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.
