series of self checks and then the START-UP screen
will be displayed, as shown in figure 5.1 (right).
The information displayed here is:
•
Time and Date Set

Current Internal Temperature
•
Battery %
•
Antenna Status (

Function Keys:
- Search Key
- Pipeline Specification
Menu - Menu Key
- GPS ON/OFF
Note:
The pipe symbol (
) will only display if no pipeline details have been entered.
Calculated conductance, resistance and cover data cannot be displayed unless the
pipeline diameter and wall thickness are entered.
Pressing the Search Key to enter the search screen will automatically turn on the
GPS to ensure that GPS data is recorded during surveying. Pressing the
GPS
ON/OFF
key will manually activate the GPS system and after a few seconds the
screen will change to GPS ON to indicate that GPS is now searching.
5.2. Pipeline Specification Screen
In order for C-SCAN to calculate the conductance, resistance and depth of cover, the
pipeline diameter needs to be entered. This can be done from the START-UP screen or
during a survey. From the START-UP screen press the
PIPE
symbol (
) (if the symbol
is not displayed then details have been previously entered during a survey). The
PIPELINE SPECIFICATION screen is now displayed, see figure 5.2.
Using the keys
OD UP
or
OD DOWN
, scroll the list until
the appropriate OD (outside diameter) is selected.
Similarly, using the
WALL UP
or
WALL DOWN
keys,
select the wall thickness required.
When your selection is complete press to confirm.
Pressing
