25.4 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 >>]→[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.
25.5 Calibrating the Touchscreen
1. Select [Cal. Screen] QuickKey, or [Main Menu]→[Maintenance >>]→[User
Maintenance >>]→enter the required password→[Cal. Touchscreen].
2. The
symbol will, in turn, appear at different positions of the screen.
3. Select, in turn, the central point of the
symbol.
4. After the calibration is completed, the message [Screen Calibration Completed!] is
displayed. Select [Ok] to confirm the completion of the calibration.
