Operating Instructions
The D5-PF Medical Defibrillation tester consists of two parts; the pulse generation portion and the measurement
portion. Please refer to the general electric circuit shown in Figure 3 to show the function of the D5-PF.
The following procedure will explain how to generate a high voltage pulse with the MegaPulse unit.
External Interlock
The external interlock is a two-position terminal block located on the rear panel. When the External Interlock is open:

TRIGGER and CHARGE lights will be blinking.

The front keyboard will be disabled.

If the unit is connected to a computer with the TestMinder software, the interlock status will be
shown on the computer, condition that will also disable polarity changes, charge, and trigger
conditions.
When the Interlock is closed, it enables all normal operations of the MegaPulse D5-PF features.
Front Keyboard and Voltage Knob Enable
If the MegaPulse D5-PF tester has disabled the keyboard or Voltage Knob, it is possible to enable them by using the
next keyboard sequence:
1. Turn OFF the MegaPulse P tester.
2. Press and hold the TRIGGER and NOR-REV buttons .
3. Turn ON the MegaPulse tester.
4. Wait until the display shows rESE.
5. Release the TRIGGER and NOR-REV buttons.
Discharging Residual Voltage
Note that the Voltage meter may indicate that some residual voltage is present on the main storage capacitor, even
when the MegaPulse tester is first turned ON. This is due to inherent charging of the internal capacitors. The following
procedure will explain how to discharge a remaining voltage stored on the main internal capacitor.
CAUTION
High voltage generated by the MegaPulse tester is exposed during this test. A risk of shock exists.
Exercise care when using the MegaPulse unit.
1. Turn the rear-panel Power Switch OFF.
2. Set AUX OUTPUT switch to “Return” position.
3. Set S3 switch to “Open” position.
4. If the MegaPulse includes option 100X, install the 100X jumper on the rear panel.
5. If the MegaPulse includes option 34, set the Trigger time switch to 200mS, install the 50k ohm jumper on
the front panel.
