MEASUREMENT PRINCIPLE

This product uses the Oscillometric Measuring method to detect blood
pressure. Before every measurement, the unit establishes a "zero pressure"
equivalent to the air pressure. Then it starts inflating the arm cuff, meanwhile,
the unit detects pressure oscillations generated by beat-to-beat pulsatile,
which is used to determine the systolic and diastolic pressure, and also pulse
rate. The device also compares the longest and the shortest time intervals
of detected pulse waves to mean time interval then calculates standard
deviation. The device will display a warning signal with the reading to
indicate the detection of irregular heartbeat when the difference of the
time intervals is over 25%.

OPERATING INSTRUCTIONS - SETTING DATE, TIME, UNIT

It is important to set the clock before using your blood pressure monitor, so that
a time stamp can be assigned to each record that is stored in the memory.
(The setting range of the year: 2014—2054 time format: (12H/24H)

button for 3 seconds to enter the mode for
year setting. Or when the monitor is off, press "S"
button shortly, it will display the time. Then hold
pressing "S" button to enter the mode for year
setting.
