM input port (typically labeled 'OPM') using the 2.5mm universal connector.
3. Select the appropriate wavelength using the wavelength button (λ). Match the wavelength of the light source being measured.
4. The measured optical power in dBm will be displayed on the LCD screen.

5.3. Visual Fault Locator (VFL)

1. Ensure the device is powered on.
2. Connect the fiber optic cable to the VFL output port (typically labeled 'VFL').
3. Press the VFL button (🔆) to activate the red laser light.
4. Observe the fiber for any light leakage, which indicates breaks, bends, or poor connections.
