Compulsory verification refers to medical measuring instruments that must be verified by legal metrological verification institutions, generally referring to medical measuring instruments used for trade settlement and personal safety. Optional verification can be done internally (if there is a laboratory, and the laboratory has passed the metrological certification). Periodic verification means that every medical measuring instrument has a verification cycle, such as ECG machine, B-ultrasound machine, ophthalmic optometry instrument once a year, sphygmomanometer and pressure gauge once every six months. One-time verification means that some instruments apply for verification when they leave the factory or are used for the first time, and do not need to be verified again within the service life.
