7.2.1 Scan Settings
This function enables the graph y-axis, absorbance or % transmittance operating mode, start and end
wavelengths and scan interval to be set. To access this function press the key adjacent to the scan
settings icon in the operating menu.

7.2.1.1 Selecting Absorbance or % Transmittance
The operating mode is displayed on the left hand side of the menu. The default parameter is absorbance
and pressing the key adjacent to the ABS icon cycles the operating mode between absorbance and %
transmittance.
7.2.1.2 Setting Start and End Wavelengths
This function enables the start and end wavelengths of the spectrum scan to be set. The Genova Plus has
a spectrum range from 198 to 1000nm. To set the start wavelength in the scan settings menu press the
key adjacent to the wavelength on the far left of the x-axis. This opens the number entry screen.
Use the keys at the bottom of the screen to select the
digit to be changed and use the keys adjacent to the
arrow icons to increase or decrease the number. Once the
required start wavelength has been entered press the key
adjacent to the tick icon to save and return to the scan
settings menu.
To set the end wavelength in the scan settings menu press
the key adjacent to the wavelength icon on the far right
of the x-axis. This opens the number entry screen. Use the
keys at the bottom of the screen to select the digit to be
changed and use the arrow keys to increase or decrease
the number. Once the required end wavelength has been
entered press the key adjacent to the tick icon to save and
return to the scan settings menu.
If the start wavelength entered is the same as the end wavelength the end wavelength will automatically
be set to be one times the scan interval. For example, if the start wavelength is entered as 500nm but
the end wavelength is already set to 500nm and the scan interval is 2nm, the end wavelength will be
automatically adjusted to 502nm. If the end wavelength entered is the same as the start wavelength
