Measuring the concentration
To select a program, you can as an alternative also read in the program num-
ber 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 (un-
der the bar code).
