<br />how to use bind wrist band
<br />1. plug in the air tube - plug the air tube to the bottom
<br />2. the volume tied to the arm cuff - roll and bind the wrist band on your bare arm. export trachea should hand align the palm of the little finger. (it can be measured both right and left hand, but the results
<br />have different extent of difference. please measure by the same side of arm each time)
<br />3. roll wrist band tightly - don't roll in clothes or it affects the accuracy of measurement. don't roll too tight, can place one finger. (most appropiater) fasten the hasp.
<br />how to use measure manual
<br />1. place elbow on the desk.
<br />2. the wrist band and heart on the same level.
<br />3. palm and relax.
<br />measure at the same time with he same arm and same gesture each .
<br />position of the wrist band will cause the result to change.
<br />you'd better measure your basic blood pressure, (pressure of wake up and do not want emiction in the morning) if you cannot, please take before marl or sports.
<br /> 
<br />do not touch instrument, wrist band and air tube.
<br />be quiet and relaxed during measurement. 
<br />be quiet for at least 5 mins before measuring.
<br /> relax body, arm and fingers, no muscle activity. 
<br />do not speak during measuring, be quiet. 
<br />measure again 4 to 5 min mins if you need to measure in succession.
