or decrease the number. Once the wavelength has been entered press the key adjacent to the tick icon
to save and return to the spectral points analysis menu.

Secondly, the wavelength can also be entered manually
in the spectral points analysis table by pressing the key
adjacent to the location in the table where the result is
to be stored. This opens a number entry screen where
the analysis point can also be deleted by pressing the key
adjacent to the delete icon.

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 wavelength has been entered or
the analysis point deleted press the key adjacent to the tick icon to save and return to the spectral points
analysis table. If a wavelength entered is outside the scan range the check number warning icon will be
displayed before the wavelength is automatically adjusted to within the range.

To view the points in the spectral points analysis table
press the key adjacent to the spectral points analysis
table icon. Only three points can be displayed on the
screen at one time; to view the other points in the table
press the key below the down arrow icon. To view the
first three points again press the key below the up arrow
icon. The table displays the wavelength and either the
corresponding absorbance or % transmittance, as well as
the order in which the points were selected or entered.
To change the photometric value between absorbance
and % transmittance press the key below the ABS icon
or %T icon. Pressing the key adjacent to the tick icon will
save any changes made and return to the spectral points
analysis menu.

It is possible to access spectral points analysis before a scan is performed. Points to be analysed can be
pre-selected from the blank axis, or entered manually in the spectral points analysis table. When the
scan has been performed the points for analysis will already be in the table with the corresponding
absorbance or % transmittance values.
