8. To enable the output:
•
Press the MOVE button until the arrow pointer is pointing at the output menu
item.
•
Press the CHANGE button. The output submenu will appear.
•
Press MOVE until the arrow pointer is pointing at the “ON” choice.
•
Press CHANGE to return to the main menu.
9. To change the output amplitude:
•
Press the MOVE button until the arrow pointer is pointing at the amplitude menu
item.
•
Press the CHANGE button. The amplitude submenu will appear. Rotate the
ADJUST knob until the amplitude is set at +200V.
•
Observe the oscilloscope. You should see 1 us wide, 200V pulses.
•
Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should
vary.
•
Reduce the amplitude to 50V, using the adjust knob.
•
Change the output polarity by pressing the “+/-” button. The output amplitude
should become negative, and you should see -50V pulses on the oscilloscope.
(Avoid switching polarity when the amplitude is higher than 100V. Reduce the
amplitude first.)
•
Rotate the ADJUST knob. The amplitude as seen on the oscilloscope should
vary.
•
Press CHANGE to return to the main menu.
10. Repeat step 9, but set the amplitude to zero.
11. This completes the operational check.
