14.3 Zeroing the Transducer
To avoid inaccurate pressure readings, the monitor requires a valid zero. Zero the transducer
in accordance with your hospital policy (at least once per day). Zero whenever:
 A new transducer or adapter cable is used.
 You reconnect the transducer cable to the monitor.
 The monitor restarts.
 You doubt the readings.
1. Turn off the stopcock to the patient.
2. Vent the transducer to the atmospheric pressure by turning on the stopcock to the air.
3. In the setup menu for the pressure (e.g. Art), select [Art Zero >>][Zero]. During zero
calibration, the [Zero] button appears dimmed. It recovers after the zero calibration is
completed. To zero all IBP channels, select [Zero IBP] QuickKey, and then select
[Zero All Channels] in the popup menu.
4. After the zero calibration is completed, close the stopcock to the air and open the
stopcock to the patient.
NOTE
z Your hospital policy may recommend that the ICP transducer is zeroed less
frequently than other transducers.
