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:  2450, 2450-NFP, 2450-NFP-RACK, and 2450-RACK  2460, 2460-NFP, 2460-NFP-RACK, and 2460-RACK  2461, 2461-NFP, 2461-NFP-RACK, and 2461-RACK  2461-SYS  2470 and 2470-RACK  DMM7510, DMM7510-NFP, DMM7510-NFP-RACK, and DMM7510-RACK Contact information If you have any questions after you review the information in this documentation, please contact your local Keithley Instruments office, sales partner, or distributor. You can also call the corporate headquarters of Keithley Instruments (toll-free inside the U.S. and Canada only) at 1-800-935-5595, or from outside the U.S. at +1-440-248-0400.

Clears all reusable memory to deny access to previously unsecured information.  Demo setups: Demonstration applications 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 a secured area to a nonsecured area.  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 the front-panel interface or remote control.  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 of these instruments share common volatile and nonvolatile memory components. This document and these instructions work for all instruments listed in the Products (on page 1) section. All of these instruments contain three sets of volatile and nonvolatile memory as described below. The MASTER (U13 on the 2450-140 board) contains instrument logic, calibration data, and customer scripts, readings, and data:  Two 16 MB nonvolatile NOR FLASH chips on the Digital board  Two 128 MB volatile DDR2 SDRAM chips on the Digital board touch, test, invent Series Instruments Declassification and Security Instructions 077086201 / July 2019 3 The BLASTER (U1 on the 2450-140 board) contains instrument logic, calibration data, and customer scripts, readings, and data:  Two 16 MB nonvolatile NOR FLASH chips on the Digital board  One 128 MB volatile DDR2 SDRAM chip on the Digital board The DISPLAY (U1 on 2450-110 board) contains instrument logic and customer setups and data:  Two 16 MB nonvolatile NOR FLASH chips on the Digital board  One 128 MB Volatile DDR2 SDRAM chip on the Digital board Each instrument contains a battery-backed up clock that is used to generate timestamps. It does not store data. Older Model 2450s (Digital/Display board revision C) have two volatile DDR2 SDRAM chips for the BLASTER and DISPLAY. However, the process for clearing and sanitizing data is identical. Memory devices The following tables list the volatile and nonvolatile memory devices in the standard instrument and listed options. touch, test, invent Series Instruments Declassification and Security Instructions 4 077086201 / July 2019 Volatile memory devices The following table lists the volatile memory devices in the TTI products and memory-related information.
