• Select the Induction Peak (IndPk) mode, and press the Gain (+ or -) until the bar
graph is just visible.
Sweeping
•
Sweeping can be done at close distances between the transmitter and receiver.
• For best results, the receiver should be at least 7.6 m (25 feet) away from the
transmitter to begin tracing the target path and have the gain set between 78-84%
when starting the sweep. Attempting to trace the target close to the transmitter may
lead to false indications due to the receiver detecting the large magnetic field radiating
from the transmitter.
•
Induction Peak mode cancels the air signal coming directly from the transmitter
induction antenna to the receiver. Increasing the sweep distance between the
transmitter and receiver reduces the direct air signal and allows for sensing deeper
conductors and sections of metal pipes. Use Induction Peak mode when sweeping
distance between the transmitter and receiver is 7.6–20 m (25–60 feet). Beyond 20 m
(60 feet) you can also use the Special (single) Peak or Directional Peak modes.
•
Special (single) Peak can be used for maximum detection depth and range (needed
for deep conductors and metal pipes), but would require increased sweep distance
separation between the transmitter and receiver.
7. Receiver Modes
A. Directional Peak (Dir Pk)
In Dir Pk mode, four peak antennas are used to analyze the magnetic field pattern. The
bar graph indicates signal strength and the directional arrows sense the edges of the
magnetic field. The left/right arrows will indicate the direction to the nearest cable that is
in-line with the receiver handle.
As the antenna crosses the cable or pipe, the receiver speaker volume increases to a
maximum, the
Bar Graph
[1l] fills from both sides toward the middle, and the numeric
Signal Strength
[10] increases. As the antenna moves off the target path, the speaker
volume decreases and the bar graph opens. Use the bar graph and the numeric signal
strength value to locate the exact target path.
