10. Locating in Directional Peak Mode

The following are instructions for locating a buried pipe or cable using the direct connect method and the Directional Peak (Dir Pk) mode. Other methods of connection and tracing modes/features are explained in previous sections.

Step 1. Insert the ground rod into the ground, perpendicular to the suspected target path.

Step 2. Remove the grounding from the near-end of the target cable/pipe.

Note: Never connect or disconnect the transmitter when the unit is on.

Step 3. Connect the red lead of the transmitter to the shield, neutral, or deenergized target conductor.

Step 4. Connect the black lead of the transmitter to the ground rod. Step 5. Perform a battery check by pressing and holding off [T-1].

Step 6. Power on the transmitter by pressing on [T-2] once. This will place the transmitter in Ohm-meter mode. An Indicator Flag will be displayed above the ohm symbol, , in the Digital Display [T-4].

a.A solid tone from the transmitter indicates a complete circuit with a good ground.

b.A beeping tone from the transmitter indicates a usable ground. An attempt should be made to improve the ground.

c.No tone from the transmitter indicates a poor, or no ground. The transmitter will display ‘OL’ in this instance. An attempt should be made to improve the ground. Verify that the far end is grounded.

Step 7. Press on Trace (Frequency on 2550 locator) [T-3] to set the transmitter to Trace mode.

Step 8. Select a frequency on the transmitter by pressing Trace (Frequency on 2550 locator) [T-3]. The unit will cycle through the available frequencies (577, 1K, 8K, 33K, 82K, 200K and ALL).

Step 9. Press On/Off [1] to power on the receiver.

Step 10. Press Menu/OK [5] (you may have to press Menu/OK [5] twice to toggle to the LOCATE MENU display).

Step 11. Press Cable/Pipe [SK].
