2.5 Sitting Correctly
To take a measurement, you need to be relaxed 
and comfortably seated in a room with a 
comfortable temperature. Place your elbow on 
the table to support your arm.
• Sit in a chair with your legs uncrossed and your 
feet flat on the floor.
• Sit with your back and arm being supported.
• The distance from the top of your seat 
measuring to the top of the table you are sitting 
at, should be 12 plus or minus 2 inches (30 ± 5 
cm). If the distance measured between the top 
of your seat and table do not fall within this 
parameter, correct your seat or table height.
If you are unable to make any seat or table 
adjustments, please turn off the heart zone indicator and position your wrist at 
heart level by yourself. Refer to section 6.1.
• Your monitor must be approximately the same level as your heart. If the monitor is 
too high above your heart, your blood pressure will be artificially low. If the monitor 
is too low below your heart, your blood pressure will be artificially high.
• Relax your wrist and hand. Do not bend your wrist back, clench your fist, or bend 
your wrist forward.
