General information

With the Spectrum function, the absorbance or Transmission in dependency
of the wavelength is measured and recorded. The wavelength range can be
freely selected within the measuring range of the photometer. The increment
is 1 nm.
A spectrum is recorded without using any methods or profiles. All settings are
configured during measurement.
A baseline has to be recorded before a spectrum is recorded. The baseline
has to cover at least the wavelength range of the spectrum to be recorded.
Once the baseline is measured, it remains stored in the photometer until
 a new baseline is recorded
 the Spectrum mode is exited or the photometer is switched off
You can record a spectrum with standard settings without opening the setting
window.
The following settings are possible for a spectrum:
Input field
Wavelength start
Wavelength stop
Mode
Smoothing
Scaling
Scaling: Auto*
Scaling:Manual
Y-axis min
Y-axis max
* default setting
Note
You can store the current settings as a profile with [Save].
You can load a stored profile with [Open].
Profiles for spectra have the file extension, ".profil".
Possible entries
320* ... 1100 nm
320 ... 1100* nm
Absorbance* or Transmission
Yes* or No
Auto* or Manual
During measurement, the instrument adjusts the
axis scaling (minimum and maximum value of the
axis) to the measured values. The entire curve is
always visible.
The axis scaling (minimum and maximum value of
the axis) is set manually.
