The UB-328 automatically stores up to 30 blood pressure and
pulse measurements in its memory. Measurements stored in mem-
ory are assigned an index number in the order of the newest to the
oldest. The oldest reading displays as "n01".
To retrieve readings, follow these simple steps:
1.
When the display screen is blank, press and release the
Memory button. You will see the average blood pressure read-
ing displayed. Press and release the Memory button again.
You will see the index number of the most recent reading fol-
lowed by the measurement.
2.
If you want to retrieve other measurements in memory, press
and release the Memory button repeatedly until the desired
index number is reached (e.g. n14). The measurement will
then be displayed.
3.
The display will shut off automatically a few seconds after the
readings are displayed.
To clear the measurement history from memory, remove the bat-
teries from the unit and then place the batteries back into the bat-
tery holder.
NOTE: If there are no measurements stored in memory, you will
see two 0s displayed vertically followed by a blinking "A00".
NOTE: Stored measurements will be lost if batteries become low
or are removed.
ABOUT BLOOD PRESSURE
❤
What Is Blood Pressure?
Blood pressure is the force exerted by blood against the walls of
the arteries. Systolic pressure occurs when the heart contracts;
diastolic pressure occurs when the heart expands. Blood pressure
is measured in millimeters of mercury (mmHg).
What Affects Blood Pressure?
Blood pressure is affected by many factors: age, weight, time of day,
activity level, climate, altitude and season. Certain activities can
significantly alter blood pressure. Walking can raise systolic pres-
sure by 12 mmHg and diastolic pressure by 5.5 mmHg. Sleeping
can decrease systolic blood pressure by as much as 10 mmHg.
Taking your blood pressure repeatedly without waiting an interval
of 5 to 10 minutes between readings, or without raising your arm
to allow blood to flow back to the heart, can also affect it.
In addition to these factors, diet beverages containing caffeine or
alcohol, certain medications, emotional stress and even tight-fit-
ting clothes can make a difference in the readings.
What Causes Variations In Blood Pressure?
An individual’s blood pressure varies greatly from day to day and
season to season. In hypersensitive individuals, these variations
are even more pronounced. Normally, blood pressure rises during
work or play and falls to its lowest levels during sleep.
