3.5 MULTI-WAVELENGTH MODE
Having selected the Multi-Wavelength Mode from the Main Menu options the following display
will be shown:
Mode
Takes the instrument back to the operating mode menu.
Set-up
Allows access to the multi-wavelength mode set-up menu and instrument set-up menu.
Sample
Initiates a sample measurement sequence. This measures the absorbance or transmittance at the first
user set wavelength, followed by the measurement of the absorbance or transmittance at the second
user set wavelength. Both measurements are displayed, together with the difference and ratio of the
readings at the two wavelengths.
Multi-Wavelength Set-up Menu
Measure Mode
Selects between transmittance or absorbance display of readings (at both wavelengths) and the difference
and ratio displays.
Wavelength #1
The first wavelength to be measured (displayed on the left hand side of the multi-wavelength screen).
The transmittance or absorbance reading at this wavelength is referenced as T1 or A1, respectively.
Wavelength #2
The second wavelength to be measured (displayed on the right hand side of the multi-wavelength
screen). The transmittance or absorbance reading at this wavelength is referenced as T2 or A2,
respectively.
