Important Notes on Taking a Measurement
In order to obtain a good heart rate reading, it is important that measurements are taken correctly.
Before taking a measurement for the first time, read these instructions carefully and make sure you
observe the following tips each time you take a measurement.
Make sure that the electrodes are directly touching your skin.
If your hands or skin are dry, wipe them with a damp towel so that they are slightly moist.
If the electrodes are dirty, wipe any dirt off with a soft cloth moistened with disinfectant alcohol or a
cotton swab.
----- Take care not to use too much disinfectant alcohol when cleaning the electrodes.
----- Do not spray or apply disinfectant alcohol on parts other than the electrodes.
Do not move during measurement.
----- Movement, including talking, coughing, or sneezing, during measurement may affect the
measurement results.
If the position of your finger or arm is inappropriate during measurement, the results may be
unreliable, so make sure to check their position before taking a measurement.
Heart Observer Instruction Manual
12
After taking a measurement, disinfect the electrodes by wiping them with a soft cloth or cotton swab
moistened with disinfectant alcohol. If you do not disinfect the electrodes there is a risk of skin
disease.
Measurement methods
Preparation
Make sure that you are in relaxed position. And user can take a measurement as the following
methods. Prepare your pose and then press the START button to start a measurement. The
measuring mode is depended on your setting in“ECG measure”menu. Refer to“Measurement
Mode settings”.
NoteThe ideal posture is one where you are seated comfortably with your back straight. You can also
take a measurement while you are standing or while lying down.
Palm-palm measurement
Make sure that hold the metal electrode 3 of the unit with the right
thumb and the electrode 1 with the right index fingerthen hold the
electrode 9 with left thumb and the electrode 10 with the left index
finger, refer to Picture 4-1.
Palm-chest measurement:
Picture 4-1
Heart Observer Instruction Manual
13
If palm measurement is not ideal, please adopt palm-chest measurement. Hold the unit with right hand;
make sure that the index finger touch metal electrode 1 and right thumb touch metal electrode 3
comfortably and closely. Place the electrode 10 against left chest on bare skin about 5 cm bellow your
left nipple. (Refer to picture 4-2 )
Picture 4-2
Note: If you have any problems applying the unit when measuring in palm-chest mode, please ask
your doctor for advice.
Improper Operation Methods:
A. The touch point of the right hand does not contact well with the unit.
B. The handheld gesture is NOT correct.
Heart Observer Instruction Manual
14
C. The electrode 10 does not contact fully the skin.(E.g. with clothes on body while taking
measurements).
Measurement for Female
Locate the unit at the lower end of breastbone and move horizontally
to the middle of the left part of the chest. If necessary, gently lift the breast
and place the “10” electrode under the left breast. Unless the electrode
comes in contact with the brassiere, it is NOT necessary to remove it;
if you have any problem, please consult your doctor.
Important: The small open circle indicates the proper position of electrodes, as shown in Picture 4-3.
Notes:
Make sure that you are relaxed and that your chest is free of tension.
Press the electrode 10 to make it closely against your bare chest. Do not place the electrode
on clothing as this will result in an inaccurate measurement.
If measuring in dry circumstance, which might cause weak heart pulse signal, please wet
your skin or hands with some diluted salt water or clean water. This would strengthen the
Picture 4-3
Heart Observer Instruction Manual
15
heart pulse signals, and make the analysis much more accurate.
When taking an palm-chest measurement, if you have problems applying the unit so that the
metal electrodes 10 is flat against your chest, please ask your doctor for advice.
Measurement Mode settings

interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-- Consult the dealer or an experienced radio/TV technician for help

General information about the Heart Rate Measurements
The heart is a muscular pump controlled by electrical impulses generated by the body. It is divided
into two by the septa and each side has two chambers –an atrium and a ventricle-linked by a
one-way valve. The left atrium and ventricle control oxygenated blood, and the right atrium and
ventricle control de-oxygenated (“used”) blood.
The electrical impulse that causes the heart to beat spreads across the atria, causing the left and
right atrium to contract and pump blood into the left and right ventricles respectively. The tow
ventricles then contract and pump blood out of the heart. The heart muscle then relaxes, or
re-polarises, allowing blood to fill up the heart again.

An Heart Observer is able to measure the electrical impulse as it passes across and through the
heart, causing the heart to beat. An ECG does not measure the movement of your heartbeat, but
rather the electrical activity that causes the heart to beat. The measurements recorded by an Heart
Observer, when combined with a medical examination, can help your doctor monitor your heart
condition. The ECG measurements recorded by the unit are NOT designed or intended for medical
diagnosis. Conditions such as arrhythmia and Ischemia can only be diagnosed by a doctor through
a special examination.
About the ECG
The ECG waveform shows the rhythm of your heartbeat during the 30-second measurement and
displays the electrical activity causing the heart to beat. The waveform for each heartbeat shows
the progress of the electrical impulse across and through the heart.

The first peak indicates the spread of the impulse over the atria and the beginning of their
contraction. This is known as the P wave. The second peak indicates the spread of impulse over
the ventricles and the beginning of their contraction. This is known as the QRS complex. The third
peak indicates the activity as the heart relaxes (re-polarization), and is known as the T wave.
What is Arrhythmia?
Arrhythmia is a condition where the heartbeat rhythm is abnormal due to flaws in the bio-electrical
system that drives the heartbeat. Typical symptoms are skipped heartbeats, premature contraction,
an abnormally rapid (tachycardia) or slow (bradycardia) pulse. This can be caused by heart disease,
ageing, physical predisposition, stress, lack of sleep, fatigue etc. Arrhythmia can only be diagnosed
by a doctor through a special examination.
What is Ischemia?
Ischemia is a condition in which insufficient oxygen is supplied to parts of the heart or other parts of
the body. This is usually due to a blockage or partial blockage of an artery.
Ischemia can only be diagnosed by a doctor through a special examination.
