5. Repeat steps 3 to 4 to calibrate further transducer cables.
6. If auto-scaling of the display of the pressure channel is not required, adjust
the display range in the main menu "IBP" ► "Settings" (for further
information see chapter 7.2.4 IBP, p. 152).
The message “NON CAL” in the parameter field and/or in the curve field
indicates an uncalibrated measuring channel (P {measuring channel}),. No
alarm is triggered and no measuring channel trend is recorded.
Atmospheric pressure must be present on the transducer during calibration.
Calibration is completed after approx. 5 seconds. In case of an error, a technical
alarm is triggered. In this case, sources of error are to be eliminated and the
calibrating measures to be repeated, if necessary.
If no transducer is connected, or if the transducer is loose, the technical alarm
"IBP P {measuring channel} sensor loose" is triggered. The prerequisite in this
case is that a transducer has already been connected and calibrated previously.
The shunt valve of transducer should be positioned approximately at the level of
the right atrium (approximately in the area of the middle axillary line).
During cranial pressure measurement, the shunt valve should be aligned with
the upper edge of the ear. Any deviation from the prescribed position may
invalidate the values.
The hydraulic system of the transducer must be de-aerated before invasive
pressure measurement is performed. Please read and follow the operating
instructions and accompanying documents of the respective manufacturer.
