Polarity Pulse Selection
NOTE
If the red Trigger light is lit or more than 200V remains on the internal capacitor, the polarity pulse
selection will be automatically blocked for safety reasons.
1.
Turn the rear-panel Power Switch ON. Positive polarity always is set by default after the unit is turned ON.
2.
Press the POLARITY switch button to toggle between positive and negative.
Voltage Set Point Adjustment
NOTE
If the front display shows the word “Off” when trying the adjustment, it means the front Voltage knob has
been disabled by the Testminder software. See section “Front Keyboard and Voltage Knob Enable”
To adjust the Voltage Set Point:
1.
Press the VOLTAGE Adjust knob one time to enable the adjustment mode, digits for thousands and hundreds
will start blinking for a few seconds.
2.
While the digits are still blinking, turn the VOLTAGE Adjust knob, clockwise or counterclockwise, to change
the value of the blinking digits.
3.
While digits are still blinking, press the VOLTAGE Adjust knob again and the tens and unit digits will start
blinking for a few seconds.
4.
While the digits are blinking, turn the VOLTAGE Adjust knob, clockwise or counterclockwise, to change
the value of the blinking digits.
5.
After a few seconds without any change on the VOLTAGE Adjust knob, the desired output voltage will be
set.
Charge and Trigger a Pulse
The following procedure will explain how to generate a high voltage pulse with the MegaPulse unit. The MegaPulse
1.2x50/8x20-2PF-HR Tester is capable to maintain a specific voltage charge selected by the Voltage Set Point.
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.
Confirm the Voltage Set Point by pressing the VOLTAGE Adjust Knob, the current setting will blink for a
few seconds on the front meter.
2.
If a different Voltage Set Point is needed it, refer to section “Voltage Set Point Adjustment.”
3.
Push the yellow CHARGE button to start charging the internal high voltage capacitor and wait until the front
meter reaches value set on Steps 1 or 2. Verify that the red TRIGGER indicator is now lit.
4.
Once the desired voltage is reached, press the red
TRIGGER
button to deliver the high voltage pulse (be
sure not to touch the output and return leads when pressing the trigger switch).
5.
Turn the rear-panel Power Switch OFF.
