Model EW3111 is intended to be used for the oscillometric PRECISE
LOGIC™ measurement of systolic and diastolic blood pressure and pulse
rate using a pressurized cuff.
Blood pressure measurements determined with this device are equivalent
to those obtaind by a trained observer using the cuff/stethoscope
auscultation method, within the limits prescribed by the American National
Standard, Electronic or automated sphygmomanometers.
Symptom
The systolic
pressure value or
diastolic pressure
value is high.
The systolic
pressure value or
diastolic pressure
value is low.
The measured
values differ
significantly.
The measured
value differs from
that measured by
the doctor.
The measured
value is different
for each
measurement.
Possible cause
• The cuff was held too low, i.e. not at heart level.
(See page 11)
• The cuff was not attached properly. (See page 10)
• You moved your body or you spoke during
measurement. (See page 11)
• The cuff was held too high, i.e. not at heart level.
(See page 11)
• You moved your body or you spoke during
measurement. (See page 11)
• Your posture was not the same for all
measurements, or measurements were taken
without sufficient time in between. Always wait
approximately 5 minutes before taking another
reading, and above all, relax.
• Blood pressure varies in response to minute
changes in your mental state, such as your reaction
to your doctor taking the measurement. One way to
check this is to bring the unit to your doctor’s office
and directly compare the readings taken by your
physician.
• Relax for at least 5 minutes and then take another
measurement.
If the device still appears to provide unusual or erroneous readings, consult
your physician. If the device does not appear to be functioning properly,
contact Panasonic at 1-800-338-0552.
