3.1How to Sit Correctly When Taking a Measurement
You can take a measurement on either your left or right arm.
Note:
•Measurements should be taken in a quiet place and you should be in a relaxed, seated position. Make sure that the room is not too hot or cold.
•Do not take measurement after bathing, drinking alcohol, or exercising.
•Do not move or talk during measurement.
Correct
Posture
Sit upright with your back straight.
Remove tight fitting clothing from your upper arm, and any thick clothing such as a sweater.
Do not place the cuff over thick clothes and do not roll up your sleeve if it is too tight.
Place your arm on a table so 
that the cuff will be at the same 
level as your heart.
The gap between the chair and the top of the table should be between 25cm to 30cm.
