LATERAL TRACING OPERATION
While tracing a line using the Lateral Mode, the display will appear as
illustrated below. The SIGNAL number indicates the strength of the
field emitted by the buried line. The buried line is located at the spot
where the maximum SIGNAL number
is indicated. If you move left or right
of the spot where the maximum
SIGNAL number is found, the value
displayed will fall.
Walk across the location of
the lateral line with the blade
perpendicular to the lateral line.
Programming:
While in Lateral Mode, press-and-hold to program:
• To exit Lateral programming, press-and-hold again.
• To set the upper limit of the signal range, press .
Each press of toggles through the program choices:
50, 100, 150, 200, 250 or 300
Set this upper limit just above the maximum SIGNAL strength
number that appears during your lateral trace.
The correct setting will make it easier to hear the peak in the
signal as you pass over the lateral line.
Set the number just above the highest SIGNAL number.
Examples:
If the highest lateral
SIGNAL number is:
Set to:
137
150
159
200
310
300
(300 is the maximum possible)
Changes to this upper limit of the
SIGNAL RANGE are saved to memory.
Changing this upper limit is similar
to the gain adjustment on other line
tracers which use a peak mode of
operation. Set the number just above
the highest SIGNAL number, as
described above.
