2. Safety Information

Please read and understand all safety warnings and operating instructions before using this device. Failure to follow these instructions may result in injury or damage to the device.

2.1 Laser Safety Warning

The UT693A-C01 contains a Visual Fault Locator (VFL) that emits a 650nm red laser. This is a Class IIIA laser product. Direct exposure to the laser beam can cause eye damage.

• WARNING: Laser radiation. Do not look directly into the beam. Avoid close contact.
• Never look directly into the optical output port when the VFL is active.
• Do not point the laser at people or animals.
• Use caution when working with fiber optic cables, as broken fibers can be sharp.

4.3 Powering On/Off

• To power on the device, press and hold the ON/OFF button for approximately 2 seconds.
• To power off the device, press and hold the ON/OFF button for approximately 2 seconds until the display turns off.

5. Operating Instructions

5.1 Optical Power Measurement

The optical power meter function measures the power of optical signals in fiber optic networks.

1. Ensure the device is powered on.
2. Connect the fiber optic cable to the optical power meter input port. The UT693A-C01 supports 2.5mm universal connectors (FC/SC/ST).
3. Press the Wavelength button to cycle through the available calibration wavelengths (850nm, 980nm, 1270nm, 1300nm, 1310nm, 1490nm, 1550nm, 1577nm, 1625nm, 1650nm) until the desired wavelength is displayed.
4. The measured optical power will be displayed on the screen in dBm, dB, mW, or uW.
5. To set a reference value (REF), press and hold the REF button. This allows for relative power measurements.

5.2 Visual Fault Locator (VFL)

The VFL function helps locate breaks, bends, and poor connections in fiber optic cables by emitting a bright red laser light.

1. Ensure the device is powered on.
2. Connect the fiber optic cable to the VFL output port.
3. Press the VFL button to activate the red laser.
4. Press the VFL button again to switch between continuous wave (CW) mode and flashing mode.
5. Observe the fiber for any visible red light leakage, which indicates a fault.
6. Press the VFL button once more to turn off the VFL.

5.3 RJ45 Network Cable Sequence Test

This function verifies the correct wiring sequence of RJ45 network cables.

1. Ensure the device is powered on.
2. Connect one end of the RJ45 network cable to the RJ45 port on the UT693A-C01.
3. The device will automatically begin testing the cable sequence.
4. The display will show the wiring status, indicating if the cable is correctly wired (e.g., 1-8 sequence) or if there are any open circuits, shorts, or cross-overs.
