Measuring Synchronization
The Analyzer measures the synchronization time (cardioversion delay time) of
synchronized defibrillators. A 90 BPM ECG waveform is output through the
ECG jacks and the paddle plates. During normal operation, the defibrillator
recognizes and responds to this trigger by discharging within a certain amount
of time.
The Analyzer is capable of measuring up to 199.9 ms in delay time from either
the peak or the base edge of the R wave. Typical acceptable delay times are
within 60 ms from the peak of the R wave.
To measure synchronization:
1. Turn the defibrillator to be tested to ON and select the desired energy
output in accordance with the manufacturer’s instructions.
2. Connect the ECG patient leads to the Analyzer as shown in Figure 2-7.
3. Power up the Analyzer by sliding the power switch forward to the ON
position. The Analyzer displays Main Menu 1:

4. Press the SYNC softkey to enter the Sync menu:
