Measuring against the Reference absorbance

Each time the photometer is switched on, the absorbance or transmission is
measured against the absorbance of the zero adjustment as a basis. You
can, however, also determine a

Reference absorbance

and use it as the

basis.

The

Reference absorbance

refers to the adjusted wavelength. The measured

value remains stored until



the instrument is switched off



the cell type is changed



the wavelength is changed



a new reference value is measured



it is deleted manually (

Single and multiple

determination

The Reference absorbance can be determined with single or multiple deter-
mination. With multiple determination, the mean value is calculated as the
median from the individual measured values.
