3.3 Memory Initialization

The system memory can be initialized to set default parameters
when required (e.g. in the case of mal-functions). For this purpose
press all keys while the sample changer is switched on.

It is recommended to execute an initialization before the first instal-
lation of the sample changer.

3.4 Configuration Procedure

The

Configuration Procedure starts when the instrument is

switched on with pressing simultaneously. The method is
being selected and working, rinsing and shift heights are defined
and assigned to the selected rack type. Additionally, the stirrer
speed can be defined.

If the 760 Sample Changer is used for the first time, the lift posi-
tions have to be adapted to the selected rack type. This applies
also if a new rack type is inserted for the first time.

Empty beakers with a stirrer bar if necessary should be used for
the definition of the lift positions. Additionally, the foil holder has to
be used without Al foil if the Sample Changer is being set up for
Karl Fischer titration.

The working position should be defined in such a way that the
connected electrode tip stands in the center of the sample. The
shift position should allow a free rotation of the sample rack. In the
rinsing position, the aspiration tip should touch the bottom of the
sample beaker. If no rinsing step is necessary (method 1 and 2),
no rinsing position has to be defined.

In order to proceed to the next point in the configuration procedure,
must be pressed. This accepts the current setting.
is pressed in order to cancel a setting. The configuration
procedure is terminated by pressing again.
