The purpose of calibration is to ensure that a measuring device is accurate, reliable and consistent. Any kind of measurement is used in a decision-making process, so it is essential that the data collected is accurate. Otherwise, conclusions are drawn based on errors, and, in those cases, decisions are sometimes wrong and have negative consequences. With a well-calibrated device, the margin of error is known and taken into consideration.Continue Reading
A device that has been calibrated is able to measure in the scale most appropriate for the job, so the information is reliable. Some properties, such as viscosity, flammability, and thermal conductivity, are especially difficult to measure. The use of the proper units in calibration assures that the instrument is measuring what is intended.
Calibration is essential for guaranteeing that measurements are consistent in several ways. When making decisions, it is important to know that information is dependable even when it is collected over a period of time or by different operators. Also, location should not impact measurement readings, so calibrations are needed to ensure consistency among different geographic areas.
Once an instrument is calibrated, it must be cared for in order to retain that calibration. For example, it should not be exposed to environmental conditions for which it was not designed. Also, the device should be monitored to make certain the calibration remains steady.Learn more about Measurements
A calibration curve is a mathematical tool used in analytical chemistry that provides a set of reference points that unknown chemical substances can be compared to. When analyzing certain substances, scientists are often unable to get a completely accurate understanding of the substance's makeup. With a calibration curve, chemists can compare known information about unknown substances to make estimates about its makeup and chemical propertiesFull Answer >
Manual calibration instructions for a glucose meter include finding the coding number on the test strip vial, inserting the test strip into the meter and entering the correct coding number. For meters with automatic calibration, inserting the test disc into the meter automatically calibrates it, says Diabetic Care Blog.Full Answer >
