Indoor lighting should not be too intense. In hot weather, please do not direct a fan at the instrument, as this may cause the brightness of the tungsten lamp filament to be unstable. 3.Before use, you should understand the instrument's structure, working principle, and the functions of each control knob. Before connecting to the power supply, please check the safety of the instrument, ensure that the power connection is secure, the power supply is normal, and the initial positions of all adjustment knobs are correct, then turn on the power switch. 4.When the instrument is not powered on, the meter pointer should be at the "O" mark. If it is not, it can be adjusted with the meter calibration screw(not included). 5.Temperature and humidity affect instrument performance, which may lead to component damage or functional degradation, shortening the service life. The laboratory should maintain constant temperature and humidity, especially in southern regions. 6.dus.t and corrosive gases can reduce the flexibility and reliability of the instrument, and cause component corrosion. It is necessary to keep it clean and dus.t-proof. 7.After using for a period of time, dus.t accumulates inside the instrument. It is recommended to have professional personnel remove dus.t, calibrate, lubricate, and test and adjust it to ensure normal operation. Regular inspections and maintenance are necessary during maintenance to maintain optimal condition. 8.Please allow the slight color difference caused by the shooting light and the 1-3 cm error due to manual measurement, and make sure you do not mind before ordering.
