Testing
This section describes how the MegaPulse 1.2x50-16PF PV tester is used to conduct a test. The
test can be stopped immediately at any time by turning OFF the rear-panel power switch.
1.
Connect the tester to a proper source of supply using the included 18 AWG power supply
cord.
2.
Connect the red and black test leads to the EUT.
3.
Turn the tester on. Toggle the
POLARITY
switch if necessary to select the output
waveform polarity:
NOR
for positive polarity, and
REV
for negative polarity.
4.
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).
5.
Adjust the digital
VOLTAGE
knob to the desire value: press the voltage knob to display
the voltage set point. This setting will blink for a few seconds on the front meter. Turn
Clockwise to increase the setting Voltage Setting Point.
6.
Push the yellow
CHARGE
button. Verify the red
TRIGGER
indicator is now lit.
7.
After the front panel meter indicates that the desired test voltage has been reached, push the
red
TRIGGER
button.
8.
Turn the rear-panel power switch OFF.
