1. Introduction and Overview
The Leica DD130 Underground Utility and Cable Locator is designed for efficient and accurate detection of buried utilities. This package includes the DD130 Locator and the DA175 Signal Transmitter, providing a comprehensive solution for locating underground power, water, gas, and communication lines.
Key features include:
- Extended trace range with additional low frequencies (512Hz and 640Hz) for long-range locates.
- Automatic pinpointing capabilities.
- Built-in self-check for ensuring correct unit functionality.
- Signal Strength Indication (SSI) for easy cable identification.
- Hazard Zone alert for shallow services.
- IP54 rating for dust and water resistance.
2. Safety Information
WARNING: The Leica Carry Case included in this package can expose you to chemicals including DI(2-ethylhexyl)phthalate (DEHP), which is known to the State of California to cause birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov.
Always prioritize safety when operating the DD130 locator. Before commencing any excavation or ground-breaking activities, ensure all utilities are accurately located and marked. Failure to do so can result in serious injury, property damage, or service disruption.
- Always wear appropriate personal protective equipment (PPE).
- Be aware of your surroundings and potential hazards.
- Do not operate the equipment if it appears damaged or malfunctioning.
- Consult local regulations and utility companies for specific guidelines on utility locating and excavation.
- Pay close attention to the Hazard Zone alert, which indicates shallow services.

4. Setup
4.1. Battery Installation
The DD130 locator and DA175 transmitter require batteries for operation. Both units use Alkaline battery cells. Ensure fresh batteries are installed before use.
- Locate the battery compartment on the DD130 locator and DA175 transmitter.
- Open the compartment cover.
- Insert the required number of Alkaline batteries, observing the correct polarity (+/-).
- Securely close the battery compartment cover.
4.2. Initial Power-On and Self-Check
Upon powering on the DD130, the unit performs a built-in self-check to ensure proper functionality. This health check is performed each time the unit is turned on.
- Press and hold the power button on the DD130 locator.
- Observe the display for the self-check sequence.
- If any errors are indicated, refer to the Troubleshooting section.
5. Operating Instructions
The DD130 offers various modes and frequencies to effectively locate different types of underground utilities.
5.1. Operating Modes
The DD130 features Power, Radio, and Auto modes for different locating scenarios:
- Power Mode: Detects electromagnetic fields radiated by live power cables.
- Radio Mode: Detects re-radiated radio signals present on metallic utilities.
- Auto Mode: Automatically selects the best frequency for detection, combining aspects of Power and Radio modes.
5.2. Frequencies
The DD130 operates on multiple frequencies to optimize detection for various utilities and conditions:
- 8 kHz and 33 kHz: Standard frequencies for general utility locating.
- 512 Hz and 640 Hz: Low frequencies used for long-range locates, particularly effective with the DA175 Signal Transmitter.
5.3. Using the DA175 Signal Transmitter
The DA175 Signal Transmitter is used to apply a traceable signal to non-energized metallic utilities, enhancing detection accuracy and depth capabilities.
- Connect the DA175 to the utility using direct connection leads, an induction clamp, or by inducing a signal into the ground.
- Select the desired frequency on the DA175 (e.g., 512Hz or 640Hz for long range).
- Turn on the DA175.
- Use the DD130 locator in the corresponding frequency mode to trace the signal.
5.4. Locating Utilities
To locate a utility, sweep the DD130 locator across the area in the selected mode. The Signal Strength Indication (SSI) provides a numeric readout to help identify the cable and its position. The locator can pinpoint utilities at depths up to 33 feet (when used with a Sonde, not included).
5.5. Hazard Zone Alert
The DD130 features a Hazard Zone alert that warns the user of shallow services within a few feet of the locator. This safety feature is crucial for preventing accidental cable strikes. Always heed this warning and adjust your excavation methods accordingly.
6. Maintenance
Proper maintenance ensures the longevity and accuracy of your Leica DD130 locator and DA175 transmitter.
- Cleaning: Wipe down the units with a damp cloth after use. Avoid abrasive cleaners or solvents.
- Storage: Store the equipment in the provided carry bag in a dry, temperate environment when not in use.
- Battery Care: Remove batteries if the units will not be used for an extended period to prevent leakage.
- Self-Check: The built-in self-check performed at startup helps monitor the unit's health. If it indicates an issue, refer to the Troubleshooting section or contact support.
- Environmental Protection: The IP54 rating protects against dust and water splashes, but avoid submerging the units or exposing them to heavy rain for prolonged periods.
7. Troubleshooting
This section addresses common issues you might encounter with your Leica DD130 system.
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | Dead or incorrectly installed batteries. | Check battery polarity and replace with fresh Alkaline batteries. |
| No signal detected. | Incorrect mode/frequency selection; utility not conductive; transmitter not active or improperly connected. | Ensure correct mode (Power, Radio, Auto) and frequency are selected. Verify DA175 is on and properly connected to the utility. Confirm the utility is metallic and capable of carrying a signal. |
| Inaccurate depth readings. | Interference from other utilities; incorrect operating technique; Sonde not used (for deeper locates). | Ensure proper sweep technique. Minimize interference by moving away from other known utilities. Note that depth accuracy is improved with a Sonde (not included). |
| Hazard Zone alert constantly active. | Operating in an area with numerous shallow utilities. | Proceed with extreme caution. Re-evaluate the site for potential hazards. |
