SECTION 10 – Multi-wavelength
The multi-wavelength measurement mode allows the user to measure a sample’s photometric absorbance
or %transmittance at two, three or four wavelengths. The mode allows the user to select from a number
of pre-set equations to add, subtract, multiply or divide the photometric readings. Following sample
measurement, the photometric readings and the selected equation’s result are displayed on the operating
menu screen.
10.1 MODE SPECIFIC PARAMETERS
The multi-wavelength operating menu enables
measurement parameters to be changed. The utility
toolbar on the left hand side of the screen enables access
to printing, print setup options, results, methods and
autologging options. For more details on the different
functions of the utility toolbar refer to section 17.
The Abs/%T icon enables the display to be set to show the absorbance or % transmittance. To change
the display press the key adjacent to the Abs/%T icon. Repeat presses will cycle the display between
absorbance and % transmittance.
The settings icon enables the wavelengths, number of wavelengths, units, resolution, concentration
calculation equation and concentration equation factors to be set.
