POLARITY switch on the front panel can change the polarity of the output waveform The polarity is Normal when the NOR indicator is lit In this case the high voltage will appear on the OUTPUT as a positive pulse relative to the RETURN jack When the polarity switch is in the Reverse position REV indicator is lit the high voltage will appear on the OUTPUT as a negative pulse relative to the RETURN jack The polarity switch only operates when the CHARGE LED is lit i e the output is not charged Note that the voltage meter may indicate that some residual voltage is present on the main storage capacitor even when the tester is first turned ON This is due to inherent charging of the internal capacitors Pressing the TRIGGER switch will discharge the capacitors be sure not to touch the output and return leads when pressing the trigger switch Note that the peak amplitude of the measured output waveform is proportional to the voltage that 1s read on the front panel of the MegaPulse but it will always be somewhat lower This is because the meter on the MegaPulse is measuring the voltage on the main impulse storage capacitor This voltage will intentionally dissipate to some extent before reaching the output leads Therefore it 1s important to measure the peak amplitude of the output waveform and adjust the output of the MegaPulse accordingly Section 2 Getting Started This section contains information for the unpacking inspection preparation f
