4.5 Measuring the Absorbance / % Transmission
4.5.1 General information
The absorbance or transmission respectively is measured without the use of
any methods or profiles. All settings are configured during measurement.
The absorbance or transmission can alternatively be measured against the
absorbance of the zero adjustment or against a Reference absorbance
determined by yourself.

1 Using [Wavelength], change the
wavelength as necessary.
2 Using [Absorbance] <–>
[Transmission], you can switch
over between absorbance and
transmission measurement.

3 If necessary, use a reference
measurement with [Reference] or
measure a new one.
4 Depending on the type, insert the
cell as follows:
Round cell:
Insert the round cell in the round
cell shaft so it touches the bottom.
If the inner turn-up lid is opened
too wide, a message prompts you
to close the inner turn-up lid.
