the start of a new pick list label, or by the blank line at the end of the
PICKLISTS section.
There are two special picklists. These picklists are defined using the labels
“LeakSource” and “RepairMethod”. If these picklists are present in the
route database file, they are used for the Leak Source and Repair Method
fields in the logged data. If they are not included in the file, default pick
lists are loaded. Note that the “LeakSource” picklist has a hard-coded size
of 3 characters and the “RepairMethod” picklist has a hard-coded size of 5
characters. The first entry in each of these picklists must be something
equivalent to “N/A”, as these are the default settings indicating that
nothing has been selected from the list.
The next section of the file is the DISPLAY section. This section defines
what database fields are displayed on the Enhanced probe while
monitoring. Since there are only three lines of 20 characters each available
on the display during monitoring, the user may select which fields are
displayed.
The first column of the display field is the label for the route entry field to
be displayed. This must match a label previously defined in the ROUTE
FIELDS section of the file. The second column is the line number (1-3) to
display this field. The third column is the column number (1-20) to start
displaying this field. The fourth column is the number of characters to
display. If the number of characters to be displayed exceeds the number of
characters available on the line, it will be wrapped to the next line. If the
number of characters to display is less than the number of characters
defined in the ROUTE FIELDS section, the first n characters of the field
are displayed. If the number of characters to display is a negative number,
then the last n characters of the field are displayed. An error is reported
when the file is transferred if any of the display fields overlap.
The route header line is composed of route entry field titles (line 1)
centered over an underline of dashes (line 2) for each field. The fields are
delimited with a single space. Each column is of width defined in the route
entry field section. These two lines are ignored when receiving a route
database file, so formatting is not critical.
The route entry format depends on the data in the Route Fields section.
Each field goes from left to right in the order they were defined in that
section. Each field is delimited by a single space. Numbers may be either
left or right justified. Each database entry is ended with <CR><LF>.
Downloaded route entries may be terminated any time after the tag by the
<CR><LF>. Before the first entry is accepted, the instrument’s route and
log memory is cleared. Partial text entries are processed as ending in trailing
spaces. Partial number entries are processed as if complete. The default
value for fields not included in the entry are:
