Patient Monitor User Manual
NOTE:
It is the responsibility of the user to ensure that a zero procedure has recently been done
on the transducer: otherwise there will be no recent, valid zero value for the instrument to
use, which may result in inaccurate measurement results.
Zero Calibration of Transducer
Select CH1, and then IBP1 returns to zero. Select CH2, and then IBP2 returns to zero.
1
Turn off the patient stopcock before you start the zero procedure.
2
The transducer must be vented to atmospheric pressure before the zero procedure.
3
The transducer should be placed at the same height level with the heart,
approximately mid-axillary line.
4
Zero procedure should be performed before the monitoring starts, and at least once a
day after each disconnect-and-connect of the cable.
The prompt information related to zero calibration, take CH1 for example.
"CH1 ZERO SUCCESS!"
Indicate that zero calibration is over，so you can turn off the stopcock that was open to
atmospheric pressure, and turn on the patient stopcock.
"CH1 ZERO FAIL!"
Make sure that the transducer is not attached to the patient.
"CH1 SENSOR OFF, FAIL!"
Make sure that transducer is not off, and then proceed zeroing.
"IN DEMO, FAIL!"
Make sure that the monitor is not in DEMO mode. Contact service technician if
necessary.
"PRESSURE OVER RANGE, FAIL!"
Make sure that the stopcock is vented to atmosphere. If the problem persists, please
contact service technician.
IBP Calibration
Press the IBP PRESSURE CALIBRATE button on the IBP (1, 2) SELECT menu to call up the
IBP PRESSURE CALIBRATE menu as shown below:
