fluid such as blood or saline, so the catheter must be in a conductive fluid to use this
feature.

Catheter Calibration Tab

The Catheter Calibration screen allows the user to electronically calibrate the pressure,
volume, and ECG signals.
Pressure
Balance Locked/Unlocked Button
Use the Balance Locked/Unlocked button to unlock the balance controls.
The button automatically locks after 60 seconds of inactivity within the balance controls
interface.
Pressure 1/Pressure 2
The Pressure 1 and Pressure 2 scales graphically display the currently measured
pressure from −25 mmHg to 200 mmHg.
This number is also numerically displayed. The calculation of the pressure value is based
upon the system's scale of 1V/100mmHg. The system provides 5V excitation to
transducers assumed to have a sensitivity of 5μV/V/mmHg. (See "Theory of Operation –
®
Strain Gauge Pressure Transducers.") The system is designed to use Millar Mikro-Tip
pressure transducers with 1000 ohms input impedance and 1000 ohms output impedance.
All Millar Mikro-Tip pressure transducers are factory-calibrated to meet these standards.
