17.6 Verifying the ECG
The ECG signal may be inaccurate due to hardware or software problems. As a result, the
ECG wave amplitude becomes greater or smaller.
To verify the ECG waveform amplitude:
1. In the main menu, tap [Maintenance].
2. Input the maintenance passcode.
3. Tap [Accept].
4. In the [Maintenance] menu, tap [General].
5. Enable [Calibrate ECG].
A square wave appears on the screen and the message [ECG Calibrating] is dis-
played.
6. Compare the amplitude of the square wave with the wave scale. The difference
should be within 5%.
7. After completing the verification, disable [Calibrate ECG].
