0561_A_Annual SMS Calibration List Mechanical.xlsx

This is an Annual SMS (Scheduled Maintenance System) Calibration List for mechanical instruments and gauges aboard the USS Mount Whitney (USS MTW). The spreadsheet details 115+ measurement instruments requiring periodic calibration, organized by system owner categories including USN CSM (Combat Systems Maintenance), USN OPS (Operations), USN EWO (Engineering Work Order), and USN WEPS (Weapons). Instruments include voltmeters, ammeters, frequency meters, pressure gauges, temperature gauges, and flow meters manufactured by vendors such as Marshall, A&M Instruments, Weksler, Ashcroft, Moeller, SIERRA, and others. Calibration ranges vary from electrical measurements (0-150 VAC, 0-500 Amps) to pressure readings (0-300 PSIG) and temperature monitoring (40-180°F).

The list indicates two primary calibration schedules: a 17-month periodicity for CSM instruments with calibration dates ranging from January 2025 to June 2027, and a 1-year periodicity for operational, EWO, and WEPS instruments with January 2025 to January 2026 due dates. Several items contain exception notes, including gauges marked "Do not Cal, Needs Removal" (rows 24-28), rejected gauges (rows 31, 107), and instruments with calibration date discrepancies discovered in January 2026. The document serves as a critical maintenance tracking tool to ensure all measuring instruments remain within acceptable accuracy tolerances for safe vessel operations.
