Functioning of the beaker sensor
If the beaker sensor of the robotic arm is activated, then the lift of the Sample
Processor will move automatically into its work position after a MOVE com-
mand. The presence of the sample vessel is checked by the robotic arm
setting down on top of it.
No separate LIFT command is required in such cases.
Note
The work position of the lift must be configured in such a way that the
robotic arm is in place on the sample vessel. The robotic arm must bend
very slightly while doing so, so that the Piezo sensor will generate a signal.
3.8 Installing rinsing and aspiration equipment
Various tubings are necessary for rinsing the electrode and the dosing tips
as well as for aspirating the sample solution after the titration. First, mount
the tubings on the distributor.
Mounting the rinsing and aspiration tubings
Install the tubings as follows:
