ERROR CODE POSSIBLE CAUSE CORRECTION
E07 Manual stop The measurement was manually
interrupted by depression of the red
Start/Stop button.
E08 Korotkoff sounds are
undetectable. Check that the lower microphone is
affixed with the sensing side (skin side)
facing the patient’s arm.
Note: The microphone should always
be taped to the arm with the supplied
affixing tape. Place "X" of tape over the
top of the microphone.
E11 More than 256 Korotkoff sounds
are measured. Check for a break in the microphone
lead. Check for external damage to the
microphone. Microphone circuit may be
damaged.
Note: If a break in the microphone lead
or external damage has occurred, the
microphone assembly must be
replaced.
E20 Pulse Error
Pulse less than 35 beats or more
than 200 beats per minute. Check the position of the lower
microphone and then re-correlate it to
the subject.
Note: Certain physiological conditions
or pharmaceutical treatment may
excessively reduce or increase a pulse
rate. In cases of excessively low pulse
rates, have the subject walk or stand a
few minutes to raise the pulse rate
above 35 beats per minute.
E21 Diastolic greater than 160 mmHg
or less than 40 mmHg. Outside of normal physiological
parameters.
E22 Systolic greater than 280 mmHg
or less than 60 mmHg. Outside of normal physiological
parameters.
E23 Difference between systolic blood
pressure and diastolic blood
pressure less than 10 mmHg. Outside of normal physiological
parameters.
E24 Difference between systolic blood
pressure and diastolic blood
pressure greater than 150
mmHg. Confirm that the subject is not moving
during measurement. Reposition the
lower microphone and then correlate it
to the subject.
Note: If a measurement error occurs (other than E08) when the “Auto” mode is set, the
monitor will automatically take a 2nd measurement. If a second measurement
error occurs, a 3rd measurement will not be taken. The monitor will return to its
programmed interval.
