Specifications

Setup

Charging the Device

Before first use, ensure both the transmitter and receiver are fully charged using the provided USB cable. Connect the USB cable to the charging port on each unit and to a suitable USB power source. The battery indicator on the display will show charging status.

Powering On/Off

Press and hold the power button on both the transmitter and receiver to turn them on or off. The display will illuminate upon activation.

Connecting the Transmitter

For tracing wires, connect the transmitter to the circuit or cable you wish to trace. Use the provided test leads to connect the transmitter's positive and negative electrode interfaces to the target wire and a ground point, respectively.

Operating Instructions

Underground Cable Detection

1. Connect the transmitter to the cable to be traced and a suitable ground.
2. Turn on both the transmitter and receiver.
3. Select the appropriate mode (Auto or Manual) on the receiver. The display shows signal strength and level.

4. Move the receiver over the area where the cable is suspected. The signal strength indicator and audible tone will guide you to the cable's location and depth.
5. Note: The maximum test length and depth may vary depending on soil type and environmental conditions.

In-Wall Cable and Pipe Detection

The U630 can also detect cables and pipes hidden within walls.

1. Ensure the transmitter is connected to the target line.
2. Use the receiver to scan the wall surface. The signal strength will increase as you approach the hidden cable or pipe.

Non-Contact Voltage (NCV) Test

The NCV function allows for quick detection of live AC voltage without direct contact.

1. Press the NCV button on the receiver.
2. Bring the probe tip close to the suspected live wire or outlet.
3. The device will indicate the presence of AC voltage through an audible alarm and visual indicator on the display.

AC/DC Voltage Measurement

The U630 can measure AC/DC voltages between 12V and 400V.

1. Connect the test leads to the positive and negative electrode interfaces on the transmitter.
2. Connect the other ends of the test leads to the circuit or component where you want to measure voltage.
3. The voltage reading will be displayed on the screen.

Using the LED Flashlight

Press the flashlight button on the receiver to activate the built-in LED flashlight for illumination in dark working environments.

Maintenance

Care and Storage

• Clean the device regularly with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Store the device in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.
• Ensure the device is fully charged before long-term storage to preserve battery life.
• Inspect test leads for damage before each use and replace if necessary.

Troubleshooting

No Signal or Weak Signal

• Check Battery: Ensure both transmitter and receiver are fully charged.
• Transmitter Connection: Verify the transmitter is correctly connected to the target cable and a good ground.
• Distance/Depth: The signal strength decreases with distance and depth. Move the receiver closer to the suspected cable path.
• Soil Type: Certain soil types (e.g., very wet or highly conductive) can affect detection depth and accuracy.
• Interference: Other electrical fields or metal objects nearby can cause interference. Try to minimize these.

Inaccurate Readings

• Calibration: Ensure the device is operating in the correct mode (Auto/Manual) for the task.
• Environmental Factors: High moisture or dense materials can affect accuracy.

Device Not Powering On

• Battery Level: Charge the device completely.
• Power Button: Ensure the power button is pressed and held sufficiently.
