After the verification, do press the button again to return to normal working mode, then continue other op-
eration, or the NIBP key will be invalid.

Pressure accuracy verification must be operated by technician or equipment manager. Doctors and nurses
are not allowed to do the verification, it is very dangerous especially when the pressure cuff is still on pa-
tients.

Air Leakage Check
In order to avoid significant error of blood pressure measurement or even no measurement result caused by
air leakage in the pneumatic system including the cuff during measuring, it is recommended to check if there
is leak in the pneumatic system as well.
Please remove the cuff from patient while performing the leakage check.
24.5 IBP Calibration (Optional)
This section is for professional technician only.
Each time connecting transducer or selecting another measuring label, then prompt displays on the screen.
There is two methods for calibration: zero calibration and pressure value calibration.
Calibration procedure:
1. On calibration window, press “Zero” button to perform zero calibration, then “Zeroing OK” will display on the
window.
The following message may may appear on the window during calibration:
• Probe off, unable to zero
• Probe off, unable to calibrate
• Unstable zero base pressure
• Pressure out of range
• Zeroing OK
2. Expulse all the air from the tube, then adjust the transfusion tube and stopcock (“Off” to the transfusion
tube). Open the dust cap, and ensure the dome touch the air.
3. Zero calibration is required, zero calibration must be done before IBP monitoring, or the IBP readings will not
be accurate.
4. It is recommended that “0 calibration” must be carried out each time before measuring, and at least per-
forming once a day (zero calibration should be performed every time you connecting the plug to the IBP
socket on the monitor), or the inaccuracy will be caused. If using a new IBP transducer, please perform
pressure calibration.
24.6 CO
2
Test
For sidestream CO
2
modules, a calibration is needed every year or when the measured values have a great
deviation. For mainstream CO
2
module, no calibration is needed. Contact your service personnel to calibrate
CO
2
.
24.7 Calibrating AG
Calibrate the AG module every year or when the measured value has a great deviation. Contact your service
personnel to calibrate the AG module.
