Calibrating an AP Transducer
You must calibrate reusable transducers prior to initiating counterpulsation. You should
also recalibrate the transducer during patient use according to your hospital's protocol
to correct drifts that may occur over time. Connect the transducer to the AutoCAT
Series console (see Section 5.1) before calibration.
If it is necessary to Calibrate an AP reusable transducer, follow these steps:
• Open the transducer to air
• Verify AP TRANSDUCER is selected. If not, use the AP SELECT key until
the LED next to XDUCER is lit.
• Press XDUCER ZERO key
• Verify the message "TRANDUCER ZEROED" appears on the display
• Verify the numerical pressure values read "0"
• Close the transducer to air and input 100 mmHg pressure to the transducer.
NOTE: The input pressure must read between 80 and 120mmHG/ 100 mmHg +/- 20 mmHg
to be accepted as a CAL signal)

• Verify input is 100mmHG
• Press APPLY CAL
• Verify message reads "TRANSDUCER CALIBRATED @ 100MMHG"
Setting the CAL level to the factory preset setting
If the CAL is performed incorrectly or must be reset for any reason, use the following
procedure:
• Disconnect the Transducer from the IABP console
• Verify AP TRANSDUCER is selected. If not, use the AP SELECT key until
the LED next to XDUCER is lit.
• Press XDUCER ZERO key
• Verify the message "TRANDUCER ZEROED" appears on the display
• Verify the numerical pressure values read "0"
