Auxiliary Officer and Electrical Division Section 1 Common Core Practice Test

Calibration is handled in three levels to keep equipment usable in the field while maintaining accuracy and traceability. The shipboard field calibration activity is the on-site, quick check and adjustment done on the ship with portable reference tools so gear stays within tolerance during operations. When more thorough verification is needed, the item goes to a shore-based facility called SISCAL, which uses higher-precision standards and better environmental controls to bring the equipment closer to specification. If issues remain or the highest level of accuracy and repair are required, the unit is sent to the depot-level Calibration and Repair Center (RCC) for full calibration, repair, and traceability to national standards. This combination—shipboard (FCA), SISCAL, and depot RCC—covers the full calibration pathway, from on-site checks to the most rigorous lab-level work.
