Operating Instructions
The Code 360 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 Code 360.
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 with 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 features
Front Keyboard and Voltage Knob Enable
If the MegaPulse 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. Disconnect the high voltage cables from the output connectors.
3. Turn the rear-panel Power Switch ON.
4. Press the red TRIGGER button to discharge the main capacitor into the internal resistor of the MegaPulse
unit.
5. Turn the rear-panel Power Switch OFF.
