Dosing control

The <DOS> key serves for
the control of Dosimats
and Dosinos. These are
controlled via the "External
Bus" connector.

The first parameter is for
the selection of the dosing
unit. The second parame-
ter represents the function.

In addition to dosing vol-
ume and the fill command,
the functions specific to
the Dosino 'release', 'pre-
pare', 'empty', 'eject', 'ad-
just' and 'level' can also be
executed.

The dosing and filling
speed can be set in the
parameter menu or with
the <DEF> key.

Numerical entry ('6')
or
Dosing control

In a sequence you can not
only add a certain volume
under process control, it is
also possible to initiate the
burette filling with Dosimats
or initiate the designated
functions with Dosinos as
there are: filling, emptying,
preparation, release,
ejecting, adjusting or level
of the exchange unit.

SCAN

Display input signals

Display of the incoming
signal or data on the re-
mote or RS interface. This
function serves to control
the data communication or
states of connected in-
struments.

The first parameter repre-
sents the interface selec-
tion. The signals for data
being received at that
moment are displayed as
the second parameter.

If the parallel remote in-
terface (Rm) is selected,
the signal states of the in-
coming remote lines are
displayed in binary form
(1=line active, 0=line inac-
tive). Further details relat-
ing to this see page 119ff.

Numerical entry ('1')
or
Scan input signals

In a sequence the SCAN
command causes method
processing to stop until the
predefined bit pattern (with
the remote interface) or the
given character string (with
the RS232 interface) is re-
ceived.

Predefined bit patterns are
available for the remote
interface and can be se-
lected via simple short-
names (e.g. "ready1" or
"end2").
