23.3 Checking Monitor and Module Information
To view the information about system start time, selftest, etc., select [Main Menu]→[Maintenance >>]→[Monitor
Information >>]. The information will not be saved after the patient monitor is shut down.
You can also view the information about the monitor configuration and system software version by selecting [Main
Menu]→[Maintenance >>]→[Software Version >>].
23.4 Calibrating ECG
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 calibrate the ECG module.
1. Select the ECG parameter window or waveform area→[Filter]→[Diagnostic].
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 out the square wave and wave scale and then measure the difference between them if necessary. If the
difference exceeds 5%, contact your service personnel.
