Immediate Action Keys

Immediate action keys immediately execute their corresponding function when pressed. Other function
keys have commands underneath them that are accessed when the key is pressed.
This key toggles the output of the dc source between the on and off states.
When coupled, the key affects both output channels. It immediately executes its
function as soon as you press it. When off, the dc source output is disabled and
the Dis annunciator is on.
Press this key to reset the protection circuit and allow the unit to return to its
last programmed state. The condition that caused the protection circuit to
become active must be removed prior to pressing this key, or the unit will shut
down again and display the Prot annunciator again.
Press this key to toggle between OCP enabled and disabled. If OCP is enabled
the output will become disabled if the output mode changes from CV to CC
mode. The OCP annunciator indicates the state of OCP.

Scrolling Keys

Scrolling keys let you move through the commands in the presently selected function menu.
Press to bring up the next command in the list. Press to go back
to the previous command in the list. Function menus are circular; you can
return to the starting position by continuously pressing either key. The
following example shows the commands in the Input function menu:
CURR:RANGE <char>
CURR:DET <char>
