4.5.6 Measuring the absorbance/transmission
The transmission measurement is not described separately in the fol-
lowing example as it operates in exactly the same way as the absor-
bance measurement. The result of the measurement is displayed in %
Transmission.
1 Press the <M> key (long pressure) repeatedly until the Pho-
tometry measuring mode is selected.
2 Press the <M> key (short pressure) repeatedly until the mea-
sured variable, Absorbance or % Transmission is selected.
3 Select the cell diameter with <> <> and confirm with
<START/ENTER>.
4 Select the wavelength with <> <> and confirm with
<START/ENTER>.
5 Clean the cell (see section 5.2.2).
6 Insert the cell (see section 4.2).
7 Start the measurement with <START/ENTER>.
The measurement result is displayed when the measurement
is finished.
