CD42 Pipeline Pig Location & Tracking System
Page 7
Remove the supplied connecting cable from the case and attach the proper end to the CD42-R receiver
unit.
The connectors on each end of the cable are “keyed” to the receiver and antenna connectors to
insure that they will mate only in their proper orientation.
Next, remove the CD42-GP antenna from the carrying case. The GP antenna provides very good
sensitivity with a high rejection of the earth‟s magnetic field (why this is important is covered in detail
in “Chapter 5 - The Antenna”).
Complete the basic assembly by connecting the loose end of the connecting cable to the GP antenna‟s
female connector. Again, notice that the connector is “keyed” for proper orientation.
The Receiver
Now that the system‟s basic assembly has been completed, turn the receiver unit on by pressing the
“top” two buttons simultaneously. The “top” two buttons of the receiver are the ones nearest the
cable connector, and are indicated by two thick black lines between the LCD display and the buttons
themselves.
Instructions for turning the unit on and off are also printed on the rear panel of the
receiver.
Notice that each of the six buttons is associated with a small picture or
“icon”
on the LCD that
indicates the function of the adjacent button.
At this point, pressing any single button on the receiver will bypass the welcome screen and display
the main working screen of the receiver. The main screen is shown in Figure 2
Figure 2
The Main Screen of the Receiver
The main screen shown above is where all actual pig tracking and locating is performed when using
the CD42 receiver, and for the most basic tracking and locating jobs is the only screen needed
.
Simply put, it is not necessary to have any further knowledge of the menu items to perform useful
tracking and locating operations.
Notice the text near the center of the LCD that reads “
Gain: x
” (
x
represents a number from 1 to
9). This indicates the current sensitivity level of the receiver to transmitter signals. There are two
buttons in the upper right-hand corner of the receiver that allow quick adjustment of the sensitivity
of the receiver. The icons of these two buttons are up and down arrows and are labeled “
GAIN
”.
