How to Measure Blood Pressure Correctly
How to Wrap the Wrist Cuff
Wrap the cuff snugly on your wrist.
• This monitor is preset to measure on your left hand when you purchased
it. If you desire to measure on your right hand, change the mode to
Right Hand measurement in setting. (Refer to Page 18.)
• Wrap the wrist cuff over your skin.
• Please be careful not to catch the cuff of your shirt.
1. Place the wrist cuff over your left wrist with your left thumb
facing upward.
• Leave approx 10-15 mm between the cuff and the bottom of the palm of
your hand as shown in the figures.
2. Pull the wrist cuff upward and close the cuff firmly with the
velcro tape as shown.
Lightly press the Velcro tape with your finger so that it is fastened tightly.
• If the Velcro tape is not tightly fastened, the wrist cuff will become loose
during measurement and the measurement may be impossible.
• People with a slender wrist (wrist circumference of less than 145 mm)
may feel loose because the wrist cuff may not be wrapped snugly. In
that case, do not force to wrap the wrist cuff. It will not affect the
measurement.
• Fold and fasten the extra portion of wrist cuff as shown to the right.
• Even if the extra portion of wrist cuff is not fastened, it will not affect the
measurement.
3. To take measurement on your right wrist
You can measure your blood pressure on your right wrist too. Wrap the
wrist cuff as shown in the Figure to the right.
• Change the Measurement to Right Hand in the Setting Mode. (Refer to
Page 18.)

Breathe deeply for five to six times before
measurement, and then return to natural
respiration. Relax yourself by relieving
stresses from your shoulders and arms.
When measuring, lift the wrist cuff to the level
of your heart (level of nipple).

be displayed higher especially when making a
firm grip.
Do not support the
wrist cuff with
another hand. It may
cause erroneous
measurement
results.
