Page 27: Port Assignments
All ports of the 807 Dosing Unit can be used differently (see Chapter 4.4, page 20). This is an important precondition for complex liquid handling tasks. Titrandos use a standard port allocation which is the most suitable for titration tasks. ￭￭￭￭￭￭￭￭ 800 Dosino... -

Page 37: Handling And Maintenance
General information 6.1.1 Care In contrast to the dosing units, the 800 Dosino requires no special care. Take care to ensure however that it not exposed to any excessive contami- nation nor to any corrosive influences. These could under certain circum- stances result in functional disruptions and a reduction in the service life of the inherently sturdy mechanics and electronics. -
