Sequence of Operations — Startup
To use the system, you should first configure system variables — set the title, set the data
directory path, and set the serial communication port. After this operation, you can download
data from the instrument to your PC.
The procedure for configuring the system is:
1. Invoke the ANALYSIS program (type TVA and press ENTER). The main ANAL-
YSIS menu will appear.
NOTE: If the c: drive was not the installed drive, an error message may appear. Ignore
it and continue.
2. From the Main Analysis menu, select UTILITIES. A dialog box will appear.
3. Select VARIABLES. A dialog box will appear with three options: TITLE, DIREC-
TORY, and COM PORT.
TITLE is the name you want for your data. DIRECTORY is the full pathname of
your data directory. COM PORT is the PC serial communication port you are
using to transmit data from the analyzer to your PC.
4. Enter data for setting the variables and then press ESC twice. This returns you to
DOS.
You can now prepare to download data from the TVA-1000 instrument to your PC. The procedure
for downloading data is as follows:
1. Connect the cable between the PC and the RS-232 serial port of the instrument.
2. Turn on the TVA-1000 instrument and set the mode to PC/LINK.
3. Start the TVA program (type TVA and press ENTER).
4. From the main Analysis menu, select Data Files. This opens a dialog box with
three options, Download Data, Select Data, and Select Save Block.
5. Select the Download Data option. This opens a window in which you can assign a
new filename or select an existing file to which the incoming data will be
appended. (The screens and options are described in detail later in this section.)
After you have made your entries, press ENTER to start the download process.
6. As the downloading process proceeds, messages appear on your screen. When finished,
a DOWNLOAD COMPLETE . . . PRESS ANY KEY message appears.
Press a key to return to the menu. You are now ready to perform other data analysis
operations, as described later in this section.
CAUTION: Do not interrupt the download process for any reason because interruption
may corrupt your files.
NOTE: Error messages will appear on the PC screen if the transfer is not successful.
