3.5 Reading absorbance values
The main operating menu shows the absorbance values for up to 3 active
wavelengths. The menu is reached from any other menu by pressing the ESC
button repeatedly. The display for the third wavelength is reached by turning
the dial clockwise.
As an alternative all 3 wavelengths can be shown in a single display, but limited
to 3 decimals. This alternative is reached by turning the dial clockwise.
3.6 Setting wavelength
The instrument can measure up to 3 wavelengths simultaneously and
wavelength changes can be set at any time.
1 Select main menu Set Wavelength , press OK .

3 Set the value, press OK .
4 The next wavelength λ 2 is now shown. Set the value or turn the
wavelength off, by turning the dial counter clockwise until the value passes
through 19 0 nm. If only one wavel ength is to be used, λ2 and λ3 should be
set to off. Press OK .
The first wavelength λ 1 can never be set to off.
5 Repeat step 4 in the menu Set Wavelength λ 3 .
6 Press ESC to return to the main operating menu.
In UNICORN, the wavelengths are set with the instruction Wavelength in
System Control:Manual:Alarm&Mon .
