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.
