off during a recording, all recording data will be lost. Turning off the CD42 receiver during a
recording is much like turning your desktop computer off while it is writing data to the hard
disk drive.
When the pig passage has been recorded, simply press the “STOP REC” button to instruct the receiver
to stop watching for pig passages. After pressing the “STOP REC” button, the receiver may be moved
without concern of causing a false trigger to be recorded.
Entering the Location ID
Before pig recording is started, whether in manual or automatic mode, the operator has the
opportunity to enter a unique “Location ID” for each site. The Location ID can be the mile or
kilometer marker of the current location, or it can simply be a number from 0 to 999. If the operator
uses the mile or kilometer Location ID, he may use that information to calculate the pig‟s traveling
speed as discussed below in the section entitled “Calculate a Pig‟s Speed” beginning on page 26.
When an operator presses the RECord button to begin recording pig passages, the Location ID menu
is shown and should appear similar to the one shown in Figure 21. At this point the operator may
enter a Location ID. The operator has the option of entering the Location ID in any of the available
fields. For instance, if the operator enters a number in the MILE field, the CD42 receiver will
automatically update all other fields as well.
Figure 21 Setting the Location ID
Entering a Location ID is quickly done using the red navigation buttons. The Left and Right arrow
buttons control the movement of the cursor throughout the screen. The Up and Down arrows,
labeled (+) and (-), change the value of the selected field. Simply press the Left or Right button
until the field to be changed is highlighted, and then press the Up or Down arrow to select the
correct value.
When the correct Location ID is entered, press the
OK button to save this information and enter
record mode. To cancel the record operation and return to the Main Menu, press the Abort button at
any time.
