PLACEMENT SCREEN
The placement screen (see Figure 4.4) displays real-time operating data for the system.
The screen displays the placement signal and motor current waveforms as well as the
maximum/minimum and average values for each waveform in the central display area of the
screen.
Use the
DISPLAY
soft button to navigate to the placement screen.

Figure 4.4 Placement Screen
Figure 4.4 shows two time-based waveform signals from different sources.
• Placement signal waveform
• Motor current waveform
PLACEMENT SIGNAL WAVEFORM
The placement signal waveform displays a pressure measurement from the differential pressure
sensor. The scale for the placement signal waveform is displayed to the left of the waveform. The
default scaling is -20 to 60 mmHg. The scale can be adjusted in increments of 10 mmHg for a
maximum range of -60 to 100 mmHg or a minimum range of 0 to 40 mmHg.
To the right of the waveform is a display that labels the waveform, provides the units of
measurement, and shows the maximum and minimum values and the average value from the
samples received. At the bottom of that window is the time scale, which you can set by pressing
the
DISPLAY
soft button.
