robotic arm and pressure can be applied to force the sample solution
through the filter.
3.2 Adjusting rack and robotic arm
The Luer adapter on the robotic arm must be positioned precisely for pick-
ing up membrane filters or syringe needles. In order to ensure this, it is
necessary to align the sample rack and the robotic arm precisely in relation
to one another.
The tiamo control software allows the user to enter a so-called "offset" in
the configuration of a robotic arm or a sample rack (rack table). This
allows fine-tuning to be performed.
The adjustment needs to be made when sample racks with inserts for
membrane filters (e.g. 6.2068.020 and 6.2068.030) are used. These
inserts feature a "positioning reticule". This is the adjusting position.
Preparing the Sample Processor
Proceed as follows:
1 Put the sample rack in place.
The insert (or the inserts) for membrane filters must be in place.
2 Start tiamo.
3 Open the manual control with a click on the corresponding symbol in
the toolbar.
4 Select Tower 1 under Sample changer ▶ 815_1.
5 Click on [Initialize rack].
The sample rack moves into starting position. The rack code is read
and the rack table is loaded.
Moving to the positioning reticle
Proceed as follows:
1 In the Manual control in tiamo, switch to the Move tab.
