Measurements
Model UA-621 is designed to detect the pulse and to inflate the cuff to a systolic
pressure level automatically.
If your systolic pressure is expected to exceed 230 mmHg, read
"Measurement With The Desired Systolic Pressure" on the next page.
Normal Measurement
1. Place the cuff on the arm (preferably the left arm).
Sit quietly during measurement.
2. Press the
START
button.
The average blood pressures and last data
number are displayed briefly.
Then the display changes, as indicated in the
figure at the right, as the measurement
begins. The cuff starts to inflate. It is normal
for the cuff to feel very tight. A pressure bar
indicator is displayed, as in the figure at the
right, during inflation.
Note: If you wish to stop inflation at any time,
press the
START
button again.
3. When inflation is complete, deflation starts
automatically and the
(heart mark) blinks,
indicating that the measurement is in
progress. Once the pulse is detected, the
mark blinks with each pulse beat.
Note: If an appropriate pressure is not obtained,
the device starts to inflate again
automatically.
4. When the measurement is complete, the
systolic and diastolic pressure readings and
pulse rate are displayed. The cuff exhausts
the remaining air and deflates completely.
5. Press the
START
button again to turn off
the power.
Note: Model UA-621 is provided with an automatic
power shut-off function. Allow at least three
minutes between measurements on the same
person.
