Connection of the external control via relay contact
This feature can be used for externally controlled sampling point selection, zeroing
and stand-by, using external potential free relay contacts, see also diagram in $4.4
The relay contacts build a 4-bit binary number:
RC4 - RC3 - RC2 - RC1 open=0,
closed=1.
Let us show this number 'status number'.
