MESSAGE DISPLAYED ON THE LCDHOW TO OPERATE THE RECEIVER
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. Adjust 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.
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 ow 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
ow 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
ve minutes.
• CHANGE BATT. Indicates time to change the batteries.
