How Ub-328 Works; Before You Start - LifeSource UB-328 Instruction Manual

LifeSource blood pressure monitors are easy to use, accurate and digitally display
®
full measurement readouts. Our technology is based on the "oscillometric
method" – a noninvasive blood pressure determination. The term "oscillation"
refers to any measure of vibrations caused by the arterial pulse. Our monitor
examines the pulsatile pressure generated by the arterial wall as it expands and
contracts against the cuff with each heartbeat.
The cuff is inflated until the artery is fully blocked. The inflation speed is
maximized and the pressure level is optimized by the device. The monitor takes
measurements while the cuff is both inflating and deflating. This results in a faster
measurement providing greater comfort to the user.
The UB-328 provides accurate readings on wrists with a circumference between
5.3 and 7.7" (13.5 and 19.5 cm).
The unit requires two "AAA" (1.5 volt) batteries to operate (alkaline batteries
recommended). To install batteries (or to replace when "Low Battery" symbol
appears), proceed as follows:
Slide the battery cover as shown to remove
from the device
Insert batteries into designated areas ensuring
a correct match with positive (+) and negative
(-) terminals.
Return battery cover by sliding back on to
monitoring device.
