Terms
The following terms may be used in this document:
Clear.
This removes data on media/memory before reusing it in a secured
area. All reusable memory is cleared to deny access to previously stored
information by standard means of access.
Erase.
This is equivalent to clear.
Media storage/data export device.
Any of several devices that can be used
to store or export data from the instrument, such as a USB port.
Nonvolatile memory.
Data is retained when the instrument is powered off.
Remove.
This is a physical means to clear the data by removing the memory
device from the instrument. Instructions are available in the product Service
Manual.
Sanitize.
This eradicates the data from media/memory so that the data cannot
be recovered by other means or technology. This is typically used when the
device will be moved (temporarily or permanently) from a secured area to a
non-secured area.
Scrub.
This is equivalent to sanitize.
User-modifiable.
The user can write to the memory device during normal
instrument operation, using the instrument interface or remote control.
Volatile memory.
Data is lost when the instrument is powered off.
