Status Bar
The status bar displays the coordinates of the mouse cursor if positioned on the
curve graph.
If a selection was made, the X-coordinates of the selection (begin, end and width)
is displayed.

Function
The pressure viewer draws the curves graphs that are stored in the files
*.pmd.zip, which are produced by the PMP option.
Each file is associated with the pipetting cycle of a specific pipetting tip.
If several files are opened each curve graph is drawn in a different color.
How to View
Curve Graphs
Use one of the above mentioned methods to open one or several of these files to
evaluate the pressure gradient of the corresponding pipetting cycle.
Note: The pressure curve files can also be opened or added by dragging and
dropping the file from the Windows explorer to the main window of the pressure
viewer.
While loading one or several pressure curve files a Progress dialog appears
showing a progress bar. The dialog also gives information on the file name being
loaded and the actual number of files as well as the total number of files to be
loaded.
To cancel the process, click on Cancel in this dialog.
Select a part of the curve with the left mouse button to define the zoom section.
If only a part of the curve graph is displayed due to a zoomed selection, horizontal
and vertical sliders appear and enable you to scroll along the curve graph.
Evaluation of Curve Graph
One or several curve graphs show the pressure gradient of the corresponding file.
If the axes are shown, they represent the following absolute values.
• X-Axis
– The X-axis represents the time in ADC (Analog to Digital Converter) steps.
• One ADC step equals 2 ms.
• Y-Axis
Before each measurement the y-axis value is set to zero, i.e. 0 pADC equals
ambient pressure.
