Metrohm Sample Processor, Introduction
Editing and sequence control
INSERT
DELETE
When editing a method sequence the <INSERT> and <DELETE>
keys are used to insert or delete a command line.
RESET
CLEAR
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.
QUIT
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-

SAMPLE
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.

MOVE
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.
The <SELECT> key is used to select the tower.
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 or with the <DEF> key.
Important:
For safety reasons it is only possible to rotate the sample rack when
the lift or both lifts are located in the shifting position or above it. Dur-
ing a rack rotation the lift (or both lifts) are automatically first raised to
the predefined shift height.
