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 deter-
mined by yourself.

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