The following are some points to be noted about the maintenance of the high and low temperature tester:
The temperature and humidity of the high and low temperature tester are important factors that affect the performance of the instrument, which can cause corrosion of mechanical parts, reduce the finish of the metal mirror surface, and cause errors or performance degradation of the mechanical part of the high and low temperature test chamber; Corrosion of the aluminum film of components such as gratings, reflectors, focusing mirrors, etc. produces insufficient light energy, stray light, noise, etc., and even the instrument stops working, which affects the life of the high and low temperature test chamber. It should be regularly corrected during maintenance.
Dust and corrosive gases in the working environment can also affect the flexibility of the mechanical system, reduce the reliability of various limit switches, buttons, and photoelectric couplings. It is also one of the reasons for the corrosion of the aluminum film that must be learned.
After the low-temperature tester is used for a certain period, a certain amount of dust will accumulate inside. It is best to regularly open the high and low temperature test box cover to clean the inside of the high-low temperature test box under the guidance of a maintenance engineer, and refasten the radiator of each heating element , Clean the sealed window of the optical box, calibrate it if necessary, clean and lubricate the mechanical parts, and finally restore the original state, and then perform some necessary testing, adjustment and recording.
