The instrument should be placed in a dry room. When used, it should be placed on a firm and stable workbench. The indoor lighting should not be too strong. In the hot weather, you can not use the fan to blow directly to the instrument to prevent the bulb filament from becoming bright and unstable. 2. Before using the instrument, the user should first understand the structure and working principle of the instrument, as well as the functions of each control knob. Before the power is turned on, the safety performance of the instrument should be checked. The power supply wiring should be firm and the power supply should be good. The starting position of each adjustment knob should be correct, and then press the power switch. 3. When the instrument has not been powered on, the meter pointer must be on the “O” engraving line. If this is not the case, you can adjust it with the calibration screw on the meter. Instrument maintenance: 1. Temperature and humidity are important factors affecting the performance of the instrument. They can cause corrosion of mechanical parts, reduce the smoothness of the metal mirror surface, cause errors or performance degradation of the mechanical parts of the instrument; cause optical components such as gratings, mirrors, focusing mirrors, etc. The aluminum film is rusted, resulting in insufficient light energy. Stray light, noise, etc., even the instrument stops working, thus affecting the life of the instrument. It should be regularly corrected during maintenance. It should have an instrument room with four seasons and constant humidity, and be equipped with constant temperature equipment, especially ground. Laboratory in the southern region 2, dust and corrosive gases in the environment can also affect the flexibility of the mechanical system, reduce the reliability of various limit switches, buttons, photoelectric couplers, and also cause one of the reasons why the aluminum film corrosion of the components must be learned. Clean, protect the environment and the indoor sanitary conditions of the instrument, dustproof 3. After the instrument has been used for a certain period of time, a certain amount of dust will accumulate inside. It is best to start the dust removal work by the maintenance engineer or the engineer under the guidance of the engineer, and re-tighten the radiator of each heating element. The sealed window of the box is cleaned. If necessary, calibrate the optical path, clean the mechanical parts and necessary lubrication, and finally, restore the original condition, and then perform some necessary tests, adjustments and records. Note: Please allow 2-3cm error for manual measurement
