The ECG signal may be inaccurate due to hardware or software problems. As a result, the ECG wave amplitude becomes
greater or smaller. In that case, you need to verify the ECG module.

2. Select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the required password→[Module
Maintenance >>]→[Calibrate ECG]. A square wave appears on the screen and the message [ECG Calibrating] is
displayed.
3. Compare the amplitude of the square wave with the wave scale. The difference should be within 5%.
4. After the calibration is completed, select [Stop Calibrating ECG]
You can print the square wave and wave scale and then measure the difference between them if necessary. If the
difference exceeds 5%, contact your service personnel.
26.5 NIBP Leakage Test
The NIBP leakage test checks the integrity of the system and of the valve. It is required at least once a year or when you
doubt the measured NIBP. If the test failed, corresponding prompt messages will be given. If no message is displayed, it
means no leakage is detected.
Tools required:
 An adult cuff
 An air tubing
 A correct sized cylinder
Follow this procedure to perform the leakage test:
1. Set the patient category to [Adu].
2. Connect the cuff to the NIBP connector on the monitor.
3. Wrap the cuff around the cylinder as shown below.
