3. MAIN APPLICATIONS

Application
Locating energized
50/60 Hz cables
carrying current
Identifying location all
metallic utilities: pipes*,
energized and
de-energized cables
Tracing individual pipes*
or cable (de-energized
cables only)
*Tracing of non-metallic pipes and conduits is possible after inserting metal fish tape or cable

3.1 General Tracing Techniques for All Applications

Receiver Locating
1. Turn the Receiver on by pressing the power button for two seconds. Select the desired locating frequency. Hold the
Receiver vertically.
2. Adjust the sensitivity, using the "
movement. The sensitivity control should be at, or close to, maximum sensitivity.
3. Keeping the Receiver vertical and in front of your body, walk across the area to be checked, then follow in a
grid pattern.
Note that there will be no sound from the speaker until the meter reading is above full scale approximately 10%.
Note that objects perpendicular to the receiver will not be detected (white objects in drawings A and B). The
Receiver will detect objects that are parallel or under angle (gray objects in drawings A and B). After performing the
initial grid search as shown in drawing A, repeat grid search at 90 degrees as shown in drawing B.

4. If at any time the meter reading starts to increase, carefully move the locator forward and back, left to right to detect
the maximum signal. Use the bar graph to help confirm the correct position. If the bar graph exceeds the maximum
value, adjust the sensitivity to bring the reading back within the limits of the bar graph using "
If the reading is off scale (too great or too small), then pressing the "
adjust the sensitivity to bring the meter deflection to 50%.
