This screen is not available in the Power or Radio passive modes.
The sensitivity is set in the Manual Left/Right mode by pressing the “+” and “-” pushbuttons. The gain setting can be seen in the
top left of the screen. This has the advantage of enabling the operator to adjust the sensitivity to signals from a deep pipe or
cable. It can also be used to mask out the signal from an unwanted source.
To reject an unwanted signal, first set the sensitivity to a high value such that the unwanted signal is detectable. Sweep across
the unwanted signal, reducing the sensitivity until the locate bar ceases to respond to the signal. Now double-check that the
wanted line is detectable. Keep the sensitivity at this setting and continue to locate the line.
This display is not available in the Power or Radio passive modes. Use Peak Display for passive modes.
