*** WARNING ***
THESE NEXT STEPS ARE DANGEROUS.

Connect the power to the supply and turn on the main power switch. The "Ready" Indicator should light.

Set the voltage to 50 percent and press the HV ON pushbutton.

The HV ON Indicator will light and you will hear a slight hissing sound. This is okay. If you hear any snaps or arcing, determine where the problem is, shut off the supply, and dope the area. When it dries, test again.

With a grounded screw driver, bring the tip of the screw driver in close proximity to the output stud and watch for sparks.

*** WARNING ***
DO NOT TOUCH THE OUTPUT STUD WITH THE SCREWDRIVER. PERMANENT DAMAGE WILL RESULT.

If you are confident in your building skills, or hungry for sparks, SLOWLY ramp up the voltage to 100 percent and test again with the screwdriver.

Success will be indicated by the 2 inch long spark that you get from the supply.

*** WARNING ***
DO NOT ATTEMPT TO MEASURE THE OUTPUT OF THIS DEVICE WITHOUT SPECIAL TEST EQUIPMENT OR THE PROPER SAFETY EQUIPMENT.

*** DANGER DANGER DANGER DANGER DANGER DANGER ***

THE CURRENT PRODUCED BY THIS SUPPLY ALONG WITH THE HIGH VOLTAGE MAKES THIS DEVICE DANGEROUSLY LETHAL! DO NOT TOUCH THE HIGH VOLTAGE STUD DURING OPERATION. THIS THING WILL KILL YOU! GROUND THE STUD AFTER EACH SHUTDOWN TO DRAIN ANY REMAINING POTENTIAL.

If you connect the leads reverse it will be -50 as well

Yes it will be -50 wrt the other lead but not -50 wrt earth ground.

How can you make it -50 wrt earth ground? This will allow it to be used as a negative ion generator.
