Similar examples are given in the dc source Programming Guide using SCPI commands.
1 - Setting the Output Voltage and Current
Set the output voltage
Action
1.
To enter an approximate value without using the voltage menu: On the Entry
keypad, press É or Ê to select the 1's digit in the voltage field. Then rotate
the front panel RPG knob to obtain 7 V.
If the unit is in CC mode, you won't see the output voltage change until the
voltage setting is low enough to cause the unit to go into CV mode.
2.
The easiest way to enter an accurate value: On the Function keypad, press
Voltage. On the Entry keypad, press 7, Enter.
3.
To make minor changes to an existing value: On the Function keypad, press
Voltage. On the Entry keypad, press É or Ê to select the digit in the numeric
field that you wish to change. For example, move the flashing digit to the ones
column to change a value in this column. Then, press Ë to scroll from 7.000
to 8.000. Then press Enter.
Set the output current
Action
1.
To enter an approximate value without using the current menu: On the Entry
keypad, press É or Ê to select the tenths digit in the current field. Rotate the
front panel RPG knob to obtain 0.9A.
If the unit is in CV mode, you won't see the output current change until the
current setting is low enough to cause the unit to go into CC mode.
2.
The easiest way to enter an accurate value: On the Function keypad, press
Current. On the Entry keypad, press ., 9, Enter.
3.
To make minor changes to an existing value: On the Function keypad, press
Current. On the Entry keypad, press É or Ê to select the digit in the numeric
field that you wish to change. For example, move the flashing digit to the tenths
column to change a value in this column. Then, press Ë to scroll from 0.900
to 1.000. Then press Enter.
Enable the output
Action
1.
On the Function keypad, press Output On/Off to enable the output. The Dis
annunciator will go off, indicating that the voltage is now applied to the
output terminals. The A display indicates the actual output current.
