2.4.1 Spectrometer Standard Creation

Under the Oil Calibration Settings tab is an option to create a Spectrometer standard. Future
Spectrometer reading may be compared with this standard and an alarm may be raised if the
composition of the oil changes significantly.
As with the oil detection system the spectrum analyser requires the laser light as an
illumination source therefore the analyser will not operate when the measurement cycle is in
the stopped position.
2.4.1.1 What is a Spectrometer Standard
A Spectrum Standard is the "overall shape" of the Spectra that is typical of the oil passing
though the OIW-EX Series Analyzer. Figure 7 show two spectra from oil samples, if
Sample 1 was set as the Spectrometer Standard then an alarm can be raised when
Sample 2 is encountered because its shape does not match the Spectrometer Standard.
