•
Integrity of the patient cable, including the main cable and lead wires, should be checked
regularly. Make sure that it is conductible;
•
Arrange the patient cable to avoid twisting, knotting or crooking in a closed angle while
using it;
•
Do not drag or twist the patient cable with excessive strength while using it. Hold the
connector plug instead of the cable when connecting or disconnecting the patient cable;
•
Store the lead wires in a big wheel or hang it to avoid twisting;
•
Once damage or aging of the patient cable is found, replace it with a new one immediately.
7.4.3.3 Electrodes
•
Electrodes must be cleansed after use and make sure there is no remainder gel on them;
•
Keep suction bulbs of chest electrodes away from sunshine and excessive temperature;
•
After long-term use, the surfaces of electrodes will be oxidized because of erosion and
other causes. By this time, electrodes should be replaced to achieve high-quality ECG
records.
8. Troubleshooting
8.1 ECG Waveform of Some Leads Cannot Be Displayed
•
After the electrodes are connected to the patient, the ECG waveform is not stable and
baseline drifts. The software is saturated or overflows when running.
•
The equipment, patient cable and patient are not securely connected.
•
The patient cable is faulty. Check the patient cable according to the method described
in 4.3. If the problem still exists, please contact our after-sales service department or the
designated repair unit.
•
The signal channel of the equipment has malfunction. Please contact our after-sales service
department or the designated repair unit.
8.2 Keypad Not Work
•
Generally, it is resulted from the loose connector between the control panel and the
circuit board. Please ask the professional maintenance personnel to open the cover of the
equipment and reconnect the connector. If the problem still exists, please contact our after-
sales service department or designated repair unit.
8.3 AC Interference
•
In the ECG recording process, there is a certain range of regular interference. There is
obvious ECG baseline jitter, as shown in the following ECG waveform.
