<10. Data Files anD Format>
The TDLS200 analyzer is capable of automatically storing many important pieces of information. We would
recommend that the data files are downloaded periodically and stored at a local drive for future reference.
Also, if there is any sign of potential trouble with the analyzer and/or the process, please download files as
soon as possible to ensure potentially helpful data is stored/saved off-line.
All the files are stored in simple ASCII text format for easy importing to MS Excel spreadsheets (or other data
manipulation software as appropriate).
The rate at which data is captured may be configured from within the TDLS200 software. There are several
files that are stored in the system:
Example of files contained within the serial number specific data export folder (or the !Data folder when
viewing through a File Transfer function on Ultra-VNC connection)
092407 .res Daily Results
Allows for review of daily
results and diagnostic data
on a measurement-by-
measurement basis
Daily Results - in the form of ASCII data files that can
be opened with Microsoft “Notepad” as simple .txt file
formats. The content can then be copied and pasted
into Microsoft Excel spread. Each day as a separate file
name in the MMDDYY format with the .res file extension
(meaning result). Each
file starts with the first up-dated measurement set of data
for that date and then sequentially contains every up-dated
measurement set of data in the same dated file until the
end of that date. A new dated file is created each day. Files
are
deleted automatically on a First-In/First-Out (FIFO) basis if
the allowable Data folder has no spare memory.
092407 .spe
Daily Spectra
Allows for review of daily
results and diagnostic data
on a measurement-by-
measurement
basis
Daily Spectra - in the form of ASCII data files that can
be opened with Microsoft “Notepad” as simple .txt file
formats. The content can then be copied and pasted
into Microsoft Excel spread. Each day as a separate file
name in the MMDDYY format with the .spe file extension
(meaning spectra).
Each file contains spectra captured automatically during
that day depending on what rate of spectra capture has
been
set-up. Typically, the analyzer will capture one spectrum
every 300 measurement up-dates (if the capture rate is set
300 up-dates). Additionally, if the analyzer goes into
“Warning” of “Fault” mode during that day, there will be
spectra captured during these times (typically configured
for 5 captures in each mode). A new dated file is created
each day. Files are deleted automatically on a First-In/First-
Out
(FIFO) basis if the allowable Data folder has no spare
memory.
-------- .cap
Capture
Individually named spectra
capturedmanually
These files are the individually named spectra that are
“Captured” by the user at any given date or time during
operation. Each file can have up to 8 numerals in its name
which are entered at the time the “Capture” is performed.
