GENERAL
This instruction manual is intended to assist the user in safe and efficient operation
of the wrist type digital blood pressure monitor (hereinafter: device) model 1143.
The device must be used in accordance with the procedures described in the
manual. It is important to read and understand the entire manual, especially the
section <Tips on taking blood pressure measurement>.
This device is intended for the noninvasive measurement of systolic and diastolic
arterial blood pressure and pulse rate in adults (age 15 and above). Consult your
physician before using this device on children or persons with arrhythmia.
PRINCIPLE OF OPERATION
This device uses oscillometric technology with Fuzzy Algorithm to measure the
arterial blood pressure and pulse rate. The wrist cuff is wrapped around the wrist
and automatically inflated by an air pump. The sensor of the device catches weak
fluctuation of the pressure in the wrist cuff produced by extension and contraction
of the artery of the wrist in response to each heartbeat. The amplitude of the
pressure waves is measured, converted in millimeters of the mercury column, and
is displayed by digital value.

TIPS ON TAKING BLOOD PRESSURE MEASUREMENT
1. It is necessary to know that arterial blood pressure is subjected to sharp
fluctuations. The level of the arterial blood pressure depends on many
factors. Generally arterial blood pressure is lower in the summer and higher
in the winter. Arterial blood pressure changes with atmosphere pressure
and is affected considerably by many factors, e.g. physical loads, emotional
excitability, stress, meals, etc. Medicines, drinking, and smoking can affect
blood pressure. When blood pressure is measured in the hospital, the value is
sometimes higher than when taken at home. This is believed to be associated
with anxiety experienced during the hospital/clinic visit. Blood pressure may
be elevated when taken in low temperatures. If this device was stored at a low
temperature, it is necessary to leave it at room temperature for at least 1 hour,
otherwise the measurement can be inaccurate. Blood pressure varies by age
and from person to person, and it is recommended to record blood pressure
daily; then you can check with your physician to find out what normal blood
pressure is for you.

2. Patients with cardiovascular diseases: Take measurement under doctor’s
instruction.
Under no circumstances should you alter the dosage of any drug pre-
scribed by your doctor!
3. Accurate measurement of blood pressure may be difficult in people with serious
arteriosclerosis, weak pulse, or in patients with irregular heart rates. Please
consult a qualified physician to interpret your blood pressure readings.

4. Keep quiet and relax during measurement. To obtain accurate readings, wait
one hour after a meal or smoking before taking a measurement.
5. Wait at least 5 minutes before taking the next measurement. Atherosclerosis
and diabetes patients require longer intervals (10-15 minutes), since vessel
elasticity may have decreased in these pathologies.

BATTERY INSTALLATION
1. Open the battery cover and install two alkaline
AAA batteries in the battery compartment as
indicated. Check polarity and ensure the batteries
are correctly positioned;
2. Close the battery compartment cover.
•
Replace the batteries when the replacement
indicator appears in the display or when
the unit does not turn on when button ‘O/I’ is pressed;
•
•
Use only alkaline AAA batteries, do not use rechargeable batteries;
Use only same-age, same-type batteries together. Replace all batteries
simultaneously;
•
•
If the device is to be unused for long time, take out the batteries and store in a
dry environment;
Do not leave uncharged batteries in the device.

CORRECT POSTURE FOR MEASUREMENT
Sit down and place your elbow on a table. Ensure
the wrist is at approximately the same level as the
heart, and the forearm is extended naturally, palm
up. Wrap the cuff around the left wrist as shown
in the illustration, and ensure the cuff is attached
to the wrist securely with the display facing the
user. Loosen and roll up sleeves so that the blood
pressure monitor wrist cuff is in direct contact with
the wrist during measurement.

SETTING THE DATE AND TIME
The device has a 12-hour time format. The icon ‘AM’ indicates the time of Ante
Meridiem and the icon ‘PM’ indicates the time of Post Meridiem. To get accurate
date and time, the user should preset the date and time correctly before the first
use of this device.
The operation procedure for presetting Date/Time is as follows:
1. When the device has batteries installed, the display will show as in Fig. 1;
Fig.1
2. Press and hold button ‘M’, then press button ‘O/I’, and the year number will
flash;

3. Press button ‘M’ again to increase the number, and press button ‘O/I’ for
confirmation;
4. When the year setup is confirmed, the month number will flash automatically.
Follow the same instruction as above to set month, day and time;
Fig.3
5. Press button ‘O/I’ to finish setup. If you want to change the date and time,
repeat steps 2, 3, and 4.

TAKING A MEASUREMENT
1. Before taking a measurement, take 3 ~ 5 deep breaths and relax. Do not talk or
move your arm during measurement;
2. Press button ‘O/I’, all symbols will display for 2 seconds as in Fig.4; then ‘0’ will
display. The pump will then begin to inflate while displaying pressure. Generally
the pressure will reach 190 mmHg as in Fig.5;
3. The pump stops inflating and pressure begins to decrease gradually, during
which the user’s blood pressure will display as in Fig.6 (during the deflation
period, remain relaxed and keep your wrist at heart level);
4. The wrist cuff will then deflate quickly and the blood pressure and pulse
measurements will continue to display as in Fig.7;

5. Press button ‘O/I’ to return to standby mode. Wait for at least 5 minutes before
taking another measurement. If the device remains unused for 3 minutes, it will
return to standby mode automatically.
AUTOMATIC INFLATION
This device has 4 levels of inflation pressure: 190 mmHg, 230 mmHg, 270 mmHg
and 300 mmHg. When 190 mmHg is insufficient, or arm movement occurs, the
device will automatically inflate to an appropriate pressure level in order to obtain
the blood pressure measurement.
RAPID DEFLATION DURING MEASUREMENT
If you do not feel well during measurement, or want to stop measurement for any
reason, press button ‘O/I’. The cuff will quickly deflate and the device will switch to
standby mode.

MEMORY FUNCTION
MEMORY RECALL
1. Model 1143 can store 90 sets of readings and will automatically calculate the
average of the last 3 readings. When memory is full (90 sets of readings are
stored), the oldest reading will be replaced by the newest. Memory will not clear
even if the batteries are removed;
2. After a measurement is finished, or when the device is in standby mode, the
user can press button ‘M’ to recall memory. Press button ‘M’ to display the
average value of the last 3 readings as in Fig. 8;

3. Press button ‘M’ again, the device displays ‘01’; then after 1-2 seconds the
latest reading will display as in Fig.9;
Fig.9
4. Press button ‘M’ again, the device displays ‘02’; then after 1-2 seconds the
second-to-the-last reading will display.
DELETING THE MEMORY
To clear memory: After a measurement is finished or when the device is in standby
mode, press and hold button ‘M’ for at least 5 seconds. The device will display ‘Clr’,
which means the stored reading is deleted as in Fig.10.

WHO BLOOD PRESSURE CLASSIFICATION
The World Health Organization (WHO) has established standards for assessment
of high or low blood pressure, regardless of age, as shown in the chart below:
This device has an indicator located on the display which displays a segment,
based on the current data, corresponding to the WHO classification.
For example, if your blood pressure is 140 mmHg (Systolic Pressure), 76 mmHg
(Diastolic Pressure),according to the world health organization standard, your blood
pressure level is Mild Hypertension.
