The instrument is divided into inevitability fault fault and chance failure. Necessity is all sorts of components, components failure by long-term use, performance and structure in aging, lead to the instrument can't normal work; Contingency fault refers to all components, such as structure by outside the condition the influence, dramatic quality, and make the instrument can't normal work.

(2) is caused by a defect quality equipment fault
This kind of fault is refers to the instrument components quality is bad, the design is not reasonable, the assembly process because of negligence on the fault.

(3) after long-term use of the fault
This kind of fault and components related service life, because various components caused by aging, so is inevitable failure, such as photoelectric device, the display of aging, mechanical transmission system gradually wear, and so on.


(4) caused by the fault of the external cause
This kind of fault is by the use of the instrument and equipment conditions do not conform to the requirements of the cause, often is the main cause of fault caused by the instrument. General refers to the voltage, temperature, electric field, magnetic field and the vibration, etc.
