What is the meaning of repeatability?

Repeatability is an important basis for assessing the state of the instrument. The good repeatability of the instrument shows that the laser, detector, signal transmission system, control system, sample preparation system, and software system of this instrument are stable and normal. The operating environment of the instrument is also suitable, and the instrument is capable of normal particle size. Test works. If the repeatability is not good, it means that the instrument is faulty. It is necessary to inspect the laser, detector, signal transmission system, control system, sample preparation system and software system, as well as the operating environment of the instrument, including voltage, direct sunlight, Vibration, electromagnetic interference, etc. It is necessary to find out the reason and eliminate the factors causing poor repeatability before proceeding with follow-up work.
