Summary of Memory Card Operations

Memory card operations use a small, lightweight memory card (Figure 3-1) to save and
load setup files (instrument configurations) and to record measurement data during
scanning. The memory card consists of static random-access memory (SRAM) powered
by an internal battery. Care should be taken not to drop or bend the card, and to keep it
dry and away from high and low temperature extremes. Memory card operation is
allowed in the same temperatures and humidity specifications that apply to the
instrument (see Appendix A, "Specifications"). SRAM memory cards are readily
available from supply houses serving the computer industry, or from Fluke (see Table 1-
2, "Options and Accessories").

Memory Card Files
Two types of memory card files are used. Files that store instrument configurations are
setup files, SEtxx, and files that store measurement data are data files, dAtxx, where xx
is and integer from 00 to 99. The number xx can be assigned by the instrument or
selected by the operator. When the assigned integer reaches 99, previous integers
available from erased files or numbers skipped over are reassigned for subsequent new
files. The memory card can contain a maximum of 100 SEtxx and 100 dAtxx files.
