How to Operate the Receiver
1 . . .Push .the .Power .ON/OFF .Switch .(1)
2 . . Choose .one .of .the .following .modes .at .
the .Operating .Mode .Switch .(2):
Peak .Mode: . . Used .to .locate .the .pipeline .
with .greatest .accuracy .
Null .Mode: . . Faster .method .for .approxi-
mate .pipeline .location .
Dist .Mode: . . Used .to .locate .the .pipeline .
over .a .long .distance .
Sonde .Mode: . . Used .to .locate .non-metallic .
pipelines .such .as .PVC .pipes .
and .asbestos/cement .pipes .
with .no .tracer .wire . .
3 . . .Choose .a .frequency .(3) . .Switch .the .Re-
ceiver .frequency .to .the .same .frequency .
as .the .Transmitter . .The .sensitivity .level .
in .the .Receiver .will .be .automatically .set .
based .upon .the .strength .of .the .signal .
from .the .transmitter . . A djust .the .sensitivity .
up .or .down .until .the .signal .is .shown .on .
the .sides .of .the .pyramid .in .the .display .
4 . . .Adjust .the .sensitivity .(4) . .If .the .words .
"Excess .Sens" .appear .at .the .top .of .the .
pyramid, .reduce .the .sensitivity .(gain) .
using .the .down .arrow .key .until .the .signal .
re-appears .on .both .sides .of .the .pyramid . .
As .long .as .the .words ."Excess .Sens" .ap-
pear, .the .user .cannot .locate .the .pipeline .
position .accurately .
If .there .are .no .bold .bars .on .the .sides .of .
the .pyramid, .then .increase .the .sensitivity .
using .the .up .arrow .key .
If .the .bold .bars .are .partially .up .the .
pyramid, .then .the .user .is .locating .the .line .
accurately .

MESSAGE DISPLAYED ON THE LCD
The .PL-2000 .Transmitter .and .Receiver .display .the .
following .messages .on .the .LCD .
1. TRANSMITTER DISPLAYS
• CHANGE .BATT . . Indicates .time .to .change .the .batteries .
• OVER CURRENT Indicates very low resistance to current flow in
the .pipeline .in .the .Direct .Mode . .The .Transmitter .au-
tomatically .adjusts .the .output .power .to .reduce .current .
• IND . . Inductive .Mode
• DIR . . Direct .Mode
• . . Indicates .the .use .of .car .battery .power .
• POOR Indicates .poor .ground .conductivity .or .poor .current .
flow because of a bad connection in the Direct Mode.
• . Indicates .good .ground .conductivity .and .good .connec-
tions .in .the .Direct .Mode .
• CONTINUOUS Indicates .the .cancellation .of .the ."Automatic .OFF" .
function . .The .Transmitter .will .operate .continuously .
until .turned .OFF .or .the .batteries .are .dead .
• POWER .OFF Indicates ."Power .OFF" .after .non-operation .of .any .con-
trols .for .one .hour .or .the .Power .Switch .is .turned .OFF . .
2. RECEIVER DISPLAYS
• EXCESS .SENS Indicates .excess .sensitivity . .Depress .the .down .arrow .
key .until .the .message .disappears .
• ERROR .DEPTH Indicates .the .pipeline .depth .could .not .be .measured . .
Hold .the .Receiver .still .and .directly .over .the .line .
• ILLEGAL .FUNCTION .Indicates .the .depth .measurement .is .not .available .in
this .operating .mode .(Null .and .DIST) .
• NO .SIGNAL Indicates .the .signal .from .the .Transmitter .is .too .weak . .
• .GAIN .ERROR . Indicates .that .the .input .signal .to .the .Receiver .is .un-
stable, .and .the .depth .cannot .be .calculated . .Increase .
the .sensitivity .at .the .Receiver .or .the .output .power .at .
the .Transmitter .
• WAIT "Processing...please .wait"
• POWER .OFF Indicates .the .Power .ON/OFF .Switch .is .turned .off .
automatically .after .non-operation .of .any .controls .for .
five minutes.
• CHANGE .BATT . . Indicates .time .to .change .the .batteries .
