Secondary functions of the absorbance screen
Autozero on

changes
This function results in an autozero each time a
wavelength change is requested. If you disable this
function, significant changes in measured absorbance
can occur after each wavelength change. Selecting “to
zero” sets the signal level to zero. Selecting “to
baseline” maintains the previous baseline level when
the wavelength change is made. The default is “to
zero.”
