Introduction
Thank you for purchasing the Welby® Upper Arm Blood Pressure Monitor. This fully
automatic device measures blood pressure and pulse rate and detects an irregular
heart beat (arrhythmia) fast and easily and then displays the results on the LCD screen.
It works using the oscillometric method of blood pressure measurement. This means
the monitor detects your blood’s movement through your brachial artery and converts
the movements into a digital reading. An oscillometric monitor does not need a
stethoscope so the monitor is simple to use by oneself.
Please read this manual thoroughly before use and save it for future reference.
PQVG
We highly recommend that you consult with your physician or licensed
healthcare professional if you have any questions about your blood pressure
either before or as a result of using this monitor.
Please also save your original receipt as proof of purchase. It may be
required to validate your warranty in case you need service for this device.

Safe handling of batteries
Batteries may contain combustible materials. If not handled correctly, batteries can
leak, become very hot, ignite or even explode, which could damage your device and/or
cause injuries. It is very important that you follow the instructions below:
• Keep batteries away from children. If batteries are mistakenly swallowed, call
poison control or 911 immediately.
• Before inserting the batteries, check that the contacts in the device and on the
batteries are clean and, if necessary, clean them.
• Never charge batteries (unless it is expressly specified). Risk of explosion!
• Never short-circuit the batteries.
• Do not dismantle or deform the batteries. You could injure your hands or fingers or
battery fluid could come into contact with your eyes or skin. If this happens, rinse
the affected areas immediately with a large amount of clean water and contact
your physician immediately.
• Never expose the batteries to excessive heat (such as direct sunlight, fire or similar).
• Always observe the correct polarity. Make sure that the plus (+) and minus (-) poles
are correctly inserted to avoid short circuits.
• Remove discharged batteries from the device immediately.

• Remove the batteries from the device if you do not intend to use it for an extended
period.
• Replace all of the old batteries in a device with new batteries of the same type.
Service & Repairs
Please contact the Customer Care line if you have questions about the device or
experience technical problems.
Never try to open or repair the device yourself. There are no user serviceable parts
inside and it will void your warranty.

Frequently Asked Questions
What is blood pressure?
Blood pressure is the force exerted by blood against the walls of the arteries as blood
is pumped through the circulatory system and is measured in millimeters of mercury
(mmHg). The higher the pressure, the harder the heart has to work to supply blood to
the vital organs in the body.
What are systolic and diastolic values?
With every heartbeat, blood pressure uctuates between a maximum value (systolic),
when the heart contracts and pumps blood into the circulatory system, and a
minimum value when the heart expands and lls up with blood again (diastolic).
What is High Blood Pressure and how is it controlled?
High Blood Pressure, also called by its medical term Hypertension, is an abnormally
high arterial blood pressure. If left unattended, it can cause many health problems
including stroke and heart attack.
Blood pressure can be higher than usual if parts of the circulatory system are restricted,
12450 USA final Content REV1.indd 1212450 USA final Content REV1.indd 12 18.10.2012 12:00:1018.10.2012 12:00:10
13
diseased or abnormal in other ways High Blood Pressure can be controlled by altering
one’s lifestyle, avoiding stress, and with medication under a physician’s supervision. To
prevent hypertension or to keep it under control:
• Do not smoke
• Exercise regularly
• Reduce salt and fat intake
• Have regular physical checkups
• Maintain proper weight

Measuring blood pressure
Everybody’s blood pressure changes constantly. Fluctuations may be caused by mental
and physical factors (such as diet, exertion, smoking, caffeine or stress). Blood pressure
can also be affected by the time of day, time of year or temperature.
This blood pressure measuring device helps you to take regular, comparative
measurements. Individual, irregular measurements are therefore not very meaningful.
The guidelines for normal and high blood pressure (diastolic and systolic value) have
been defined by the World Health Organization (WHO) as shown in the following table.
12450 USA final Content REV1.indd 1512450 USA final Content REV1.indd 15 18.10.2012 12:00:1118.10.2012 12:00:11

Before taking your blood pressure measurement
Using this device, you can get an overview of your blood pressure by measuring it
regularly and keeping clear records.
To make sure that the values give a realistic picture of your blood pressure, please
follow the instructions below:
• Measure your blood pressure several times during the day.
• Always measure your blood pressure at the same time of day.
• Always take blood pressure measurements under the same conditions. Always use
the same arm.
• Measure your pressure when you are relaxed. Try to rest for fifteen minutes before
measuring your blood pressure.
• You should wait an hour after a large meal before measuring your blood pressure.
• Do not smoke or drink alcohol before measuring your blood pressure.
• Do not exercise for at least 60 minutes before measuring your blood pressure.
• Do not measure your blood pressure if you are under stress or are tense.
• Measure your blood pressure at normal body temperature, but not if you are too
hot or cold.
• Wait approximately five minutes before repeating the measurement.

If you record a value that differs greatly from your normal blood pressure
measurement, you should take another measurement around five minutes later. This
will allow you to rule out any of the factors mentioned above, which could result in an
incorrect measurement.
About your measurement results
CAUTION!
If the measurements obtained give you cause to be concerned about your health,
consult with your physician or licensed health care professional. Do not change
your current treatments and/or dosages of medication(s) as a result of your
measurements unless you have discussed this first with your physician.
By using your device regularly and recording your results, you can get a clear overview
of your blood pressure. Everybody’s blood pressure changes constantly. Fluctuations
may be caused by mental and physical factors such as diet, stress, exertion, smoking
and caffeine. Blood pressure can also be affected by the time of day, time of year and
temperature. In addition, arrhythmia (irregular heartbeat) can lead to imprecise results.
In this case, discuss with your physician whether you should be using this device.

How does the blood pressure monitor work
Your blood measuring monitor contains high quality technical components and
materials for measuring and to show the results on the display. It also measures and
displays your pulse rate.
The blood pressure monitor measures blood pressure indirectly using a cuff around
the upper arm. Inflating the cuff presses the arteries together so that no more blood
can flow through them. If the pressure in the cuff is then reduced, this creates a relation
between the cuff pressure and the blood pressure.
The monitor has electronic step valves that can detect even slight changes during the
measurement, which can be evened out using the cuff pressure.
By reducing the pressure step-by-step, fluctuations in the cuff are recorded by the
monitor and included in the assessment. If no fluctuations are recorded for a step, the
air pressure is reduced. Existing fluctuations are assessed at the corresponding step
level until they can be determined precisely.
