Disposable Electrode Connection
1) Align all lead wires of the patient cable to avoid twisting, and connect the alligator clips to
the lead wires.
2) Clean the electrode areas on the body surface with 75% alcohol.
3) Attach the disposable electrodes to the electrode positions on the body surface.
4) Clip the disposable electrodes with the alligator clips.
The quality of ECG waveform will be affected by the contact resistance between the patient and
the electrode. In order to get a high-quality ECG, the skin-electrode resistance must be minimized
while connecting electrodes.
WARNING
1. Make sure that all electrodes are connected to the patient correctly before operation.
2. Ensure that the conductive parts of electrodes and associated connectors, including
neutral electrodes, do not come in contact with earth or any other conducting objects.
4.6 Inspection before Power-On
In order to avoid safety hazards and get good ECG records, the following inspection procedure is
recommended before power-on and operation.
1) Environment:
♦ Make sure that there is no electromagnetic interference source around the equipment,
especially large medical electrical equipment such as electrosurgical equipment,
radiological equipment, magnetic resonance imaging equipment etc. Turn off these
devices when necessary.
♦ Keep the examination room warm to avoid muscle tremor voltages in ECG signals
caused by cold.
2) Power Supply:
♦ If the mains supply is used, please check whether the power cord is connected to the
unit well. The grounded three-slot outlet should be used.
♦ When the battery capacity is low, recharge the battery before use.
