3. Use the MEMORY switch to select the memory location the power sup-
ply will use to store parameters; the selected memory location appears
above the switch.
4. Select the discharge voltage. For initial start-up and training purposes,
select 55V.
a. Select the Discharge power supply with the MODULE switch on the
front panel. The word DISCHARGE appears above the switch.
b. Select Voltage with the FUNCTION switch and the word VOLTAGE
appears above the switch.
c. Enter the chosen value by turning the Adjust knob. The value
appears on the Discharge Voltage display.
d. The discharge voltage is entered automatically into the selected
memory as the Adjust knob is turned.
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 word DISCHARG appears above the switch.
b. Select Limit with the FUNCTION switch. The word LIMIT appears
above the switch.
c. Enter the chosen value by turning the Adjust knob. The pro-
grammed value appears on the Discharge Current display.
d. The discharge current limit is entered automatically into the
selected memory as the Adjust knob is turned.
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
on the Cathode Filament Current display.
Different sizes and different types of filament wire may require adjustments
to the cathode filament current limit. Unless the source size is known, the
cathode current limit will be factory-set at 6.5A.
d. The final selected value is stored automatically in the memory, as
indicated above the MEMORY switch.
