5 File Storage for Traces, Screen Images & Set-ups
The instrument incorporates a large Flash based disk drive for the storage of a variety of
different file types including Traces, Screen Images and Instrument Set-ups. When the
upgrade pack (U02) is fitted it may also include Logging Files, Limit Pattern Tables and
Amplitude Compensation Tables.
The instrument filing system provides a consistent method for storing, recalling, renaming,
deleting and copying files. Files can be transferred to and from a personal computer for
backup, analysis, printing and documentation purposes.
Whenever files are being accessed, the front panel LED marked Disk flashes. Depending upon
the file operation in progress, there may be a significant delay before further key operations are
possible.
