3.1 Tutorial
In order to become acquainted with the 730 Sample Changer and
its mode of operation, it is helpful to work through the short Oper-
ating Tutorial. The basic operating steps that are required to pre-
pare the first sample series and run it with a given method are de-
scribed here.
Prerequisites / Preparations
• This operating tutorial can be carried out with all changer varia-
tions (1-tower or 2-tower models). Only tower 1 will be used in
this case. If a swing head is installed, see chapter 3.3 "Swing
Head", page 42.
• It is assumed that the changer is fully installed.
• Connect a Metrohm titration instrument (a Titrino model is a
good choice) to the remote socket (cable 6.2141.020). This tuto-
rial can also be executed as a "dry run" i.e. without a titration in-
strument.
• Choose a simple titration method that you have saved in the
titration instrument or create a new simple method.
• Mount the necessary tubing, an electrode and the rotating noz-
zle or spray nozzles on the titration head on tower 1. Don’t for-
get to mount the splash protection and the plug cover.
• The <ê> and <é> keys can be used to move the lift up or down
for this purpose.

• With the 2-tower model, the <TOWER/SELECT> key changes

ENDSEQ • Install the sample rack. Press the <RESET> or <ENDSEQ>
(+<ENTER>) key. The changer is initialized in this way with
each lift placed in the rest position and the rack is turned until
the rack position 1 is positioned in front of tower 1. In this posi-
tion the magnetic rack code can be read so that the internally
stored rack data (position table, etc.) can be loaded.
This should be done after every rack change.
