Any implications resulting from partial self-calibration can be eliminated by running the full self-calibration procedure.

The Assembly Part Number should be formatted as "P/N: 19####A-0#L" Procedure 2 Device Information Flash (Calibration Metadata): The user-accessible areas of the Device Configuration Flash are exposed through a calibration Applications Programming Interface (API) in LabVIEW. To clear the calibration meta-data area, complete the following steps: 1. Use function niHSDIO_InitExtCal to create and initialize a special NI-HSDIO external calibration session. The ViSession returned is an NI-HSDIO session that can be used during the calibration session. 2. Call function niHSDIO_ChangeExtCalPassword to clear the calibration password that is required to initialize an external calibration session. 3. Call function niHSDIO_CalAdjustChannelVoltage to clear the user-defined information of the selected channel(s). 4. Finally, call the function niHSDIO_CloseExtCal with the calibration action set to `Commit', in order to store the new calibration constants and data in the onboard Flash and to close the calibration session.

Contact: 866-275-6964 support@ni.com Letter of Volatility PXIe-6544/6545/6547/6548 Terms and Definitions Cycle Power: The process of completely removing power from the device and its components and allowing for adequate discharge. This process includes a complete shutdown of the PC and/or chassis containing the device; a reboot is not sufficient for the completion of this process. Volatile Memory: Requires power to maintain the stored information. When power is removed from this memory, its contents are lost. This type of memory typically contains application specific data such as capture waveforms. Non-Volatile Memory: Power is not required to maintain the stored information. Device retains its contents when power is removed. This type of memory typically contains information necessary to boot, configure, or calibrate the product or may include device power up states. User Accessible: The component is read and/or write addressable such that a user can store arbitrary information to the component from the host using a publicly distributed NI tool, such as a Driver API, the System Configuration API, or MAX. System Accessible: The component is read and/or write addressable from the host without the need to physically alter the product. Clearing: Per NIST Special Publication 800-88 Revision 1, "clearing" is a logical technique to sanitize data in all User Accessible storage locations for protection against simple non-invasive data recovery techniques using the same interface available to the user; typically applied through the standard read and write commands to the storage device. Sanitization: Per NIST Special Publication 800-88 Revision 1, "sanitization" is a process to render access to "Target Data" on the media infeasible for a given level of effort. In this document, clearing is the degree of sanitization described. November 2016 376432B-01 Rev 001 This document is subject to change without notice.
