10.1 Test Sequences
The following flowchart is representative of all test sequences.
The control test sequence is started automatically in the back-
ground, during the course of which all preliminary tests are exe-
cuted which are required for a safe test sequence.
The number and type of test steps varies in the visible part of the test
sequence depending upon which standard has been selected.
How the various test steps included in the test sequences can be
accessed and modified is described in section 7.4.3 (factory de-
fault setting: read only). The test sequences are described in de-
tail in section 7.4.3.
