Apply Data Security (2638A and 1586A)
This setting is not associated with the Software security
programs settings which control program access. This
setting is used for data and configuration files created
internally by the 1586A and 2638A. When checked, and
data storage is set to Internal or USB, this setting adds
instrument user ID information to the setup file
information stored in the running configuration file. This
setting does not disallow unauthorized users (Guests)
from running configuration files but identifies data created
by authorized users and Guest (unverified) users. User
data, authorized user, and user name or “Guest” is stored
in the Fluke DAQ .XML configuration file.
The 2638A and 1586A create a signature field at the end
of each scan data record to data being stored in internal
memory. This signature field contains a unique checksum
value at the time of recording.
When data is sent to the Software during a “Get Scan”
operation, or imported from USB, or transferred from an
exported chart file, the Software verifies the checksum
contained in each record. If a checksum does not match,
a warning is issued that the data has been corrupted and
checksum values do not match.
Upload / Download (2638A and 1586A)
In configuration mode, Upload sends the configuration file
to the remote instrument. Download sends the current
configuration file to the instrument. Fluke recommends
that you download the configuration file to remote
instruments prior to initiating scan.
