6 Measuring the absorbance/transmission
If a cell is left in the cell shaft while you switch
between the absorbance and transmission
measurement, you have to insert the cell
once again to start the measurement.
The transmission measurement is not de-
scribed separately in the following example as
it operates in exactly the same way as the ab-
sorbance measurement. However, the result
of the measurement is displayed as % Trans-
mission instead of A for Absorbance.
