Declassification and Security Instructions
Introduction
If you have data security concerns, this document tells you how to clear or sanitize the Model DMM6500 or
DAQ6510 memory devices. It also explains how to declassify an instrument that is not functioning.
The procedures in this document are written to meet the requirements specified in:
• NISPOM, DoD 5220.22-M, chapter 8
• ISFO Process Manual for Certification and Accreditation of Classified Systems under NISPOM

Products
This document contains procedures for the following Keithley Instruments models:
• DMM6500
• DAQ6510
Terminology
The following terms may be used in this document:
• Clear: Removes data on media or in memory before reusing it in a secured area. Clears all reusable
memory to deny access to previously unsecured information.
• Demo setups: Demonstration modules that come loaded on the instrument; you cannot modify them.
• Direct method of modification: You can modify data directly.
• Erase: Equivalent to clear (see above).
• Indirect method of modification: The instrument system resources modify the data; you cannot modify it.
• Instrument declassification: Procedures that must be completed before an instrument can be removed
from a secure environment. Declassification procedures include memory sanitization and memory removal.
• Media storage and data export device: 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 power is turned off.
• Protected user data area: Contains data that is protected by a password.

• Remove: Clears instrument data by physically removing the memory device from the instrument.
• Sanitize: Eradicates instrument data from media and memory so it cannot be recovered by other means or
technology. This is typically used when the device will be moved (temporarily or permanently) from
ecured area to a non-secured area.
s
• Scrub: Directly retrieve and clear the contents of the memory device.
• User accessible: You can directly retrieve the contents of the memory device.
• User data: Measurement data that represents signals that you connect to the instrument.
• User-modifiable: You can write to the memory device during normal instrument operation using th
ront-panel interface or remote control.
f
• User settings: Instrument settings that you can change.
• Volatile memory: Temporary memory; data is lost when the instrument is turned off.
Description of memory
All Model DMM6500 and DAQ6510 instruments share common volatile and nonvolatile memory components.
These instructions will work for all instruments listed in the Products
All Model DMM6500 and DAQ6510 instruments contain the following volatile and nonvolatile memory:
MASTER/BLASTER/DISPLAY (U58 on 389517200/1 board): Contains instrument logic, calibration data, and
customer scripts, readings, and data.
(1) 32 MB nonvolatile NOR FLASH chips on the digital board
section above.

e
(3) 128 MB volatile DDR2 SDRAM chips on the digital board
he DMM6500 and DAQ6510 instruments contain a battery-backed clock that is used for time-stamping.
T
It does not store data.
