Point calibration is a process used to ensure that a measurement device, such as a sensor or instrument, provides accurate readings. This involves comparing the device's output to a known standard or reference point. By adjusting the device based on these comparisons, users can improve the precision of their measurements. In various fields, including science, engineering, and medicine, point calibration is essential for maintaining the reliability of data. For example, in laboratories, calibrating equipment like thermometers or scales helps ensure that experiments yield valid results, ultimately supporting better decision-making and outcomes.
