Please refer to the following steps at the time of connecting chest
electrodes:
1. Check whether the electrodes are clean and intact;
2. Clear up lead wire to avoid twisting, and firmly connect the electrode
connector to electrodes;
3. Wipe up with alcohol the skin where electrodes will be placed;
4. Evenly spread the conductive paste in a diameter of about 25mm at each
position on chest where electrodes will be placed;
5. Evenly spread a thin layer of conductive paste at the edges of chest
electrode suction balls;
6. Place the electrodes on skin and squeeze the rubber balls, and then loosen
the rubber balls, so the electrodes will be adsorbed on the corresponding
positions on chest.
Emplacing of electrodes on limbs
Limb electrodes shall be placed at the positions with close contact with skin
such as upper side of wrist and upper inner side of ankle. Please refer to the
following steps at the time of connecting limb electrodes:
1. Check whether the electrodes are clean and intact;
2. Clear up lead wire to avoid twisting, and firmly connect the electrode
connector to electrodes;
3. Wipe up with alcohol the skin where electrodes will be placed;
4. Evenly spread the conductive paste on skin;
5. Evenly spread a thin layer of conductive paste on the surface of limb
electrodes;
6. Properly place the electrodes on skin.
Caution:
The conductive paste shall not be used excessively and the spreading
layers shall be separated; otherwise, electrode short-circuit will be
caused, resulting in ECG signal record error.
Patients and the machine can be connected via lead and electrode
only.
If ECG waveform does not appear during long period, please confirm
whether electrodes are in good contact with skin.
