LIST OF ERROR CODES
Trouble
The unit inflates to
abnormally high (low)
pressure.
The monitor cannot
measure blood
pressure.
Measured values are
abnormally high (low).
What to inspect
Is the cuff wrapped correctly?
Is the patient moving during
inflation?
Does this patient have arrhythmia?
Check the patient's condition.
Is the patient moving during the
measurement?
Does the patient have an
arrhythmia?
Is the size of the cuff correct and
is it wrapped correctly?
Is the level of the brachium to
which the cuff is wrapped at the
same level as the heart?
How to correct
Wrap the cuff correctly, and
measure again.
(Refer to Page 14 and 15.)
Ask the patient not to move
during measurement, and
measure again.
Set the P-SET to 30 to 40 mmHg
higher than estimated systolic
pressure of the patient, then
measure.
After checking the patient with
the stethoscope refer to the "list
of error codes".
(Refer to Page 28.)
Ask the patient not to move
during measurement, and
measure again.
Set the P-SET to 30 to 40 mmHg
higher than estimated systolic
pressure of the patient, then
measure.
Select the cuff according to the
patient's arm circumference, wrap
it correctly, then measure again.
(Refer to Pages 14 and 15.)
Keep the level of the brachium to
which the cuff is wrapped at the
same level as the heart, then
measure again.
If the unit malfunctions during use, please check the following:
Are the patient’s clothes restricting
normal blood flow to the arm?
Remove the clothing and
measure again.
Error code Explanation
Inflation error
• When the pressure does not exceed 12
mmHg within the set time after the start of
inflation
• When the inflation does not reach the set
cuff pressure within the specified time
after the start of inflation
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 finish
within the specified time after starting the
measurement
Overpressure error
• The cuff pressure exceeded 299 mmHg.
Insufficient inflation error
• Blood pressure could not be measured
due to insufficient inflation level.
Indeterminable blood pressure error
• Blood pressure could not be measured
even when the cuff pressure reached the
specified pressure.
Low pulse level error
• Pulse wave was too small.
Blood pressure error
• Relationship between systolic and dias-
tolic pressures was abnormal.
Pulse rate error
• Pulse rate did not stay within the range of
30 to 199 beats/min.
Device error
• Main unit malfunction.
How to correct
• Confirm that the air tube connecting the cuff and
the main unit is connected securely.
• Confirm that the air flow in the air tube
connecting the cuff and the main unit isn’t
being restricted.
• Confirm that the cuff is wrapped correctly (refer
to pages 14 and 15).
• Check bladder for leaks and, if necessary,
replace the bladder with new one (option).
• Confirm that air flow in the air tube connecting
the cuff and the main unit isn’t being restricted.
• If the measurement is made by setting the P-SET
to "AUTO", ask the patient not to move during
the inflation.
• Confirm that the P-SET is securely set to
"AUTO". Turn the Knob counterclockwise as far
as it goes until you can hear a click sound.
• If the measurement is made by manual inflation
level setting, set the value to 30 to 40 mmHg
higher.
• Confirm that the cuff is wrapped correctly (refer
to pages 14 and 15).
• Confirm that the cuff is wrapped correctly (refer
to pages 14 and 15).
• Ask the patient not to move during the measure-
ment.
• Check the patient for arrhythmia.
