List of Error Codes
Error code
Cause
How to correct
Er1
Inflation error
•
When the pressure does not exceed 15
mmHg after operating a pump for 15 seconds
from the start of inflation
•
When the inflation does not reach the set
pressure of the arm cuff within the specified
time after starting the inflation
•
If the connector of rubber tube connecting the
arm cuff and the main unit is loose, connect them
correctly, then measure.
•
If the rubber tube connecting the arm cuff and the
main unit is bent, stretch it, then measure.
•
If the arm cuff is wrapped loosely, wrap it correctly,
then measure.
Er2
Deflation error
•
When the deflation speed is too fast during
the measurement
•
When the deflation speed is too slow during
the measurement
•
When the measurement does not end
within the specified time after starting the
measurement
•
When the pressure is applied more than 5
minutes
Er3
Overpressure error
•
The arm cuff pressure exceeded 299 mmHg.
•
If the rubber tube connecting the arm cuff and the
main unit is bent, stretch it, then measure.
Er4
Insufficient inflation error
•
Blood pressure could not be measured due
to insufficient inflation after the measurement
ends.
•
If the measurement is made by setting P-SET to
“AUTO”, ask the patient not move his/her arm or
body during the inflation.
•
When setting the P-SET to “AUTO”, turn the Volume
counterclockwise as far as it goes until you can hear
the click sound.
•
Set the P-SET to 30 to 40 mmHg higher than the
systolic pressure of the patient, then measure.
Er5
Indeterminable blood pressure error
•
Blood pressure could not be measured even
when the arm cuff pressure reached the
specified pressure.
•
If the arm cuff is wrapped loosely, wrap it correctly,
then measure.
Er6
Pulse wave small error
•
Pulse wave was too small.
•
If the arm cuff is wrapped loosely, wrap it correctly,
then measure.
•
Do not wrap the arm cuff over a thick cloth or by
rolling up the jacket or shirt.
Er7
Measurement error
•
Relationship between systolic and diastolic
pressures was abnormal.
•
Check if the patient has an arrhythmia.
•
Ask the patient not to move his/her arm or body
during the measurement.
Er8
Pulse rate error
•
Pule rate did not stay within the range of 30
to 199 beats/min.
Er9
Device error
•
There is a problem with the main unit of the
blood pressure monitor.
•
Contact the dealer where you purchased the unit or
the nearest OMRON dealer.
