5 Methods and determinations
5.1 General
A method must be loaded in the working memory in order to carry out a
determination on a sample. The creation of a method for each application is
recommended; this should be stored in the internal memory or on a data
card so that it can be loaded and used whenever required.
A method consists of a sequence of different commands which are carried
out when a sample is processed. The commands may be titration mode
commands, measuring mode commands, sample changer commands or
other commands. Up to five titration or measuring modes can be contained
in one method. A total of 99 commands can be carried out in sequence.
The easiest way of loading methods is with the
<METHOD> key. This is
also possible in the method editor via the [File] softkey or in the file
manager with the key sequence [Copy to] 'Working memory'. If the
Auto start function is used methods can also be loaded automatically from
the sample silo.
If a sample changer is used (Auto start ‘on’) then a start sequence
and/or a closing sequence can be defined. A start sequence(OMOVE ...
)OMOVE
is carried out with the first sample of a series. A closing
sequence(CMOVE ... )CMOVE is carried out with the last sample of a
series.
Conditional command sequences (CASE structures) can be defined; these
are only carried out when a particular condition has been fulfilled.
5.2 Method editor
The method editor is called up from the main page by pressing the [Edit
method]
softkey.
