13.2.1.4 Setting the Dilution Factor

In the settings menu press the key below the dilution icon.
This screen allows the user to input the relative sample
and diluent volumes which have been used to prepare
the sample being measured. Using this information, the
instrument calculates a dilution factor which allows the
instrument to determine and display the concentration of
the original undiluted sample.

The volume of sample is entered by pressing the key
adjacent to the sample volume icon. This will open 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 volume has been entered press
the key adjacent to the tick icon to save the changes and
return to the settings.

The volume of diluent is entered by pressing the key
adjacent to the diluent volume icon. This will open 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 volume has been entered press
the key adjacent to the tick icon to save the changes and
return to the settings.

After the sample and diluent volumes have been entered
the dilution factor screen will show a summary of the
dilution information entered.

13.2.1.5 Setting the Reference Wavelength

The reference wavelength will be included in the concentration and ratio calculations when the reference
wavelength icon is showing a tick. When enabled, an additional 4

th

wavelength will become available

to the user to edit. The wavelength of the reference measurement can be edited in the same manner as
described in section 13.2.1.1.

In the settings menu press the key adjacent to the
concentration calculation icon. This screen allows the user
to select the required concentration calculation equation
from the following list of options:
