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 Label> 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 pop-up key.
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 <Press
Label>
menu.
2 In the Setup <Press Label> menu, (for example ABP) select Scale.
3 Select a value from the pop-up list:
– a positive value sets the top gridline. The bottom gridline is set at zero.
– a negative value sets the bottom gridline. The middle gridline is set at zero.
Optimizing the Waveform
In the Setup <Press Label> menu, select Optimum Scale to let the monitor select the best minimum
and maximum scales for the current wave.
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.
