Emerson Automation Solutions 6021 Innovation Blvd Shakopee, MN 55379 USA Attention: Application Examiner Re: Request for confidentiality Applicant: Rosemount, Inc. FCC ID: LW2-248DX58 To whom it may concern, Permanent Confidentiality Request is hereby submitted by Rosemount, Inc. to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: • Schematics • Detailed Block diagrams • Detailed Operational/Functional Description This device is a non-consumer device inaccessible to general public and is only accessable by qualified technical personnel in the industrial control industry. Short-term Confidentiality Request is hereby submitted by Rosemount Inc. to withhold from public review for a period of 45 days from the date of the Grant of Equipment Authorization and prior to marketing, certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept confidential for a period of 45 days from the date of Authorization: • Test setup photos • External photos • Internal photos • User manual Rationale for request for confidentiality: Rosemount Inc. has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us. Disclosure of the short-term confidential portions of this application during the period of importation and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development. Sincerely, Elizabeth Reierson Approvals Engineer Rosemount Inc.

The difference is the result of tolerances in the measurement system that cannot be completely eliminated. To the extent that technology allows us, it has been our aim to minimize this error. Measurement uncertainty is a statistical expression of measurement error qualified by a probability distribution. A measurement uncertainty estimation has been performed for each test per our internal quality document QM205.4.6. The estimation is used to compare the measured result with its "true" or theoretically correct value. The expanded measurement uncertainty (K=2) can be found included as part of the applicable test description page. Our measurement data meets or exceeds the measurement uncertainty requirements of the applicable specification; therefore, the test data can be compared directly to the specification limit to determine compliance. The calculations for estimating measurement uncertainty are based upon ETSI TR 100 028 (or CISPR 16-4-2 as applicable), and are available upon request. The following table rep…
