15.7 IBP Pressure Zero
The monitor requires a valid zero point to obtain an accurate pressure reading. Please calibrate the sensor according to
the requirements of the hospital (at least once a day). The zero operations must be performed in following conditions:
n
When using a new sensor or sensor cable.
n
When re-connecting the sensor cable and the monitor.
n
When the monitor is restarted.
n
When you doubt that the monitor pressure reading is inaccurate.
Calibration steps are as followings:
1. Turn off the valve from the 3-way stopcock to the patient.
2. The transducer must be vented to atmospheric pressure via the 3-way stopcock.
3. Take the channel 1 as an example, select "IBP SETUP"
→
"IBP PRESSURE ZERO"
→
"CH1 ZERO", then
select it to calibrate.
4.
When the information "CH1 SUCCESSFUL ZERO." apears, close the valve to the atmospheric pressure and
open the valve to the patient.
NOTE:
l
The user should ensure that the sensor has been calibrated before zeroing, otherwise the device hasn't a
valid zero value, which will lead to an inaccurate result.
Troubleshooting for pressure zeroing

IBP1 SENSOR OFF, FAIL.
Make sure that the channel 1 has not the prompt of sensor off, then zero
again, if the problem exists still, please contact the service personnel.
DEMO, FAIL.
Make sure that the monitor is not in DEMO mode, then zero again, if
