LifePak TCP-Trouble Shooting

TCP - Charge Time

1. Make sure the paddles are securely stored in the paddle storage area of the defibrillator.

2. Press ENERGY SELECT to set the selected energy to 360J.

3. Simultaneously start the timer and press CHARGE.

4. Stop the timer when the defibrillator reaches full charge. Confirm that the time required to reach full charge is less than 10 seconds.

5. Simultaneously press both paddle discharge pushbuttons to transfer the energy into the test load.

TCP - Output Waveform

1. Place the paddles on the energy meter electrodes. Place the APEX paddle on the right electrode of the energy meter so that the pulse polarity is positive.

2. Connect the storage oscilloscope to the energy meter signal output.

3. Set up the oscilloscope for the "single shot" acquisition mode for the pulse waveform capture. Refer to the Operating Instructions for the oscilloscope for assistance. For waveform parameter measurement, place both the left and right measurement markers at both the 50% and 10% levels.

4. Press ENERGY SELECT to select 360J.

5. Press CHARGE.

6. After the defibrillator reaches full charge, simultaneously press the paddle discharge pushbuttons to transfer the energy into the energy meter.

7. Inspect the waveform displayed on the oscilloscope and confirm that the waveform meets the specifications listed below and illustrated in Figure 3—9.

Peak Current = 46A to 64A peak
Time above 50% = 2.10ms to 4.20ms
Time above 10% = 3.10ms to 9.20ms
