3.2 ECG Measurement
3.2.1 ECG Measuring Method
1 ChestMeasurement
In order to obtain ideal ECG waveform, chest
measurement is suggested firstly. Hold the device with
the right hand. Make sure that the palm and fingers
touch the metal electrode I and II reliably. Place the
electrode III on bare skin about 5cm away below the
left nipple. The ECG signal detected by Chest
Measurement is similar to Lead V ECG signal.
Improper operating method: Figure 3-3A Chest Measurement
A. The contact place of electrode III deviates from left chest.
B. The holding gesture is incorrect.
C. The electrode can not contact bare skin completely. (For example place the electrode
on clothing.)

11
electrode III on the skin 10cm away above the left
foot ankle. The ECG signal detected by Leg
Measurement is equivalent to Lead II ECG signal.
Improperoperating method:
Figure 3-3B
Leg Measurement
A. Wrong holding gesture.
2 LegMeasurement
User Manual for Easy ECG Monitor
If it is not convenient to use chest measurement,
the leg measurement will be recommended. When
measuring, hold the device with the right hand.
Make sure that the palm and fingers touch the
metal electrode I and II reliably. Place the
B. The electrode III can not contact bare skin completely. (For example, place the
electrode III on the sleeve of trousers or socks.)

12
3 PalmMeasurement
User Manual for Easy ECG Monitor
Hold the device with right hand. Make sure that the palm and fingers touch the metal
electrode I and II reliably. Press the electrode III close against the center of the left palm.
The ECG signal detected by Palm Measurement is equivalent to Lead I ECG signal.
Improperoperating method: 3-3C Palm Measurement
A. Waving your both hands at will.
B. Both hands loose contact with electrodes during measurement.
C. Not palm contacts the electrode.
