b Application calibration
1. Select data record.
2. Set 3 different calibration points in the medium and specify the corresponding set
points.
A linear extrapolation is performed outside the calibrated operational range (gray
line).
The calibration curve must be monotonically increasing.
Zero calibration
The zero calibration is the reference calibration on which the calculations are based. The
spectrometer leaves the factory with a zero calibration performed in ultrapure water.
Zero calibration is performed as a recording of an ultrapure water spectrum. Proceed as
follows for this:
1. Clean the spectrometer →  32.
2. Record a reference spectrum in ultrapure water.

8.2 Cyclic cleaning
Compressed air is most suitable for automatic cyclic cleaning. The connection for
compressed air is provided on the spectrometer behind the measurement gap. The air
