Selecting a Filter Frequency
When noise and other interference appears on the pressure waveform, you can
adjust the filter frequency to minimize its effect.
A higher filter frequency shows greater detail, but can also produce more artifact.
A lower filter frequency smooths the waveform and may help diagnose transducer
or catheter problems such as under damping or ringing.
The filter frequency may be set within the range of 3 to 40 Hz.
Restoring User-Defined Settings
With the Restore Settings feature, you can restore the user-configurable settings
to the defaults previously stored as user settings. User-configurable settings are
