4.6 Measuring the Absorbance / % Transmission
4.6.1 General information
The absorbance or transmission respectively is measured without the use of
any methods or profiles. All settings are configured during measurement.
Measuring against
the Reference
absorbance
The absorbance or transmission can alternatively be measured against the
absorbance of the zero adjustment or against a Reference absorbance deter-
mined by yourself (see section 4.6.3 M
EASURING AGAINST THE REFERENCE
ABSORBANCE).
4.6.2 Measuring the absorbance or transmission
The settings of the last measure-
ment are active.
1 Using [Wavelength], change the
wavelength as necessary.
2 Using [Absorbance] <–> [Trans-
mission], you can switch over
between absorbance and trans-
mission measurement.
3 If necessary, use or measure a
reference measurement with [Ref-
erence] (see section 4.6.3).
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.
