A3 Measurements
This instrument measures with the forefinger inserted in the finger cuff. To ensure
stable measurement, hold the instrument properly by placing your thumb on the
thumb rest. Most important is to hold the instrument body securely and to not
place your thumb on the bottom of the instrument (which would apply a force to
the forefinger).
1. Open the finger holder.
2. Insert the index finger and release the finger holder.
• Opening the finger holder will start measurement automatically.
Notes on Measurements
• Remove nail polish before taking measurements.
• If no measurement values are displayed, attach the finger holder to a thinner
finger to take measurements.
• It may not be possible to take measurements in case of blood circulation or
blood
stream problems. In this case, remove the finger holder, rub or warm
the finger to improve blood circulation, then re-attach the finger holder.
• Do not use the instrument in areas where it is exposed to strong light such as
direct sunlight.
• Check that the pulse level meter changes in synchronization with the pulse
rate during measurements. In the following cases, the level meter may not
operate properly, hindering display of correct values.
• Rapid body movement
• Finger Holder is not attached to the patient properly.

light.
