letters DISCHARG appear above the switch.
b. Select Voltage with the FUNCTION switch. The word VOLTAGE
appears above the switch.
c. Enter the value by turning the Adjust knob. The programmed value
appears on the Discharge Voltage display.
d. As the Adjust knob is turned, the discharge voltage is entered auto-
matically into the selected memory.
5. Select the discharge current limit. For initial start-up and training pur-
poses, select 1.00A.
a. Select the Discharge power supply with the MODULE switch on the
front panel. The letters DISCHARG appear above the switch.
b. Select Limit with the FUNCTION switch. The word LIMIT appears

6. Select the cathode filament current limit.
Refer to the
“Tables” on page 83
for current limits for various ion
sources.
a. Select the Cathode power supply with the MODULE switch. The
word CATHODE appears above the switch.
b. Select Limit with the FUNCTION switch. The word LIMIT appears
above the switch.
c. Adjust the current limit up or down as needed. The value appears
