1. Press the SET key to select the Output Settings Mode. A blinking cursor

will appear in the voltage field of the display.

2. Use the 

buttons to key in the desired output voltage

value, then press SET. The blinking cursor will move to the current field

of the display.

3. Use the 

buttons to key in the desired current limit, then

press SET to exit the Output Settings Mode. The display will return to

the actual V and I display mode.

GPIB commands for setting the output voltage and current limit:

:source:voltage xx.xxx

; set output voltage,

xx.xxx is between 0 and 20

:source:current:limit x.xxxx ; set output current limit,

x.xxxx is between 0 and 5

and

:sense:current:range minimum ; set to 5 mA range

or

:sense:current:range maximum ; set to 5 A range
