4 ECG measurements
There are 2 measuring modes for the ECG measurement, which includes quick measurement by built-in electrodes and long term measurement by
external lead wires.
Quick measurement: press “ ” measure key to enter into the quick measurement directly; it can display single channel ECG signal measured by
built-in electrodes, the signal can be lead I, lead II or chest lead according to the electrode placement. This measurement takes 30 seconds.
Long term measurement: after selecting the signal input option in the measuring option menu, move the cursor to the “ ” measure icon, then press
the “”ok key to start the long term measurement.
For long term measurement, the external lead wires will be used in stead of built-in electrodes; there are two options for signal input.
Limb lead measurement: it measures 3 channels ECG signal for lead I, lead II, and lead III simultaneously and displays them;
Chest lead measurement: it measures single channel ECG signal with different chest lead according to the electrode placement. It is suitable for long
term measurement.
4.1 Methods of ECG measurement
It is recommended to clean your skin with SOAP and water to keep it moist without oily.
1. Measurement by built-in electrodes:
Easy and quick ECG measurement by built-in electrodes can be done by putting electrodes on hand, leg and chest
respectively.
1). Hand measurement
It is convenient to take ECG measurement by hands or palms. The ECG waveform detected by this method is
equivalent to Lead I of regular ECG examination.
A. Palm placement: Hold the device with right hand; make sure that the fingers touch the metal electrode II and III reliably.
Press the electrode I on the left palm, as shown in figure 4-1.
B. Wrist placement: Hold the device with right hand; make sure that the fingers touch the metal electrode II and III
reliably. Press the electrode I below the left wrist about 1 inch, as shown in figure 4-2. When the ECG signal at palm
placement is not good, try to measure with wrist placement.
Figure 4-1 palm placement
Figure 4-2 wrist placement

User Manual for PC-80D Easy ECG Monitor

Note: Keep at ease and make sure the skin contact well with the electrodes during ECG measurement. Please place the device on correct position, do
not shake it during the measurement. Dirty skin may cause poor signal quality, so clean your skin before measuring.
2). Leg Measurement
The ECG waveform detected by Leg Measurement is equivalent to Lead II of regular ECG examination. Keep at ease when
seating down, and then lift your left leg on a bench. Hold the device with the right hand when measuring and make sure that
the fingers touch the metal electrode II and III reliably, place the electrode I on the left leg above the ankle, as shown in
figure 4-3.
Note: Keep at ease and make sure the skin is clean and moist before measuring.
3). Chest Measurement
It is recommended to take ECG measurement on chest, since the signal detected by this way is stronger and with less
interference. The ECG waveform detected by Chest Measurement is similar to the Lead V4 or V5 of regular ECG
examination. Hold the device with the right hand, make sure that the fingers touch the metal electrode II and III
reliably, as shown in figure 4-4, place the electrode I on the left chest align with the midclavicular line (V4 position) or the
anterior axillary line(V5 position) and on the level of the 5th intercostal space.
Note: keep at ease and clean the electrode I by using the wet cloth before measuring. If the waveform baseline wanders or
noisy waveform appears, hold your breath for a moment to get stable and clean signal.
2. Measurement by external lead wires
The ECG signal which is detected by external lead wires is more stable than that by hand measurement. ECG
measurement by external lead wires can be done by placing the electrodes on limbs or chest respectively.
1). Electrodes placement on limbs
On default menu screen enter “ ” option setup menu to select “limb lead” for signal input. By this way, the 3 channels of
limb lead I, II and III can be measured and displayed simultaneously and continuously. Either adhesive electrodes or limb clip
type electrodes (optional) can be used to do the measurement. The location of the electrodes is shown in figure 4-5.
R (red): place on interior of right arm (between the wrist and the elbow);
L (yellow): place on interior of the left arm (between the wrist and the elbow);
F (green): place on interior of the left leg (between the knee and the ankle);
N (black): place on interior of the right leg (between the knee and the ankle)

Operation: Connecting the lead wires after placing the electrodes well and then insert the connector onto the device; Power on the device to select
the “limb lead” for signal input and set the measuring time on option setup menu, then press “”ok key to start the measurement.
Note: keep at ease when seating or lying down. Clean the skin by using the wet cloth when selecting limb clip type electrodes (optional) to measure.
Direction of using disposable ECG electrodes: Tearing off the protective film to place it on the skin, and then connecting the electrodes with lead
wires. It is recommended to put the electrodes on chest for longtime monitoring, please refer appendix 1 for more details.
2). Electrodes placement for Chest Lead Measurement
On default menu screen enter “ ” option setup menu to select “chest lead” for signal input. ECG signal detected by this method is single channel
measurement, which is equivalent to the waveform of regular chest lead. It is intended for professional use (ie. by doctor). The location of the
electrodes is shown in figure 4-6.
R (red): place on interior of right arm (between the wrist and the elbow);
L (yellow): place on interior of the left arm (between the wrist and the elbow);
F (green): on the 5th intercostal space at the left anterior axillary line;
N (black): unused.
Operation: Connecting the lead wires after placing the electrodes well and then insert the connector onto the device; Power
on the device to select the “chest lead “for signal input and to set the measuring time on option
setup menu, then press “”ok key to start the measurement.
Note:
1. The Chest Lead Measurement can obtain the ECG signal of Chest Lead (V1-V6). Please refer to appendix I to select the location of F (green)
electrode when you want to get the different chest lead. At the same time, you should set the lead information (V1-V6) that you want on the option
setup menu.
2. Either adhesive electrode or sucking bulb electrode (optional) can be used to Chest Lead Measurement. Please refer to appendix I for more details
about measuring methods.
