4 - Preconditioning (only for methods with conditioning)
In methods that contain commands with switched-on conditioning and in which
the option Automatic conditioning is switched on in the START command then pre-
conditioning will start for all these commands. Preconditioning does not belong to
the determination itself and does not increase any counter (
Sample number , Statis-
tics ).
• Conditioning requirement not fulfilled
After the start of preconditioning the status changes to COND BUSY . In
this status conditioning can be started with [Start] even though the
conditioning requirement has not been fulfilled. Conditioning can also
be canceled with
[Stop] or interrupted with [Hold] and then continued
with [Cont] . If an error occurs during conditioning then neither the Error
track nor the Exit track will be carried out.
• Conditioning requirement fulfilled
If the conditioning requirement has been fulfilled then the status
changes to
COND READY . In this status the determination can be
started with [Start] . Conditioning can also be canceled with [Stop] or
interrupted with [Hold] and then continued with [Cont] . The condition-
ing requirement will continue to be monitored continuously until the
determination has been started.
5 - Start method
At the start of the method the following checks and actions are triggered:
• Check sample data
Checks that the entered Sample data corresponds to that defined in
the Method variables and is valid.
• Assign determination ID
An unambiguous determination ID is assigned for the determination.
• Reserve device (module)
The devices (or their functional units) used by the device-dependent
commands contained in the method are reserved for the duration of
the determination, i.e. they cannot be used in other workplaces nor
can they be operated manually.
• Increment sample number
The Sample number is increased by +1 .
• Increment statistics counter
If statistics has been switched on in both the START command and on
the tab Single determinations then the statistics counter is increased by
+1 . If a new method is loaded or if the statistics counter agrees with
the set counter then the current statistical data will first be deleted and
the statistics counter reset to 0 .
6 - Main run
When processing the loaded method the following actions can be carried out:
• Process main track
After the start of the Main track the status changes to BUSY . The com-
mands of the main track and the other tracks that it calls up are proc-
essed in sequence. If the main track calls up tracks that are not free
then a pause will be made until these tracks can be started.
• Interrupt and continue run
A running determination can be interrupted at any time with [Hold] and
then continued with [Cont] . All the active tracks will be stopped and
continued together.
