Check the settings of the connected dosing device on the

'MANUAL

CONTROL' page. If no entries have been made under 'Reagent' and
'Concentr.' then no reagent check will be carried out. If different reagents are
often used this is probably the correct setting, otherwise please see page
54.
If the buret of the connected dosing device is equipped with the standard
tubing (dosing tubing 400 x 2 mm, …), then 'Default' must be entered
under Tubing. If the buret unit is not equipped with standard tubing then it
must be configured accordingly, see page 47ff.

[Prepare]

Use the cursor keys to select the required dosing device, make sure
that the buret tip of the attached buret unit is located in a rinsing beaker
and press the [Prepare] softkey.

All the tubing and the cylinder of the buret unit are now rinsed with a
sufficiently large amount of reagent to ensure that the buret unit is properly
filled without any air bubbles.

After the sensor and the buret tip have been rinsed with a suitable
solvent the Titroprocessor is set up and the sample can be positioned.

The

key can now be used to start the determination.
