The Measure-
ment Value and
Cause
• Insufficient light for
measurement.
• Strong light enters the
finger holder's sensor
directory.
• Pulse signal required
for measurement is
not being received.
• T h e p u l s e i s w e a k
and the pulse signals
required for the meas-
urement are not ob-
tained. The measure-
ment value is dis-
played, however, the
a c c u r a c y o f t h e
measurement values
c a n n o t b e g u a r a n -
teed. Thus, the meas-
ured value must be
considered as guid-
ance only.
• Motion artifact
• The pulse rate ex-
ceeds the upper limit
( 2 5 0 b p m ) o f t h e
measurement range.
Solution
• Check that the finger holder is properly
attached to the patient.
• Clean the light-source and sensor sec-
tions.
• Take measures to prevent direct entry
of strong light to the finger holder.
• Check that the finger holder is properly
attached to the patient. If the finger
holder is properly attached but this
message still appears, the circulation
in the area being measured may not
be good. If this occurs, warm up the
measurement location.
• Attach the finger holder to the body
correctly. If this message is displayed
when the unit is attached to the patient
correctly, the measurement conditions
are regarded as blood circulation or
other circulatory problems. If this
occurs, warm up the measurement lo-
cation.
• In particular, when the pulse is weak,
this error tends to occur. For improved
measurement accuracy, if the finger
holder is exposed to strong light, wrap
it with a piece of black cloth, etc. Also
make sure that the patient rests calmly
to avoid influence of body movement.
• Attach the finger holder to the patient
properly. If this message still reappears
even though the finger holder is attached
properly, keep the measuring point as
stationary as possible.
• Measurement cannot be performed
when the upper limit of the measure-
ment range is exceeded.
