Chapter 9 Troubleshooting

Note:

To troubleshoot this machine in the service, follow the instructions below to eliminate the problem first.

If the attempt fails, refer to the dealer in your local area or the manufacturer. The service should be

performed by a professional electrician. Do not open the machine by yourself.

9.1 No Display on the Screen

1. Shut down the machine and unplug the power. Use a universal multi-meter to check if the outlet has

proper voltage, if the power cable is in good condition, and if the power cable is properly connected with

this apparatus or the outlet? Remove the fuse from the back cover of this machine, and make sure it is in

good condition.

2. If the trouble still exists, loosen the screws fastening the top cover of the machine and open the top cover.

Check if the signal plug of the monitor is properly connected with the Type D jack on the right side of the

display card

9.2 Excessive ECG Signal Interference or Thick Baseline

1. Check if the plate electrodes are properly located, and if valid plate electrodes are used.

2. Are the lead wires properly inserted? If no ECG curve is displayed, check if the ECG lead wires are

broken.

3. Does the mains outlet have standard grounding wire?

4. Is the exclusive grounding wire of the apparatus properly grounded?

9.3 No Blood Pressure and Pulse Oxygen Measurements

1. Check if the blood pressure cuff is properly wrapped around the arm according to the operating

instructions, if the cuff leaks, and if the inlet is closely connected with the NIBP jack on the front panel?

Check if the indicator of the pulse oxygen probe flashes and if the pulse oxygen probe is properly

connected to the SpO2 jack on the front panel.

2. Loosen the four screws fastening the top cover of this apparatus and check if the multifunctional board

(MID) and electronic disc card (SCPU) nearest to the rear end of the LCD display are properly inserted in

the slots on the main board.

9.4 System Alarm

1. When the parameter value is higher or lower than the alarm limits, the alarm will ring. Please check

whether the alarm limit value is proper or the condition of the patient.

2. Leads off. Please check the connection of the leads.

3. Probe off. Please check the connection of the probes.
