<![CDATA[Calibration now has an important role in determining the operational suitability of measuring instruments in various fields. Currently, equipment, especially measuring instruments for public and public facilities, has not yet been properly calibrated according to existing regulations. Calibration is carried out to ensure data validity Which produced frommeasuring instrument. Calibration acts as a process to ensure the accuracy, precision, and reliability of measuring instruments. This article investigates several literatures related to the role of calibration in improving the quality of measuring instruments based on calibration methods that can be used according to the urgency. The results of assessing the operational feasibility of equipment or measuring instruments are determined through a calibration process. Apart from that, calibration can be carried out using several methods such us the single point calibration method, multi point calibration method, and reference instrument calibration method. Reviews based on useful calibration literature in the fields of health, environment, technology, maritime and aviation. Implementing appropriate and documented calibration is important in supporting valid data on medical devices, scientific research, traceability of sensors from a new system, guaranteeing data reliability, and providing reliable services, as well as having a positive impact on various aspects of life and technological development.Keywords—Benefits of calibration; Calibration; Calibration method; Measuring instrument; Traceability.]]>
