rent in amps is usually set equal to or up to 10% greater than the
discharge current.
• Use the white Select button on the Discharge Power Supply to se-
lect Volts. Turn the knob on the Discharge Power Supply until the
discharge voltage is set to maximum as indicated on the Discharge

atmosphere.
• The discharge voltage will vary slightly during this time. Adjust the
gas
fl
ow after the 10 minutes to obtain a discharge voltage of ap-
proximately 120 V.
• At this point the operating conditions can be saved as a program to
