• Now prepare the sample changer with the sample beakers. Place the
sample beakers on a sample rack and place this on the sample
changer. The sample changer will automatically recognize which rack is
in position when it is initialized. This is done by pressing the
<MAN CONTROL> key on the Titroprocessor and then the [Sample
changer]
softkey.
• Initialize the sample changer by pressing the [Reset] softkey. This
should be carried out each time a sample rack is exchanged.
After the sample changer has moved to its starting position the correct
rack name should be shown in the sample changer dialog window. If
this is not the case then the sample changer and the rack definitions
must first be configured, see page 39ff.

• Now use the softkeys [Shift left], [Shift right], [Lift
up] [Lift down]
to rotate the sample rack so that a rinsing beaker
is positioned under the titrating head which has been fitted up. Please
note that the rack can only be rotated when the lift (or both lifts for
models with two lifts) is located in the upper rotate position defined in
the configuration.
• Move the lift to the working position and prepare the buret units as
described under 'Single determinations ' (page 83).
• The entry 'Sample pos.' can be found on the main page. This
determines the first rack position in the sample series. The beaker
position which contains the first sample should be entered here. This
must not necessarily be position 1.
• Initialize the statistics (Statistics 'rst') in order to clear the
working memory and create enough space for the determination data of
the sample series.
• All necessary settings have now been made. Press the <START> key
to start the sample series.
