Key Normal state Edit mode
STOP
Stop process and peripheral
instruments
• The <STOP> key terminates a
method.
• Any peripheral instruments that are
connected (e.g. 709 IC Pump) are
not automatically stopped. In
'>manual stop options' , a sub-
menu of the Parameter menu, you
can specify what signal or data is to
be transmitted via the interface
involved (remote or RS232) during
manual activation of the <STOP>
key. The connected instrument can
be halted or if necessary, initialized
(see section 4.3.2).
• During a manual halt of a sample
series with <STOP>, the end
sequence of the method will not be
executed.
• In the normal state the <STOP>
key also stops the pump. The
'>manual stop options'
for con-
nected peripheral instruments are
also effective in the normal state.
Stop editing
• <STOP> causes the editing to
abort and the instrument to return
to the normal state. (exception:
Process sequences).
HOLD
LEARN Interrupt Process
• The <HOLD> key interrupts the
processing of a method. However
connected peripheral instruments
(e.g. 709 IC Pump) are not halted.
Only method processing is inter-
rupted. In the "HOLD" state a
method can be completely halted
with <STOP> or continued with
the next command in line by
pressing <START>.
• After quitting an error message
during method processing the IC
Sample Processor automatically
goes into the "HOLD" state.
Switch on LEARN mode
• The <LEARN> key serves to start
the LEARN mode. This mode is
provided for easier editing of proc-
ess sequences. It allows direct
acceptance of a parameter value
that has been set by manual con-
trol. The LEARN mode is available
for the following commands:
LIFT, PUMP, SCN, WAIT
• Details concerning the LEARN
mode see section 4.3.4.
