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.
