Setup Files

When the front panel controls have been used to configure channels for a particular
instrument application, including type of measurement, alarms, scaling, rate, and all
other operating parameters, this configuration can be saved as a SEtxx files. If this is the
first setup file saved on the memory card, the instrument will assign 00 for the file name
SEt00, or you can select your own file number. The instrument displays only the SEtxx
portion, but all files are appended with the extension .HYD. Subsequent setup files
would be Set01, Set02, and so on. The user should note the file name assigned or
selected for a particular instrument configuration. A directory of card files are easily
viewed and print out using the directory feature (Figure 3-10). Setup files allow the
entire instrument to b e configured for an operation in and instant. The "Logger"
applications software can be used to create setup files that are tagged with a user-defined
string.

Data Files

Data files, dAtxx, are opened automatically at scanning when the memory card is
selected as a destination for measurement data. The display will indicate the file being
opened. For example, pressing the Q key will display dAt00 (for the first data file on
the memory card), which is acknowledged by pressing E, and then the scanning
begins. A file number can be selected as well. The instrument displays only the dAtxx
portion, but all files are appended with the extension .HYD. If scanning is stopped, then
resumed without changing instrument configuration or the memory cared, the data will
be appended to the opened file. If any parameter is changed or the memory card is
changed, the next scan cycle will open a new dAtxx file. Extraction measurement data
from the data files is accomplished by a PC running Starter or Logger applications
software. The data is read to the PC from the memory card in the instrument, using an
RS-232 link, or the memory card can be taken to a PC equipped with a memory card
reader (optional - see Table 1-2, "Options and Accessories"). The PC Logger
applications software allows separate data files to be edited and combined into a single
file.

Memory Card Capacity

An empty 256K-byte memory card (supplied) will store 4,800 scans of ten channels; an
empty 1M-byte memory card (optional) will store 19,800 scans of ten channels. SRAM
memory cards are available in a variety of sizes. When scanning and recording data onto
the memory card, the front panel indicates what percentage of the memory card has been
used (Figure 3-2). For example, a display of 74Pct indicates 74% of the card has been
used.
