2.3 Composition of a method
32 Metrohm 838 Advanced Sample Processor, Operation
2.3.7 Programming of sequences
The creation of sequences is done in the submenus
'>start sequence'
,
'>sample sequence'
and
'>final sequence'
, which are accessible via the
parameter menu.
Each sequence is organized in lines. In each line, the commands that
are on the numerical keypad as alternate functions can be used to enter
commands. After selecting a command and entering the necessary
data, the entry is accepted with . The line number is visible in
the display. 99 lines per sequence are possible.
Navigation in a sequence is accomplished as in the other menus. In
addition the and keys can be used.
INSERT
adds a new command line above the current line in a
sequence. It is automatically occupied by the "NOP" command that has
no function. The following lines are shifted one line downwards.
DELETE
deletes the current line in a sequence. The following lines
are shifted one line upwards.
The "LEARN" mode is available for the easy entry of parameters.
Furthermore the "TRACE" function can be used to execute every com-
mand line step by step.
2.3.8 LEARN mode
HOLD
LEARN When editing a method, the parameters of a command are most easily
determined experimentally, i.e. by manual execution, and it is for this
reason that certain commands are "teachable". The LEARN function
makes the manual execution of particular changer commands possible
during the editing of a sequence. The resulting parameters (for exam-
ple, the lift position or the status of the input lines) can be taken over in
the current command line. The LEARN function can be used repeti-
tively. When times or volumes are "learned", the repetitive values are
added up.
Procedure for creating a method
• Enter a command or select an existing command line.
• Press the key.
− Function is started, "LEARN" LED lights up.
− Press the key.
− Function is stopped, "LEARN" LED blinks.
− With the key, accept the value
(or re-start the LEARN function).
"LEARN" LED goes out, edit next command line.
Die LEARN-Funktion steht für folgende Befehle zur Verfügung:
