Safety Techniques
The high voltage circuit of the MegaPulse 1.2x50/8x20-2PF-HR 2/12 ohm can be shut off at any time by turning OFF
the rear power switch. Always press TRIGGER to discharge the tester before turning OFF.
The MegaPulse tester is provided with a digital
VOLTAGE ADJUST
knob on the front panel. This voltage setting
should always confirm by pressing the
VOLTAGE ADJUST
knob before starting any testing.
The MegaPulse tester is provided with a
CHARGE
switch that is in the unarmed "Standby" setting when the tester is
first turned ON. When the yellow
CHARGE
button is lit, the tester will not provide high voltage until the
CHARGE
Button and the
TRIGGER
Button have been pressed in order. To prevent inadvertent operation, the operator should
be instructed not to press the
CHARGE
Button until the test is ready.
The MegaPulse tester has been designed for one-touch operation with the right hand or via PC TestMinder. The
equipment under test should be connected to the MegaPulse tester and then left alone by the operator. After the
operator is clear of the Tester and the equipment under test, the operator should turn the rear-panel power switch to
ON. For Manual Operation press the Voltage Knob and set the desired voltage, then press
CHARGE
Button, after
charge stops at set voltage operator can press the
TRIGGER
Button, with his right hand. This will allow the greatest
separation between the operator and the test being conducted. Note that the CHARGE process will stop after 2 minutes
if the TRIGGER button is not pressed.
The MegaPulse tester is designed to bleed the high voltage away after the test has concluded. In order to ensure that
any voltage present in the equipment being tested has been completely bled away, the operator should not unplug the
equipment under test from the MegaPulse until the front panel meter reads a safe level (20 volts or less). Pressing the
TRIGGER button before disconnecting main power (or turning the equipment off) will ensure that the internal
capacitors are discharged as much as possible, however, the tester connects a Safety discharge network to main
capacitor to bleed the capacitor when is turned off or loss of power occurs.
