The settings menu is accessed through the expanded
operating menu by pressing the key adjacent to the
settings
icon. In the settings menu press the key below
the
wavelength
icon.
This will open a number entry screen. Use the keys at the
bottom of the screen to select the digit to be adjusted.
Use the keys adjacent to the
arrow
icons to increase or
decrease the wavelength to the required number. Press
the key adjacent to the
tick
icon to save the changes and
return to the settings menu.
6.2.2 Settings
The settings menu enables the
wavelength, units, resolution, standard
or
factor
to be set and is
accessed from the expanded operating menu by pressing the key adjacent to the
settings
icon. Once
all of the required settings have been entered press the key adjacent to the
tick
icon to save and return
to the expanded operating menu.
Fig 6.2.2.1 – Settings Menu
When setting the method parameters either the standard or the factor should be selected. The standard
should be used if the factor is not known as selecting this option will calculate the factor. If the factor is
known it is not necessary to measure a known standard’s concentration. When the standard or factor is
not selected the value should be set to 1.00.
6.2.2.1 Selecting Concentration Units
The units of concentration can be selected from a number of options: no units, %, ppm, EBC, SRM,
mEq/l, mEq, M, mM, µM, nM, U, U/l, U/ml, g/l, mg/l, µg/l, ng/l, g/dl, mg/dl, µg/dl, mg/ml, µg/ml, ng/ml,
µg/µl, ng/µl, mol/l, mmol/l.
In the settings menu press the key below the
units
icon.
This opens the unit selection screen which displays all
the different units. Use the keys adjacent to the
arrow
icons to navigate around the screen to select the required
units. Once the required units have been highlighted
press the key adjacent to the
tick
icon to save and return
to the settings menu. The selected unit will be displayed
in the minimal and expanded operating menu along with
absorbance and selected wavelength.
