Solution
• Check that the probe is properly
attached to the patient.
T h e
• Be sure that the light-source and
sensor sections are properly lined
up.
• If the part being measured is thick,
insufficient light will be transmitted.
Attach probe to a thinner part.
• Clean the light-source and sensor
sections.
• Take measures to prevent direct
entry of strong light to the probe.
• If this message reappears even
though the above points have been
c h e c k e d , t h e p r o b e m a y b e
malfunctioning. Use another probe.
• Check that the probe is properly
attached to the patient. If the probe
i s p r o p e r l y a t t a c h e d b u t t h i s
message still appears, the circulation
in the area being measured may not
be good. Move the probe to an area
from which a sufficiently strong pulse
signal can be received.
• If a sufficiently strong pulse signal
cannot be obtained regardless of the
area to which the probe is attached,
the probe may be malfunctioning.
Use another probe.
• A t t a c h t h e p r o b e t o t h e b o d y
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, search for a
location where adequate pulse
signals can be obtained. Attach the
p r o b e a g a i n o r w a r m u p t h e
measurement location.
• In particular, when the pulse is weak,
t h i s e r r o r t e n d s t o o c c u r . F o r
improved measurement accuracy, if
the probe 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.
