5.3 Täpsemad funktsioonid

Refer to the detailed software manual (if applicable) for instructions on advanced functions such as spectral scanning, kinetics, and multi-wavelength analysis. These functions typically require connection to a computer and specialized software.

6. Hooldus

6.1 Puhastamine

• Välimus: Pühkige välispindu pehme, damp riie. Ärge kasutage abrasiivseid puhastusvahendeid ega lahusteid.
• Sample Compartment: Hoidke sample compartment clean and dry. Use a lint-free cloth to remove any spills.
• Cuvettes: Always use clean cuvettes. Rinse them thoroughly with appropriate solvent and dry them before use.

6.2 lamp Asendamine

The UV and Visible lamps have a finite lifespan. When lamp performance degrades (e.g., unstable readings, low energy), they may need replacement. This procedure should ideally be performed by qualified service personnel or by following specific instructions in a service manual, as it involves sensitive optical components.

6.3 Säilitamine

When not in use for extended periods, power off the instrument, disconnect it from the power supply, and cover it with a dust cover to protect it from dust and environmental contaminants.
