Maintenance Verifying the ECG
TM80 Telemetry Monitor Operator’s Manual 17 - 5
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 Parameter Setup.
2. Tap ECG and set Filter to Monitor.
3. In the main menu, tap Maintenance.
4. Input the maintenance passcode and tap Accept.
5. In the Maintenance menu, tap General.
6. Enable Calibrate ECG.
A square wave appears on the screen and the message ECG Calibrating is dis-
played.
7. Compare the amplitude of the square wave with the wave scale. The difference
should be within 5%. If the difference exceeds 5%, contact your service personnel.
8. After completing the verification, disable Calibrate ECG.

The NIBP accuracy test is required at least once a year or when you doubt the measured
NIBP result. Contact your service personnel to perform NIBP accuracy test.
17.8 NIBP Leakage Test
The NIBP leakage test checks the integrity of the system and of the valve. It is required at
