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.

NOTE

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 Vision software via an

external computer.

2￭￭￭￭￭￭￭￭

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. Usage of the NIRS DS2500 Analyzer therefore requires the user to

have basic knowledge and experience in handling toxic and caustic sub-

stances. Knowledge with respect to the application of the 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 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 com-

plete 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.

3.2 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 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.

3.3 Connecting the power supply cable ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭

8￭￭￭￭￭￭￭￭

NOTE

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

6.2.2 Replacing the fan filter, page 28.

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 supply cable

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 supply cable (DIN EN 60320-1), which

can be used for connecting to the power supply.

3.4 Connecting the data cable

To be controlled, the NIRS DS2500 Analyzer is connected to a computer

either directly or via a local network (LAN).

Use the supplied crossover data cable for connecting the instrument

directly to a computer's network card.

For a connection via your local network, you will need a straight-through

cable, which is not supplied with the instrument. As network configura-

tions vary considerably across different companies, a full discussion is not

possible in this manual. We recommend that you have your network spe-

cialist establish the connection between the instrument and the company

network.
