• The waveform isnormalized.Please
read
the measured value
whenthewaveform on screen is equably andsteady1Joing, here
this measured value is optimal value,and the waveform atthe
momentisthe standard one.
• Ifsomeabnormal conditions appear on the screen while using,
pull outthefingerand reinsert to restore normal
use.

INDICATION
FOR
USE:
For usewith sporting and aviation activities, and
to
monitor heart
rate during exercise.
OVERVIEW
The
pulseoxygen saturation is the percentageof
Hb0
2 inthetotal Hb
in
the blood,so-called the 02 concentration in the blood. Itis an im-
portant bio-parameterforthe respiration. Forthe purposeofmeasuring
the
Sp0
2 more easily and accurately,ourcompany developed the
Pulse
Oximeter.Atthesame time,the device can measurethe pulse
rate
simultaneously.
The Pulse Oximeterfeatures
in
small volume, lowpowerconsumption,
convenientoperation and being portable. It is only necessaryforuser
toputone ofhisfingers intoafingertip photoelectric sensorfor mea-
surement, andthe displayscreen will directly show measured value of
Hemoglobin Saturation.
FEATURES:
• Operationofthe productis simple and convenient.
• The productis small
in
volume, light
in
weightand convenient
tocarry.
• Powerconsumption ofthe product is lowand the2 originally
equippedAAAbatteries can be operated continuouslyfor 20 hours.
• The productwill enter standby modewhen no signal is inthe
productwithin 5 seconds.
• Display direction changes automaticallyforeasy viewing.
MAJOR
APPLICATIONS
AND SCOPE OF
APPLICATION
The
Pulse Oximetercan beused
in
measuring pulseoxygen saturation
and pulse
rate
through the
finger.
The productis suitable forfamily use
(It
can beused before or afterdoing sports, and itis notrecommended
tousethedevice during the process ofdoing sports).
A The problem ofoverrating would emergewhen the user
is
Lil
suffering from toxicosis which
is
caused bycarbon monoxide,
the

PRINCIPLE
AND
CAUTION
Principle
of
Measurement
Principleofthe Oximeteris asfollows:
An
experienceformula ofdata
process is establishedtaking use ofLambert Beer
Law
according to
Spectrum Absorption Characteristics ofReductive Hemoglobin
(Hb)
and Oxyhemoglobin
(HbO
2)
in
glow& near-infrared zones. Operation
principle ofthe instrument
is:
Photoelectric Oxyhemoglobin Inspection
Technology isadopted
in
accordancewith Capacity Pulse Scanning
& Recording
Technology,
sothattwo beams ofdifferentwavelength of
lights can befocused onto human nail tipthrough perspective clamp
finger-type
sensor.
Then measured signal can beobtained bya pho•
tosensitive element, information acquired through which
will
