1 Introduction
This manual gives you a comprehensive overview of the installation and
maintenance of the NIRS DS2500 Analyzer. The NIRS DS2500 Analyzer is
operated with the Vision software. You can find information on operating
the instrument in the tutorial and in the software manual.

1.1 Instrument description
1 Introduction
The NIRS DS2500 Analyzer is a compact measuring instrument for reflection measurement in the near-infrared wavelength range. The polychromatic light is dispersed by the monochromator built into the NIRS DS2500
Analyzer into monochromatic wavelengths before striking the sample. This
reduces sample heating. The instrument operates in the range from 400
to 2,500 nm.
The NIRS DS2500 Analyzer is designed for quality monitoring in production processes and can be applied for the following purposes:
￭ Quick and non-destructive incoming goods inspection of raw materials
￭ Production process monitoring
￭ Final inspection of finished products
The NIRS DS2500 Analyzer can be used to measure the following sample
types:
￭ Solid samples: powders or granulated substances
￭ Liquid samples: liquids or suspensions
The NIRS DS2500 Analyzer is a robust instrument that is resistant to moisture, 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.

3 Installation
3.1 Unpacking and inspecting the instrument
3.1.1 Packaging
The instrument is supplied in highly protective special packaging together
with the separately packed accessories. Keep this packaging, as only this
ensures safe transportation of the instrument.
3.1.2 Checks
Immediately after receipt, check whether the shipment has arrived complete and without damage by comparing it with the delivery note.
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.
3 Installation
3.2 Setting up the instrument
Like most high-precision instruments, the NIRS DS2500 Analyzer is sensitive to ambient conditions, which may negatively influence its performance and shorten its service life. The following guidelines have to be
observed when the instrument is set up and put into operation:
3.2.1 Ambient conditions
The ambient conditions are decisive for a proper functioning and to
ensure accurate measured values. These conditions are listed in the technical specifications (see Chapter 8.3, page 33).
High humidity and unexpectedly large fluctuations in the room climate do
not hamper the instrument's performance, but they may compromise the
measuring accuracy.
