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.
