Section 8. Working with Data Files on the PC
The Copy Condition is used almost exclusively for mixed-array
dataloggers, except when time-syncing two or more data files. See
Section 8.2.3.1.15, Time Synchronization, for additional
information.
Time Ranges
When specifying a Copy condition, a range of time values can be specified
instead of a single time. If the element being tested falls within the range, the
Copy condition is satisfied and the data is processed. A range is indicated by
entering two periods between the first and last values of the range.
Examples:
Table-based
With an entry of
1:1:1[600..1200]:1 in the Copy condition, Split will only
process the data file when the time is between 6:00 a.m. and 12:00 p.m.
(Since the timestamp for table-based dataloggers is all one string,
each portion of the timestamp (year, day, hour/minute, seconds) will
use the same element number. Colons are used to separate each
portion. The format is 1[year]:1[day]:1[hhmm]:1[seconds] (the
number 1 was used since, typically, the timestamp is the first element
in the data string). In this format, hhmm is the four-digit
hour/minute.)
Array-based
With an entry of
1[30] and 2:3:4[600..1200]: in the Copy condition, Split
will only process the data file when the time is between 6:00 a.m. and
12:00 p.m.
(This assumes 2 is the year element, 3 is the day element, and 4 is the
hour/minute element.)
Time ranges cannot be used with the time-sync function.
8.2.3.1.6 Select
The Select line specifies which elements of an Output Array are selected for
processing and/or output to the specified Output File. The Select line becomes
operable only after the Start Condition and Copy condition are met, and before
the Stop Condition is satisfied. If the Select line is left blank, all elements in
output arrays meeting the Start Condition and Copy conditions are output to the
Output File.
Processing is accomplished through arithmetic operators, math functions,
spatial functions, and time series functions.
