HOW UB-511 WORKS
?
BEFORE YOU START
LifeSource™ Blood Pressure Monitors are easy to use, accurate
and display clear digital measurements. Our technology is based
on the “oscillometric method”. The term “oscillation” refers to the
measure of vibrations caused by the arterial pulse and is a non-
invasive method to determine blood pressure.
Our monitors examine the pulsatile pressure generated by the
arterial wall as it expands and contracts with each heartbeat
against the monitor’s cuff. This monitor measures your blood
pressure while the cuff is inflating.
The UB-511 provides accurate readings on wrists with a circumfer-
ence between 5.3" and 8.5" (13.5 cm and 21.5 cm).
The unit requires two “AAA” (1.5 volt) batteries to operate. To
install batteries (or to replace when “Low Battery” symbol
appears), proceed as follows:
1. Slide the battery cover as shown to remove
from the device.
2. Insert batteries into designated areas
ensuring a correct match with positive (+)
and negative (-) terminals.
3. Return battery cover by sliding back on to
monitoring device.
Tips for Blood Pressure Monitoring:
☞
Relax for 5 to 10 minutes prior to measurement
☞
Remove watch, jewelry or tight-fitting garments
☞
Use left wrist unless otherwise recommended by physician
Now you are ready to follow these simple steps:
1 . Sit comfortably in a chair near a flat surface.
2. With palm facing upward, attach monitor to
left wrist and fasten securely. The top edge of
the cuff should align with the crease of your
wrist.
3. Position your wrist so it is level with your
heart, using an arm rest if needed.
Positioning of the wrist at heart level is
critical for accurate measurement.
4. Press the START button. The average readings from blood
pressure measurements stored in memory will appear for a few
seconds and the number of measurements stored in memory
will flash two times (e.g. A04). The cuff will then begin to
inflate. It is normal for the cuff to feel very tight.
NOTE: To stop inflation at any time, press START
5. Remain still and refrain from talking or moving during reading.
