The <SELECT> key allows to select from a given list of entries when
editing a parameter.
When editing a method sequence the <INSERT> and <DELETE>
keys are used to insert or delete a command line.
The <CLEAR/RESET> key is used to initialize the Sample Processor
and dosing devices. This corresponds to the switching-on process.
During data input the <CLEAR/RESET> key is used to de-
lete an entry or to reset the default value. In text entry mode
the last character is deleted.
During a method sequence the <QUIT> key can be used to termi-
nate the command which is currently being carried out. The following
command is executed.
During data input the <QUIT> key is used to terminate an en-
try. During navigation in a menu the <QUIT> key is used to
exit the active (sub)menu and select the next highest menu
level.
During data input the <ENTER> key is used to accept the entry.
The <SAMPLE> key is used to set the current sample position. This
has to be done before a sample series is run.
At the start of a method this position is assumed to be the first sample
in a series. If no sample position has been set then the Sample Proc-
essor will select rack position 1.
With <MOVE> a vessel or a particular rack position can be moved to
the active tower or a robotic arm can be swung to an external position.
As well as the actual sample beaker a maximum of 16 possible spe-
cial beakers can also be defined. A particular rack position can be
moved to directly by entering the position number (with the numerical
keys).
The direction and speed of rotation can be altered in the parameter
menu.
