6.5 Diagnosis
711 Liquino, Instructions for use 156
Provided that the memory card remains inserted during the whole test proce-
dure and that the mains switch is not operated the test is non-destructive, i.e.
the memory card contents will not be altered by the test.
If it is possible to assume that the memory card is functioning perfectly and
that it does not explicitly need to be tested then the test described under
section 5.4.13 can be carried out instead of this test. That test takes less than
2 seconds and provides information about whether the memory card control
contained in the 711 Liquino is functioning properly, but no information about
the memory card itself.
• Prepare instrument for diagnosis (see Sect. 6.5.3).

responds. Subsequently the address of the last address to respond
will appear in the display. Because the test does not know the size of
the memory card the operator must check at this point whether the
checked item is functioning properly or not by means of the BREAK
ADDRESS.
