4.5.3 Measuring the concentration
From the second concentration measurement, the data of the program
last used is automatically displayed here.
With <> <> you can quickly switch between the ten programs last
used.
To select a program, you can as an alternative also read in the program
number of an analysis specification with a bar code reader (see
section 8.2). The following step three is skipped. You can directly start
measuring.
The program number of the test is given in the analysis specification, in
the list of available programs and, with some tests, on the packing of
the test (under the bar code).
If a program number is selected that requires a measured blank value,
the menu automatically guides to the blank value measurement.
1 If necessary, press the <M> key several times until the mea-
sured parameter Concentration is selected.
2 Open the Program number display with <PROG>,
enter the required program number with the number keys and
confirm with <START/ENTER>.
or (from the second concentration measurement):
Select a program out of the last ten programs with <> <>.
The program data is displayed.
