NaviTrack

Tracing line (Lower Antenna Signal) – shows the

apparent direction of the field as detected at the lower

antenna.

Display Elements: Passive Trace Mode

The screen elements in Passive Trace Mode are the

same as those seen in Active Line Trace mode.

NOTE! Mode is determined by the type of target source

(Sonde or Line). For example, selecting the

512 Hz frequency from the Sonde mode section

of the frequency menu puts the SR-20 into

Sonde mode. (A frequency must be selected

from the correct category if it appears in more

than one category, such as 33 kHz).

Default Frequencies

The Master Frequency Menu contains a large set of fre-

quencies, but only some of these are made currently

available. They are made “Currently Available” by check-

ing them in the Master Frequency Menu,

as described on

page 23

. The frequencies which are currently available ap-

pear on the Main Menu when the Menu Key is pressed.

“Currently Available” frequencies can be checked in the

Main Menu, in which case they will appear when using the

Frequency Key. If they are unchecked in the Main Menu,

they will not appear when using the Frequency Key to

cycle through frequencies. Frequencies which appear in

the Main Menu and are checked for activation are called

“Checked-Active”.

Frequencies that are “Checked-Active” can be cycled

through simply by pressing the Frequency Key

(See Fi-

gure 9)

. A frequency chosen by pressing the Frequency

Key becomes the “In Use” frequency.

Currently available frequencies in default setting include:

Sonde Mode

• 512 Hz

Active Line Trace Mode

• 128 Hz

• 33 kHz

• 1 kHz

• 8 kHz

• 262 kHz

Passive Line Trace Mode

• 60 Hz (Power)

The use of these features is described in the Sonde

Locating, Active Line Tracing, and Passive Line Tracing

sections.
