are also executed via the interfaces to stop instruments that are
connected or to initiate other actions.
With <HOLD> the processing of a method can be interrupted. The
command that is active at this point is immediately interrupted as a
result. <START> continues the active sequence beginning with the
command immediately following the one interrupted. Any periph-
eral instrument connected is not stopped with the <HOLD> key.
<CLEAR> interrupts a sample series at the end of a currently ac-
tive sequence (soft break). The sample currently being processed
will be completed.
<QUIT> interrupts the command currently being executed and
starts the next command line in the sequence.
If errors occur during the sample series, the corresponding error
message
is displayed and must be acknowledged with <QUIT>.
The changer then goes into the HOLD status (see above). After
remedying the error, <START> resumes the sequence or <STOP>
halts it entirely.
3.5.4 POWERUP Method
When the sample changer is switched on, the sample rack and the
titration heads are brought into the rest position. Thus, electrodes
are moved out of the conditioning vessel eventually. To bring them
back into the conditioning vessel, the "POWERUP" method can be
used. This method is started automatically, when the sample
changer is switched on.
Create a method that contains the command sequence which
should be worked off, when the sample changer is switched on.
Store this method under the name "POWERUP" (see page 93).
