12 Monitoring Invasive Pressure Adjusting the Calibration Factor
154
If you are measuring pressures with more than one measuring device, using the Zero SmartKey to
initiate the zeroing calls up a list of all active pressures. Select the pressure you want to zero or select
All Press to zero all pressures simultaneously.
Troubleshooting the Zero
The status line lists the probable cause of an unsuccessful zero:
Adjusting the Calibration Factor
Each time you use a reusable transducer, compare the calibration factor written on your transducer
with the calibration factor shown on the monitor. To ensure accurate measurement, they must be the
same.
1 In the Setup <Press> menu, select Cal. Factor.
If the value here does
not match that on the transducer, select the corresponding value from the
list now in accordance with your hospital’s procedure.
2 To confirm you want to use the new calibration factor, select the Confirm popup.
Displaying a Mean Pressure Value Only
Use this when you want to see only the mean pressure.
♦ In the pressure’s setup menu, select Mean Only. Toggle between On to display mean pressure
value only, and
Off to display all pressure values (systolic, diastolic and mean).
Changing the Pressure Wave Scale
1 Select the label of the pressure wave whose scale you want to set to enter the Setup menu.
2 In the Setup <Press> menu, (for example ABP) select Scale.
Message Corrective Action
unable to zero -
equipment
malfunction
The hardware is faulty. Contact your service personnel.
unable to zero -
excessive offset
Make sure the transducer is vented to air and try again. If this fails, the hardware
may be faulty. Replace the adapter cable and try again. If it fails, replace the
transducer and try again. If it still fails, contact your service personnel.
unable to zero -
unstable signal
unable to zero -
no transducer
Make sure that the transducer is connected and try again. If this fails, exchange
the adapter cable and try again. If this fails, exchange the transducer.
unable to zero -
pulsatile
pressure
Make sure that the transducer is vented to air, not to the patient, and try again.
unable to zero -
timed out
Try pressing the Zero key again. If this fails, replace the transducer and adapter
cable and contact your service personnel.

Pressure measurement is switched off. To switch it on, in the Setup Pressure
menu, select the pressure’s label.
