Sensor signal is poor or too weak. Check the patient's condition,
and place the sensor in a suitable position. If the failure persists,
replace the sensor.
NIBP
NIBP Comm. Stop
H
NIBP module failure, or communication failure between the
module and the host; please restart the device.
NIBP Comm. Error
H
NIBP Selfcheck error

NIBP system error
H
If failure occurs during measurement, the system can’t analyze
and calculate. Check the patient's condition, check the
connections or replace the cuff, and then re-test.
Measurement timeout
L
Cuff type error
L
The used cuff does not match the set patient category. Verify the
patient category and replace the cuff.
NIBP
Cuff loose or no cuff
L
NIBP cuff isn’t placed or connected properly, or there is gas leak.
Cuff leak
L
Check cuff and inflation tube.
Air pressure error
L
Ambient atmospheric pressure is abnormal. Confirm that the
environment complies with the monitor's specifications, and
check whether there are special reasons affecting ambient
pressure.
NIBP over range
L
The measured blood pressure of the patient exceeds the
measuring range.
NIBP signal weak
L
Patient’s pulse may be weak or cuff is too loose. Check the
condition of the patient, and place the cuff in a suitable position.
If the failure persists, replace the cuff.
NIBP signal unstable
L
Excessive movement may result in too much motion artifact or
interference in the signal during measurement.
NIBP signal saturated
L
Motion signal amplitude is too large due to movement and other
reasons.
NIBP over pressure
L
Cuff overpressure, and gas blockage may occur; check the gas
path, and then re-measure.
Module reset failed
L
NIBP module reset error; check the gas path is blocked, and then
