■ Liquid samples: liquids or suspensions ■ The NIRS DS2500 Analyzer is a robust instrument that is resistant to mois- ture, dust, vibrations and temperature fluctuations. As a result, it can be operated in a variety of production facilities. The NIRS DS2500 Analyzer is operated with the Vision software via an external computer.
■■■■■■■■■■■■■■■■■■■■■■ 1.2 Intended use Intended use The NIRS DS2500 Analyzer is designed for use in production facilities. It can be used for incoming goods inspection or atline for production pro- cess monitoring. This instrument is suitable for measuring chemicals and flammable sam- ples.
1.4.2 Electrical safety The electrical safety when working with the instrument is ensured as part of the international standard IEC 61010. WARNING Only personnel qualified by Metrohm are authorized to carry out service work on electronic components. ■■■■■■■■...
■■■■■■■■■■■■■■■■■■■■■■ 1.4 Safety instructions WARNING Never open the housing of the instrument. The instrument could be damaged by this. There is also a risk of serious injury if live components are touched. There are no parts inside the housing which can be serviced or replaced by the user.

3.1.3 Scope of application The NIRS DS2500 Analyzer is designed for offline use in the laboratory or atline use in the production process. Setting up the instrument Like most high-precision instruments, the NIRS DS2500 Analyzer is sensi- tive to ambient conditions, which may negatively influence its perfor- mance and shorten its service life.
Vibrations and shocks interfere with the sensitive optical and mechanical components and compromise calibration and measuring accuracy. Set up the NIRS DS2500 Analyzer at a stable workplace that does not propagate vibrations resulting from manual work (e.g. typing on the com- puter keyboard).
