c)The arrow pointer should be pointing at the “Normal” choice. If it is not, press
MOVE until it is.
d)Press CHANGE to return to the main menu.
5.To set the pulse width to 1 us:
a)Press the MOVE button until the arrow pointer is pointing at the pulse width menu
item.
b)Press the CHANGE button. The pulse width submenu will appear. Rotate the
ADJUST knob until the pulse width is set at 1 us.
c)Press CHANGE to return to the main menu.
6.At this point, nothing should appear on the oscilloscope.
7.To enable the output:
a)Press the MOVE button until the arrow pointer is pointing at the output menu item.
b)Press the CHANGE button. The output submenu will appear.
c)Press MOVE until the arrow pointer is pointing at the “ON” choice.
d)Press CHANGE to return to the main menu.
8.To change the output amplitude:
a)Press the MOVE button until the arrow pointer is pointing at the amplitude menu
item.
b)Press the CHANGE button. The amplitude submenu will appear. Rotate the
ADJUST knob until the amplitude is set at 250V.
c)Observe the oscilloscope. You should see 1 us wide pulses. The voltage across
the current probe (Tektronix CT2 or Pearson 2878) should correspond to a
measurement of 5 A of current. (A series-connected current-sensing resistor may
also be used to measure the current, but this method often produces pronounced
overshoot on the rising and falling edges. This is a measurement artefact, and is
not present on the actual current waveform. This may be confirmed by using a
current probe.)
d)Press CHANGE to return to the main menu.
9.Repeat the last step, but set the amplitude to zero.
10.This completes the operational check.
