Manual Control Mode
When using more than one PPS2-System, connected via USB cable, one main window tab
page will be available for each PPS2 connected. The tab slider will show the serial number
of the deices. The pumps can be operated independently from each other. Only the “Stop”
button will affect all connected pumps, all other control functions are independent.
The intended use for the PPS2-System is the perfusion of a biological sample on a MEA and
the aspiration of the waste solution. To avoid flooding of the amplifier, the flow rate of the
outlet must always be higher than the flow rate of the inlet. Select the check box “Fixed
Speed Ratio Waste to Perfusion” in %. Via slider or up-down box you can choose the
relation between the velocity of the waste and the perfusion pump. If the “Fixed Speed Ratio”
function is active, both pump speeds will remain at the same relative relation, and only the
control slider for the perfusion pump is active.
The green color of the buttons above the “On” and “Off” buttons indicate that the respective
pump is running. Additionally the speed symbol is rotating.
