1、 Precautions

1UV visible spectrophotometer is a precision optical instrument that requires a good working environment for the instrument.

（1）The indoor ambient temperature is 15-35 ℃. The relative humidity is not much than 80% (no condensation).

（2）The instrument should be placed on a stable flat workbench without strong vibration sources nearby.

（3）There are no strong magnetic fields, harmful gases, or corrosive gases indoors.

（4）The power supply voltage should be 220V+10%, with a frequency of 50Hz+1Hz. Units without voltage stabilizing equipment should be equipped with a voltage stabilizer of 500VA or above

Voltage source. The power supply should have a ground wire to ensure good grounding of the instrument.

（5）The power supply used by the instrument should avoid other large or frequently started electrical equipment. For example: refrigerator, freezer, empty

Adjust the electric heating equipment to avoid interference with the instruments.

（6）The laboratory must be clean, ventilated, dust-proof, and the instruments should not be directly exposed to sunlight.

2Considering that the instrument has been debugged to * * * status before leaving the factory, please do not adjust it without authorization, and do not disassemble any of its parts,

Especially avoid damaging the optical mirror surface and do not wipe it.

2、 Daily maintenance

1After each use, check if there is any overflow solution in the sample chamber and wipe it frequently to prevent waste liquid from damaging components or light

Corrosion of the road system.

2After using the instrument, it should be covered with a dust cover. Silicone bags can be placed in the sample room and light source room to prevent moisture, but it must be turned on

取出。

3Regularly conduct performance indicator testing, and promptly contact the manufacturer or local service engineer to resolve any issues.

4When the instrument is not used for a long time, special attention should be paid to the temperature and humidity of the environment, and the silicone gel should be replaced regularly. Suggest opening every other week

The machine runs for one hour.

5Attention should be paid to preventing scratches, waterproofing, dust prevention, and corrosion during daily use and storage of LCD displays and keyboards used in instruments.

3、 Common problem handling of UV spectrophotometer

After the instrument is powered on or connected to a computer, it will undergo various initialization and testing. After each operation is completed, it will

Provide status information, display as normal after normal completion, display as error if abnormal, and prompt you whether to continue initialization

Operation. You can refer to the table below based on the information obtained from each operation to gain a preliminary understanding of the condition of the instrument.
