12.Set the Frequency and mode of the receiver.

a.Press Freq [SK]

b.Select the same frequency on the receiver as the transmitter by pressing Active [SK Toggle].

c.Press Locate/OK [5] to save the setting and return to locate mode.

d.Press Mode [SK Toggle] until Dir Pk is displayed.

13.Stand away from the suspected target path and adjust the Gain [4] down until the bar graph opens completely.

14.Walk in a wide circle with your back toward the transmitter (about 10 to 15 feet (3–4.5 m) away).

−− Watch the receiver display and listen to the signal. Take note of where the receiver detects the strongest Signal Strength [10].

−− The bar graph will close when the unit detects a signal, and the arrows will reverse.

−− Adjust the Gain [4] down if the bar graph closes completely.

−− The Signal Strength [10] numbers on the display will change with the signal strength (smaller, as you walk away from the target path; larger, as you approach the target path).

−− Make a complete circle around the transmitter. Return to each point in the circle that the receiver detected.

15.Measure the depth and current of each point to identify the target path. The depth of the target path should be as expected and the relative current should compare to the relative current that is alternately flashing with the frequency value on the transmitter.

Note: The relative current reading will decrease steadily as the locator moves away from the transmitter. When using higher frequencies, this decline is more evident.

16.Adjust the gain so that the bar graph responds to the target path (open when off path, almost completely closed when directly over target).

17.Trace the cable/pipe at a slow walk while moving the receiver in a side-to-side motion, keeping the receiver perpendicular to the ground.

18.Measure the depth and current occasionally to verify target path.
