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.

User Maintenance >>
] → enter the
required password and then select [
Calibrate ECG
] from the popup menu. A square
wave appears on the screen and the message [
ECG Calibrating
] is displayed in the
ECG waveform area.
2. Compare the amplitude of the square wave with the wave scale. The difference should
be within 5%.
3. 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.
