What Is The Importance Of Repeatability?
Repeatability is important evidence used to evaluate the current status of the instrument. Good repeatability indicates that all parts of the instrument, including laser, detector, signal transmission system, control system, sampling system, and software, are stable and normal. And the operation environment of the instrument is suitable. The instrument can be used successfully to measure particle size under current operation conditions. If the repeatability is not good, it suggests problem (or problems) of the instrument, operation, or environment. In this case, the parts of the instrument, including laser, detector, signal transmission system, control system, sampling system, and software, and the operation environment, including voltage, direct exposure to sunlight, vibration, and electromagnetic interference, should be examined carefully. The instrument can only be used again until the causes for poor repeatability are found and corrected.
