Lead Fault

Lead fault covers the situation that some lead does not give trace in the process of recording that is probably caused by the following.

If you start recording immediately after the patient cable is connected to the patient, the unit will probably face problem of lead fault as a result of saturation or overflow at the baseline adjustment software due to receiving and working on unstable ECG trace & data. In such case, provided good lead connection is guaranteed, you’d better press key “RESET” to rapidly stabilize the trace of each channel or to try another recording, and everything will be OK.

Damaged patient cable may also cause problem of lead fault. See “7.4” for instructions to do checks on the patient cable, and contact our service technicians if it is damaged.

The last reason for lead fault is the unit problem due to failure in signal communication. If you are sure to exclude other cause for this problem, please do not hesitate to contact our service technicians.


Printer Failure

Printer failure covers such circumstance that there will be some vertical break in the printed trace. Whenever a printer fault occurs, you are required to clean the thermal printer with soft cotton with alcohol. If this action does not work, certain thermal emitting component is probably damaged. If printing out trace is blurring, you are required to do as follows:

●Open the paper magazine.
●Adjust the screw located below the printers shown in the following figure.
