Basic Product Information - Nissei WS-1300 Instruction Manual

METHOD OF MEASUREMENT
This product employs the oscillometric method for measurement of
blood pressure and pulse rate. The entire system, including the
cuff, is a single wrist-mounted unit. The cuff is wrapped around the
wrist and automatically pressurized. Circuits within the cuff sense
the small oscillations in pressure against the cuff produced by the
expansion and contraction of the arteries in the wrist in response
to each heart beat. The amplitude of each pressure waves is
measured, converted to millimeters of mercury, and displayed on
the LCD as a digital value. Responding to heart beats, the
electromagnetic deflation control valve maintains the constant
deflation rate irrespective of differences in wrist size. A memory
circuit stores the 60 most recent measurements for comparison.
