1. Cleaning: Regularly clean the surface of the instrument and the sample chamber to avoid dust and impurities from adhering and affecting measurement accuracy.

2. Calibration: Regularly calibrate the instrument to ensure accurate and reliable measurement results. Calibration should be carried out according to the instrument manual, generally requiring the use of standard solutions and control samples.

3. Light source maintenance: The light source is one of the key components of the photometer and requires regular inspection and replacement. Old light sources can affect measurement accuracy, so it is recommended to replace them once a year or according to the instrument instructions.

4. Power maintenance: Maintaining a stable voltage can ensure the normal operation of the instrument, so attention should be paid to the connection of the power line and the stability of the voltage.

5. Storage: When not in use for a long time, the instrument should be stored in a dry, dark, and ventilated place to prevent dust and moisture from entering the instrument and affecting its performance and lifespan.

It should be noted that before operating the instrument, one should familiarize themselves with the instrument's user manual and strictly follow the instructions for maintenance and operation.
