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 control software. You can find information on operat-
ing the instrument in the tutorial and in the manual for the control soft-
ware.
NOTICE
You can request application descriptions in the form of
Application Notes and Application Bulletins from your
Metrohm representative or download them from
http://www.metrohm.com.
1.1 Instrument description
The NIRS DS2500 Analyzer is a compact measuring instrument for reflec-
tion measurement in the near-infrared wavelength range. The polychro-
matic 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 produc-
tion 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 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 control software via an
external computer.

1.2 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. Therefore, the use of the NIRS DS2500 Analyzer requires the user to
have basic knowledge and experience in handling toxic and caustic sub-
stances. Knowledge regarding the application of fire prevention measures
prescribed for laboratories is also mandatory.

3 Installation
3.1 Unpacking and inspecting the instrument
3.1.1 Packaging
The instrument is supplied in protective packaging together with the sepa-
rately 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 com-
plete and without damage by comparing it with the delivery note.
3.1.3 Application area
The NIRS DS2500 Analyzer is designed for offline use in the laboratory or
atline use in the production process.
3.2 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. 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 techni-
cal specifications (see chapter 6.3, page 35).
High humidity and unexpectedly large fluctuations in the room climate do
not hamper the instrument's performance, but they may compromise the
measuring accuracy.

3.3 Connecting the power cord ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
8￭￭￭￭￭￭￭￭
NOTICE
Problems during calibration/measurement
If the expected results are not obtained during calibration, the test runs
and measurements, then you should check the ambient conditions.
Strong draft (air conditioning, open windows, etc.) and exposure to
direct sunlight should be prevented.
Make sure to allow enough free space (on the sides and the back at
least 100 mm) around the instrument to prevent heat accumulation.
3.2.2 General conditions
Dust and dirt may compromise the instrument's cooling and should there-
fore be prevented as far as possible.
The maintenance procedures for the fan filter are described in Chapter
5.2.2 Replacing the fan filter, page 30.
3.2.3 Vibrations and shocks
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). Do not set up other instruments that cause vibrations
and shocks (mills, mixers, stirrers, etc.) on the same workplace.
3.3 Connecting the power cord
The NIRS DS2500 Analyzer's power supply unit is supplied as part of the
NIRS DS2500 Accessory Kit (6.7400.030). The power supply unit is fitted
with a socket for a standard power cord (DIN EN 60320-1), which can be
used for connecting to the power grid.

3.4 Connecting the data cable
In order to control the NIRS DS2500 Analyzer, it is connected to a com-
puter either directly or via a local network (LAN).
Use the supplied data cable for connecting the instrument directly to a
computer's network card.
Additional steps might be required for connecting via your local network.
As network configurations vary considerably across different companies, a
full discussion is not possible in this manual. We recommend that you
have your network specialist establish the connection between the instru-
ment and the company network.
