The monitor plays a non-negligible role in the entire monitoring process. Since the monitor works continuously for almost 24 hours, its failure rate is also high. The common faults and troubleshooting methods are introduced as follows:

1. No display when booting

Fault phenomenon: When the instrument is turned on, there is no display on the screen and the indicator light is off; when the external power supply is connected, the battery voltage is low and the alarm is turned off, and then the machine automatically shuts down; useless.

Inspection Method:

① When the instrument is not connected to AC, check whether the 12V voltage is low. This fault alarm indicates that the output voltage detection part of the power board detects a low voltage, which may be caused by a fault in the detection part of the power board or a fault in the output of the power board, or it may be caused by a fault in the back-end load circuit.

②When the battery is installed, this phenomenon indicates that the monitor is working on the battery power supply and the battery power is basically used up, and the AC input is not working normally. The possible reason is: the 220V power socket itself has no power, or the fuse is blown.

③When no external battery is connected, it may be judged that the rechargeable battery is broken, or the power board/charging control board is faulty and the battery cannot be charged.

Troubleshooting method: connect all the connecting parts reliably, connect the AC to charge the instrument.

2. White screen, Huaping

Fault phenomenon: There is a display after booting, but a white screen and a blurred screen appear.

Inspection method: white screen and blurred screen indicate that the display screen is powered by the inverter, but there is no display signal input from the main control board. You can connect an external display to the VGA output port on the back of the machine. If the output is normal, the screen may be broken or the connection between the screen and the main control board may be poor. If there is no VGA output, the main control board may be faulty.

Remedy: replace the monitor, or check whether the wiring of the main control board is stable. When there is no VGA output, the main control board needs to be replaced.

3. ECG has no waveform

Symptoms of failure: connect the lead wire but there is no ECG waveform, and the display shows "electrode off" or "no signal received".

Inspection Method:

① Check the lead mode, if it is five-lead mode but only three-lead connection is used, there must be no waveform.

② After confirming the location of the ECG electrode and the quality of the ECG electrode, exchange the ECG cable with that of other machines to confirm whether the ECG cable is faulty, whether the cable is aging or the pin is broken.

③ If the failure of the ECG cable is ruled out, the possible cause is that the "ECG signal line" on the parameter socket board is not in good contact, or the ECG board, the main control board connection line of the ECG board, and the main control board are faulty.

Method of exclusion:

① Check all the external parts of the ECG leads (the three/five extension wires in contact with the human body should be connected to the corresponding three/five contact pins on the ECG plug. If the resistance is infinite, it means that the lead wires are broken, then lead wire should be replaced).

②If the ECG display waveform channel shows "no signal reception", it means that there is a problem with the communication between the ECG measurement module and the host, and the prompt still exists after turning off and on again, and you need to contact the supplier.

4. ECG waveform disorder

Fault phenomenon: The ECG waveform has a lot of interference, and the waveform is not standardized or standard.

Inspection Method:

①First of all, interference from the signal input terminal should be eliminated, such as patient movement, failure of ECG electrodes, aging of ECG lead wires, and poor contact.

②Turn the filter mode to "monitoring" or "surgery", the effect will be better, because the filter bandwidth in these two modes is wider.

③If the waveform effect is not good after surgery, please check the neutral ground voltage, which is generally required to be within 5V, and a ground wire can be pulled separately to achieve good grounding.

④ If the grounding does not work, it may be due to interference from the inside of the machine, such as poor shielding of the ECG board. At this time, you should try to replace the accessories.

Remedy: adjust the ECG amplitude to an appropriate value, and the entire waveform can be observed.
