Instructions for Operation
• The nger should be put in properly and correctly.
• Do not shake the nger. Keep at ease during measurement.
• Do not put wet nger directly into sensor.
• Avoid placing the device on the same limb which is wrapped with a cuff
for blood pressure measurement or during venous infusion.
• Do not let anything block the emitting light from device.
• Vigorous exercise and electrosurgical device interference may affect
the measuring accuracy.
• The orientation-sensor works on the basis of the gravity. A small movable
metal ball is built in the orientation-sensor for detecting the orientation
of the oximeter. When you want to change the oximeter’s display direction,
if you move the oximeter too slowly, the movable metal ball will also move
slowly because of not enough acceleration. Consequently the response
of orientation detection would be delayed. Please move the oximeter with
a bit of force if you want to change the display direction (such as bend/ex-
tend your nger quickly), so an acceleration is provided to the
orientation-sensor for quick sensing the orientation change.
• Using enamel or other makeup on the nail may affect the accuracy
of measurement, too long ngernail may casue failure of measurement
or unaccuracy measurement result.
• Keep the oximeter away from dust, vibration, corrosive substances,
explosive materials, high temperature and moisture.
• Existence of high intensive light sources, such as uorescence light,
ruby lamb, infrared heater or strong sunshire, etc. may cause unaccuracy
of measurement result. Please put an opaque cover on the sensor
or change the measuring site.
• If the rst reading appears with poor waveform (irregular or not smooth),
then the reading is unlikely true, the more stable value is expected
by waiting for a while, or a restart is needed when necessary.
Note: Due to the working principle of orientation sensor used in oximeter,
there is a small metal ball which is movable within its compartment
of the orientation-sensor. Therefore you can hear a slight “clatter” sound
when you wave or shake the oximeter. It is normal and not caused
by unwanted part.
