OPERATION OF RECEIVER
Four Operating Modes in
Receiver
The .PL-2000 .Receiver .has .4 .operating .
modes: .Peak, .Null, .DIST, .and .Sonde .
1 . . .Peak .Mode
The ."Peak" .Mode .employs .the .PL-2000's .
patented .differential .antenna .to .pro-
duce .the .most .accurate .locates . .Depth .
Measurement .(+ .or .– .5% .accuracy) .is .
available .in .Peak .Mode .
2 . . .Null .Mode
The .PL-2000's ."Null" .mode .is .a .fast .locat-
ing .tool .with ."left-right" .guidance .in .a .cross-
section .view .of .the .pipe .and .the .user .
3 . . .DIST .Mode
The ."DIST" .Mode .offers .even .longer .
distance .locating .than .the .Peak .Mode, .
as .much .as .40% .– .50% .further . .Locating .
accuracy .is .less .in .the .DIST .Mode, .and .
Depth .Measurement .is .not .available .
4 . . .Sonde .Mode
The ."Sonde" .Mode .allows .the .Receiver .
to .locate .sewer .Sondes .accurately .and .
measure .their .depths .correctly . . A ny .512 .
Hertz .Sonde .or .the .SubSurface .8 .kHz .
Sonde .can .be .used .
Three Active Frequencies and
Two Passive Frequencies
The .PL-2000 .Receiver .has .3 ."active" .
frequencies, .meaning .these .frequencies .
are .transmitted .by .the .Transmitter .and .
matched .by .the .Receiver: .27kHz, .8Hz .
and .0 .5kHz . .Higher .frequencies ."bleed" .
off .faster .than .lower .frequencies, .and .
lower .frequences .will .go .longer .distances .
down .the .pipes .and .cables . .However, .
higher .frequencies .can .be .applied .more
