About Trace Modes
Peak: In this mode, as the antenna crosses the cable, the Receiver speaker volume
increases to a maximum and the bar graph fills from both sides toward the middle.
As the antenna moves off the cable path, the speaker volume decreases and the bar
graph opens.
Peak with High-Expanded: While in Peak mode, press to select High-
Expanded (the highest setting). Speaker response is cut off as the antenna moves
away from the cable.
Null: In this mode, the signal is a minimum directly over the cable and is
maximum on either side of the cable. The speaker volume and display signal
strength correspond to the signal being received. In the normal bar graph display
mode (Null flag flashing) the bar graph opens at low signal strength and closes at
high signal strength. In the inverse Null bar graph display mode (Null flag is on
solid), the bar graph closes at low signal strength and opens at high signal strength.
Differential: In this mode, the Receiver provides an indication of the relative
position of the cable to the Receiver by displaying right or left arrows (the arrow
points toward the cable). The bar graph increases to a maximum as the Receiver
antenna is moved directly over the cable path. Speaker response is a high warbling
tone to the right of the cable path, a low warbling tone to the left, and a solid tone
directly over the cable.
Special Peak Mode: This mode will increase the signal sensitivity of the
Receiver when the signal is too weak for normal tracing. Use special attention when
using this mode because it is more susceptible to congestion than the normal peak mode.
Numerical Signal Strength Display Resolution: The user may select
between 3 levels of signal strength resolution. The setting will be displayed on the
right end of the bar graph during selection. To change the setting, press and hold
the key during power up then press the key. Display resolution may
be changed between the standard 1X, (no bars illuminated), 2X, (One bar
illuminated), and 4X (Two bars illuminated). The unit saves the last setting until
changed.
Note: While tracing cables in any mode, keep the Receiver handle in line with the
suspected cable path.
