sensor should be in line with the top of the patient's ear. Incorrect position can
result in erroneous pressure readings.
13.3.2.
IBP sensor Zero
To obtain accurate pressure readings, the monitor requires a valid zero point. Zeroing
the sensor at the hospital's specified frequency, and zeroing must be performed in the
following cases:
Every time reconnecting IBP sensor and IBP sensor cable.
The monitor needs restart.
Suspecting the monitor's pressure reading is inaccurate.
When the monitor displays the message

, Please refer to the
following steps to calibrating zero:
1.
Connecting IBP sensor, sensor cable and module.
2.
Closing the 3-way stopcock (nearby the sensor end) to the patient's valve,
and let the sensor pass through the 3-way stopcock to the atmosphere.
3.
Zeroing the sensor using one way from the following methods:
Select the parameter area of the pressure (e.g. ART) and select the

the pressure to zeroing.
4.
After successful zero, close the valve to the atmosphere and open the
valve to the patient. During zero process, when pressure fluctuation or
the pressure exceeds the zero pressure range, it may fail. If fails, the
processing method as follows:
Check valve position of the 3-way stopcock near the sensor end
for ensure access to the atmosphere.
Perform zero against. Do not shake the IBP sensor and tubing
during zero calibration.
