Explanation of
photometric
measurements
The basic procedure is largely the same for all photometric mea
-
surements and is briefly outlined below. A photometric measure
-
ment consists of the following steps:
Step 1: Zero measurement
Step 2: The actual measurement
Step 3: Display and storage of the measured results. For de
-
tails on the result screen, see example on
.
The methods differ mainly in the following points:
Different reagents are required depending on the method.
Some methods require a reaction time. If this is the case for
the selected method, this will be indicated on the screen
during the measurement.
Some methods (e.g. combined chlorine) perform two different
measurements in a row and calculate the required values
from them.
Starting a
measurement
To start a measurement, select the corresponding method from the
main screen. If it is not available there, select it from the method
catalogue.
The measurement itself is menu-driven. Follow the instructions on
the screen.
